In this vid we swap out a usdm ej205 for a single avcs jdm ej205. This information pertains to usdm 02-05 wrx's. There 2 ways to do this swap, This is the way In which you would remain using your usdm ecu. The other way is to utilize the intake avcs, to do so you need a jdm 16bit single avcs ecu and it must match your cars transmission type. Auto or manaul
Using the jdm ecu renders your cobb ap useless, kinda like it was before anyway.
To tune the jdm ecu you will need an open source tune. To complete the wiring for the jdm 205 running avcs you only need to de pin 4 wires on driver side plug and add an additional 4 wires on passenger side. Iwire.com makes a simple kit for this if needed as well. - Auta a dopravní prostředky
I love that you explained all the pipes, breathers etc on the block.. great to see how and where those parts connect to..
You guys are livesavers! Thank you so much for this
excellent video. great explanations. I appreciate you going over all the hoses and connections needed. Doing mine now.
I appreciate you putting out this video. I have an '03 USDM WRX Auto and spun a rod bearing back in 2020... it's been sitting in my garage for almost 3 years and I've just gotten hold of a JDM EJ205 to put in. I've been combing through iwire pages and your video to reference everything else I should need and would need to transfer from the old engine. Hoping to get everything done in a couple weeks through a shop! Cheers.
Glad you found it!
If you are using the matching jdm 205 ecu, I actually have a video doing that as well. I was installing a jdm 207 which is actually exact same process but go through the simply wiring needed. The iwire kit really does make it simple.
Come back if you need any help.
Another good vid Jesse, keep it up boys!
Thank you for this, I'm currently in the same exact process and this video was exactly what I needed. Hard to find info on the little nuances for jdm avcs swaps into a usdm wrx.
boutta do this im excited!
You guys are legends! Exactly what I was looking for... thank you so much for explaining in details of what needs to be swapped over to Domestic car. Here I thought that swapping of cam gear and crank shaft gear was required as well. You made me so happy. :)
So simple eh!
@@TheSubieSanctuary 😁 Looks pretty strait forward. Now I need to visit Ebay and shop around for an engine.
cobuman hit up japandirect they are local to me and ship world wide. Tell them i sent you. They will hook you up
@@TheSubieSanctuary I'll check them out. Thanks! I found this website which I'm assuming is them; they have this drive by cable engine...www.japandirectjapanese.com/subaru/impreza-wrx-sti-2002-2003/jdm-subaru-impreza-wrx-ej205-ej20-dohc-2-0l-turbo-engine-2002-2004-2005-2005-motor-with-avcs-gd-gg.html and another just like the one in video. I guess the actual from jspec WRX has drive by cable and the other is from Forester... any difference in those engines besides throttle? I'm assuming intake has to be changed regardless because of sensors need to be changed anyway.
cobuman thats it brother! And a good deal for online actually!!!
Nice job sir 😊
>Using the jdm ecu renders your cobb ap useless, kinda like it was before anyway
Love you guys hahaha excellent work.
🙏
If you’re Subaru owner, it’s nice to see you again in this video 😂 😂😂😂
Good stuff...
I just recently did this
Crank no start 🚧🚧
Fuel lines backwards is a common one
Awesome video. Not trying to be a critic, but it sounds like that engine has a knock and it was pretty defined when you are near the engine bay.
It is still going to this day
EJs are pretty noisy. Especially when cold. Last rebuild I did was new oem shortblock and totally rebuilt heads, sounded exactly like it did before the job and continued for over 180k miles without any issues.
Hi guys, thanks so much....learning a ton from watching your videos. I'm in the research phase right now and here is my goal - to swap out my US EJ205 from an 04' WRX with a JDM EJ205 with as little hassle as possible. Swap over the manifold, keep the TGVs, move over all the stuff you highlighted in your video, plug and play with my US harness and hopefully NOT have to send out for a tune. I'm thinking I can buy an AVCS equipped motor and not hook it up or do it at a later time. No switching of cam gears or wiring alterations. I see a lot of EJ205 non-AVCS motors out there but according to the IWIRE website, these are a first generation from 99-00 vehicles and I'd like the newer generation (they say 2001and new all come equipped with AVCS). See anything wrong with my thought process here? Thanks!!!
You are correct in the jdm non avcs engines coming from the pre GD cars.
All the jdm 01+ wrx avcs. You can simply get an avcs engine and install as I did in the video and you are good to go!
@@TheSubieSanctuary Hi guys, a question here. We've installed the engine successfully; Running the USDM ECU with AVCS not hooked up yet. Runs well but will intermittently throw a P0340 cam position sensor code where the the engine will misfire a little when under moderate load but drives fine and idles ok under no load. Code usually trips when accelerating into the mid to higher RPMs. Things I've tried to fix it: Switched out cam position sensor with the one from the JDM engine and checked their ohm readings (1.966 and 2.2 kohms), verified wiring continuity at the harness plug, and check voltage on the alternator (14.1 volts under no load and 13.45 under load - initially started with the JDM alternator and switched back to the US; exact same part numbers). We didn't have this problem before - just wondering if you have run into this after a JDM swap and if you have any suggestions. Thanks!
This was a great video but I was wondering if I got a drive by cable jdm engine would I still need to swap over the intake manifold and all that stuff?
Sup guys, great vid I'm doing this swap this weekend and following weekend, and I was hoping I could get some thing cleared up I may just be overthinking it but anyway, I wrote down everything I need to replace and swap but theres other videos saying you need to do "more" than this video suggests, so do I need to replace my timing belt (which one is best if so?) crank pulley(s), or my water pump? Thank you in advance
To make it work without issue you do only need to do what we did in this video.
You dont need to replace your timing belt unless you want to. Best water pump is aisin.
I’m sure you guys hear this all the time and probably tired of hearing it by now, looking at the comments to see if some are similar to my question but here I go lol.
Recently purchased a complete, bone stock ‘05 WRX from the original owner. Had it for 3 weeks, and spun a rod bearing. So, I purchased a JDM EJ205 Non-AVCS motor. I’m planning to pull the existing USDM motor out the car this weekend. The parts you mentioned in this video to swap from the USDM to the JDM are all I need? Nothing crazy like the cam sprockets and gears. Just stick to what you mentioned and I should be alright? Lol. Just on edge and this process is making me want to bite my nails off with anxiety.
No worries, since your donor is the jdm non avcs engine. We personally dont see alot of those. To be sure just check crank gear and driver cam gear. Im 99% they will be exact same as yours anyway. But its a lot easier to check while out.
Other then that, im unfamiliar with those jdm intake manifolds. They may be the same, but if they are not, then swap over your complete intake manifold
@@TheSubieSanctuary awesome! Thank you so much 🤙🏽
@Vst eric bro it was cake honestly. I used a JDM EJ205 longblock NON-AVCS which is key. IF you get a AVCS motor to put, you’ll need a new harness to adapt to the variable valve timing essentially…
Now, if you have a NON-AVCS to put into a 05 bone stock like me… you don’t need anything crazy or swap anything bro. I used the original turbo, manifold, etc to transfer from the old blown motor to the new one 🤙🏽🤙🏽. Now for me in the process of the swap, I replaced:
New Clutch, new turbo, new exhaust manifold, thermostat, idler pulley for the A/C , bunch of shit
@Vst eric I was reading the same thing but I never ended up switching the sprockets. Timing feels great for my bone stock ‘05 WRX. Motor has 45k total miles and I only broke it in so far at 700 miles. I spoke to a tuner in Colorado here, and they said no tune necessary. Only if for whatever reason check engine comes on he said but mine never did. It’s all plug n play. The JDM motors have better heads. Free flowing heads from Japan.
@Vst eric that’s fair, yeah man originally from San Diego been out here for awhile. Cali is wack when it comes to modifications
I recently just got a jdm ej205 that came with tf035 turbo and single avcs. I’m doing a very similar swap into my bugeye so I’m super thankful for your info in this vid! But I have one question I keep reading on forums I have to change camshaft and others say change cam gears? Do you have any info on this?
I’m pretty much following everything you’ve pointed out and also using my td04 turbo, I’m just super curious about this camshaft and cam gear dilemma
@@brandonmayan4576 in this swap we did not switch the cam or the cam shaft. Not often do we unless instructed. The difference between the swapping cam shafts and cam gear vs not swapping them will almost be unnoticeable on a dyno.
We have hit 300whp simply dropping one of these engines in a wrx and swapping it exactly like in the vid. Obviously a bigger turbo on that one
I have a 02-05 jdm wrx engine what ecu do I need for it and it’s a auto trans
The oil feed line for the turbo doesnt seem to bend the right way to actually go into where its supposed to on the turbo and i cant figure out why but i cant use the old one from my usdm because the one on the avcs motor is much lonbger and routes to a different spot
Are you using a td04 or vf turbo?
Normally the swap will be able to use the jdm oil line on td04 no problem
So if I get a jdm 205 I can run it without using the avcs without having any issues?
Is there no need to swap out the crank pulley and driver side intake cam sprocket?
No sir, unless you got maybe an old ej20k instead of a 205
Hey guys with me is the other way around I have an ej205 with the double breathers on the sides but I recently got a jdm with the single breather is is the same process to make it run ?
Yes essentially the same. Use the single breather pcv system
Hi, I’m doing this swap now and I’m confused as to what happens with the 2 cam sensors on the back of the jdm engine. I swapped over the usdm intake manifold but it only has the one connector for the sensor on the drivers side, which I’m pretty sure is why I’m getting gross misfires on 1 and 3
The 2 cam angle sensors at back of engine. When using the usdm ecu, they will not be plugged in or used and will not cause any issue what so ever.
You may something else causing the misfire unfortunately.
4:36 did you use the oil feed that came with Jdm motor? I’m putting my td04 on the jdm motor as well and the oil feed line is almost an inch shy from the mounting area on my turbo. Has me wondering if I’m doing something wrong
Needs to be tweaked at bit to reach.
Your jdm, is it a 2 piece line vs your usdm being 1 piece.
Worst case if you can manipulate the jdm line to reach then youll have to get a braided stainless line. Typically this isnt the case though
@@TheSubieSanctuary yes the jdm is a 2 piece line and you were right, I just kept slowly bending until I got a good fit. Thanks!
been using this for a reference, great job guys. the only issue ive run into is that the avcs lines are kinda in the way for the intake manifold bolt holes to line up. right side sits down fine , but the fuel lines on the manifold hit the avcs line. any thoughts?
Ahh yes! 2 options:
1. Slightly adjust fuel line inward
2. Use that section of fuel line from the jdm, youll notice it kinda has a kink in it to clear avcs. Not too difficult if manifold still off
@@TheSubieSanctuary will see which one i end up with
thanks guys 🙏🏼
Thanks for the info and vid. I have a 2005 WRX Wagon. Since our cars don't have AVCS, would the non-AVCS engine be a better swap. Is there something you don't like about the non-AVCS engines? They're are about $400-600 cheaper.
Hey there, the non avcs 205 would be coming out of a pre 2001 jdm car. Getting to be pretty old and at our importers the non avcs 205 is rather rare now. For ease of access and a motor that is potential 5-7 years younger we end up with the jdm avcs ones.
There is nothing wrong with swapping in a jdm 205 non avcs. The swap is a simple as the swap we did in video. Just swap over intake entirely and your set
@@TheSubieSanctuary May I ask why it is necessary to swap the entire intake? Is it just for emissions? I don't have those restrictions where I live and would like to delete the TGVs.
@@velovoodoo102 most the ones we get are drive by wire engines. So its a different harness and not compatible. If you get a drive by cable version then you can drop it in as is!
I can’t build past 8psi of boost would it be because the jdm turbo is still on ?
Hey buddy, please subscribe! The jdm turbo will hit 14psi when stock. It could be a vac or boost leak or issue with wastegate. Any check engine codes?
Is there any other way to get around the extra breathers?, i dont have the jdm routing
Could just plug them with some oil resistant caps. (The extra valve cover ports/ 1 crank port) Or could use oil resistant hose and run lines and tee them into crank as well
Good video , how ever what about going a usdm ej205 avcs into a 05 wrx non avcs? This would be the same process ? Or any different thank you & hope a response
Normally a usdm 2005 205 would be non avcs. Unless you mean 2006 ej255. That opens up a big can of worms for the swap. Let me and i can point you in right direction
I have a jdm 6cyl I got for my outback. My throttle body cables have been connected but now there's a buzzing noise when I throttle it. Cranks but no sputter to start? Have any clue guys? if not it's cool
Was your outback already a 6cyl?
My tip would be, fuel?, Spark?, cam and crank position being recognized by ecu
Nice video I currently have the Jdm ej205 but has slot of issues and am going to put another Jdm 205 in there i have a Bugeye
If it has good compression and isnt knocking or overheating. Im sure a shop should be able to set it straight with some diagnostics. Worth a shot vs starting over
@@TheSubieSanctuary 👍🏽
Do you need a tune for the higher compression of the JDM motor?
This engine isnt a high comp engine, but some jdm engines are. It is definitely ideal to get a tune unless its a direct replacement of your original engine
In the video did you delete the AVCS system on the JDM engine?
No sir! Left it as is, not hooked up.
Still capable of 300whp with a sti turbo and capable tuner
I am planning to have this swap. How long did it take you guys to complete the job?
2 very casual days overall. 16 hrs at a pretty chill pace
Hey The Subie Sanctuary! I've been really confused about this topic. Getting multiple opinions and just want cold, hard facts to get this straight once and for all. Here we go...
My car will not get into boost at all. It wont even come out of vacuum to generate 1 pound. I recently finished swapping over all my accessories from a tuned
2.0 JDM NON-AVCS EJ 205 Long Block
To a
2.0L JDM AVCS EJ205 Long block
and its still falling on its face once past 3-4k. It idles fine, runs fine in vacuum but I have no boost.
I have checked everything visually, hoses, lines, wastegate lines, everything.
Im catless all the way back. From up pipe to downpipe. So it couldn't be a clogged cat.
I hear the turbo spooling but it literally just hits a brick wall and doesn't want to give any more, even though it sounds like it does, once im at 4,000 rpm's
I've been doing more research and getting second opinions from Master Techs at Subaru and they're saying it might be because if I don't swap out the JDM to USDM Cam Gear and Crank Sprocket, they will run at "full retarded" ?
But I've ALSO heard other people saying the exact opposite. That you don't have to swap over anything. Just the Coolant crossover pipe, the cam position sensor, crank position sensor, and the coolant lines from the water pump. And the car will start/drive/build boost with no problem.
Says you HAVE TO swap the Cam Gears: czcams.com/video/FV6AONm6pxk/video.html
Says you DO NOT have to swap the Cam Gears : czcams.com/video/0sSuzHPUH8g/video.html
Or can I just simply "Block them off" and get this from IAG?: subimods.com/wrx/2002-2003-wrx/engine/internal-components/iag-black-avcs-camshaft-sensor-delete-plugs-pair-2002-2005-wrx-w-avcs-heads.html
The cam gears are 10000% not your issue. Sounds like it could crazy ignition break up, or something just isnt hooked up right.
We dont swap the cam gears and several of our guys running jdm avcs 205 are hitting near 300whp without an avcs ecu!
Let me know how you make out, always curious to hear running issue outcomes.
@@TheSubieSanctuary The Techs at the Subie Dealership I work at are saying the cams are probably set at "Full Retarded" therefore not holding any oil pressure because the AVCS is stuck open? Im not too sure how avcs works, but thats essentially what he said.
@@PetrenkoShorts ive probably done 30-40 cars with this swap we certainly have never experienced that.
Ive experienced that symptom like hitting a wall at 3000/4000rpm right as car should be getting into boost. Its been Ignition break up, boost leak, bad maf, bad fpr etc. Always hard to guess though.
@@TheSubieSanctuary The car did have a really bad rough idle, but it turned out to be a small leaf stuck inside the wiring harness side, preventing one of the pins from making contact to the MAF Sensor. And i mean, after that, the idle was fixed. But i still ran into the problem of no boost after 4k rpm
@@PetrenkoShorts get a known good coil pack. Swap it out for 1 coil at a time and keep test driving the car each time.
Hey there. I’m looking at doing this swap into my 02 wrx 5mt dbc. Going to try and keep avcs working but having trouble getting solid answers on which ecus will work. The ones specifically numbered for WRXs always carry a stupid premium, and I know it isn’t necessary to use those specifically.
Can I use any ecu from a JDM avcs ej205? Or will it specifically have to come from a 5mt with DBC?
Will have to be a drive by cable ecu.
Early forester turbo, v7 sti, v7-v8 wrx
I have a vid on here as well on wiring the avcs etc.
@@TheSubieSanctuary excellent, so the trans it came from doesn’t matter?
@@detectivebloor4011 actually thats a good point. I believe it can only come from a manual trans donor car.
I have a avcs drive by cable ecu, a few actually (none for sale) but can send you the model numbers to hopefully help you find one.
The one in my personal bugeye came from a forester 😳
Hey there so if finally pulled the trigger on a JDM motor. Question, until I can get a tune. Will my usdm cobb tune be sufficient to run the motor safely? It would be on a stage 2 with supporting mods.
You will be fine, I would avoid beating on it to be safe though.
Thank you.
So I have 2 questions, for the oil feed line going to the turbo. You said on the US version its cut off? Does that mean I need to remove that line in order for it to work? Second question, going the route you went is there any tuning involved or can I just throw it in and go?
The difference in the turbo line between the 2. Is the usdm 205 picks up at back of cyl head and the jdm runs from avcs solenoid across head to turbo. Leave in place and use the jdm turbo feed line.
As for tuning, you can drop this engine in and leave un tuned if your car is all stock. However I will mention a tune is always beneficial for sake of efficiency. With that being said, we have had people leave these un tuned indefinitely without issue in stock form
@@TheSubieSanctuary is there a specific jdm 2.0 I should look for? From what I'm reading there's multiple variants of the jdm 2.0. I have a 2002 wrx wagon.
@@HondaTech69 there is technically 3 potentials. An early jdm 205 that will be non avcs and you can simply swap on your intake mani and harness, but will have to possibly swap the cam and crank gears.
Then there is a drive by wire jdm 205 with avcs and also a drive by cable jdm 205 with avcs.
If you get the non avcs you need no tuning. You can send a link of what you find if youd like
I tried responding to your message on insty but it says you need to accept my invite. @@TheSubieSanctuary
so u can use your cobb ap on it but ive heard it will need to be tuned or it can cause problems so is there a specific tune cobb has for that or nah?
Needs to be pro tuned, none of the cobb ots tunes will be exactly right for it
@@TheSubieSanctuary yoo thx bro!
I just picked up a 2005 wrx, from what i understand the old owner put a jdm engine in it, im not sure what exactly what was done to it, so please overlook my lack of knowledge. However koeo the oil control valve or (avcs selonoid) clicks constantly, start the car it stops, but once over 4500 rpm it starts clicking again (like a fast clicking) and will not stop until the car is shut off. I have pulled them out and confirmed its these selonoids going nuts (driver and pass side). Dont know if its relevant but the tumble generators are not present so the plugs for them are not connected to anything. Any input on what could be causing this solenoid spaz? Im at the point of just unplugging the selonoids because i dont think their doing anything useful anyways. Will doing so hurt my engine long term or should i just let them tap away?
Please get back to me, i love this car and trying to figure out wtf is going on
Ya they must have messed something up wiring those solenoids. Ive never heard of them acting like that.
You can watch live data on high end obd scanner to see what ecu is telling them to do and if otherwise they function correctly as they are. There is no harm in unplugging them until you chose to dig into whats up with them.
@@TheSubieSanctuary appreciate it guys! Keep up the good work!
So I’m looking to a 2004 Subaru wrx it has a jdm ej205 and a oem ecu and it has a check engine light saying for a tune he says it needs to be tuned for the new engine. Would I be able to use a Cobb access port to tune for that and get rid of that check engine light?
Yes you can use cobb ap on the usdm ecu to tune check engine light
@@TheSubieSanctuary What tune would I need to use?
@@jordanv7903 no cobb ap tune will be correct for the jdm 205 with usdm ecu. Ideally you need it professionally tuned.
The cobb ap is just an interface for tuning the car the maps on the cobb are a waste of time themselves and wont do much good
are the head gaskets the same? usdm ej20 non avcs. and jdm ej20 single avcs? or do i need a special head gasket?
Same headgaskets!
@TheSubieSanctuary you are awesome!! You always respond and make some of the best content!! Thank you for all your help!!
I have a Legacy with a JDM EJ205 swapped in, with a USDM '03 WRX ECU. It runs and drives, but I don't think I'm getting all the power I should be. A few mechanics have told me I need to get the JDM ECU and wire it for AVCS. How are you making it work properly without the AVCS?
....actually it looks like they left the JDM intake. Is this why I'm having these problems?
We are just running it without avcs in this one.
Most of the jdm swaps we do, we do run the jdm ecu and wire in the avcs.
Very easy to do. Iwire.com sells the wire harness for $100 and you can get the jdm ecu for $100 no problem.
Did your jdm engine come with metal intake manifold on it? Or plastic
@@TheSubieSanctuary metal. When you swap without AVCS, though, are you getting full power? Like I said, my car runs fine, but it seems much slower than it should be.
hedgeclipper418 jdm 205 not running avcs vs usdm 205 will make the exact same power.
If I were to keep the tf035 turbo on the engine would it require a retune because of the usdm ecu
or a remap or any other things
No you dont have to re tune if using the tf035 and usdm ecu
so no cam gears have to be swapped out correct ?
Correct!
Where do you get parts for the JDM engine?
Any parts/gaskets are same as domestic model. With the exclusion of the valve cover gaskets. Those have to be ordered online for jdm 205/207
So in the middle of the swap do I use the Usdm oil feed for the turbo and if so do I need to do anything to the avcs?
Youll have to use the jdm oil feed line as it may be intergraded from avcs to back of cyl head to turbo.
You can do a few things with the avcs:
Leave it as is, or run a jdm 16bit ecu and wire your car for avcs, or swap your your usdm cams and cam gears.
@@TheSubieSanctuary my usdm turbo feed is a banjo bolt and the Jdm is threaded and flared like a brake line
@@jacobpainter5837 sounds like your missing the other part of the jdm line. The jdm is 2 piece, beyond that flared/threaded piece is normally the rest of the line to banjo bolt into turbo.
If you are missing it or for some reason it wasnt on your jdm turbo.
Then youll need the IAG stainless abcs line kit. It will cover avcs, cyl head and then to turbo.
@@TheSubieSanctuary thank you so much you are a life saver somehow I took it apart at that joint and off the turbo and had it in the junk Jdm parts. Again can’t thank you enough❤️
so i have a 05 wrx non avcs. i am planning on swapping the engine with a jdm 205 single avcs. would i have to change the driver's side intake cam gear?
on the video at 3:21 minutes he only says that "you need your cam sensor" but never mentions anything about the cam gear/sprocket!!
any help is appreciated. im really stumped on what to do...
No you dont have to change driver cam gear. Are you just going to be running your original ecu ?
@@TheSubieSanctuary yea, just the usdm ecu. I'm not too worried for the avcs, if I can find a jdm ecu down the road I might use the avcs. But for now I plan on getting a newer engine and tuning it a bit.
@@jorgetellez7969 ya youll be totally fine to install same way as i did in video
@@TheSubieSanctuary niceeee!!! hell yea. thank you for the help!! this was the last question i needed answered!! im glad i came across your vid!!
Does this apply to the dual avcs engine aswell?
I have a couple “how to” vids on the duel avcs engines. 1 for duel avcs jdm into duel avcs domestic and 1 for duel avcs jdm into domestic single avcs!
Let me know what your looking for and i can link vid! Or check out our “how to” playlist
In the middle of this swap, with usdm ecu the car misfires/backfires and has trouble idling, with JDM ecu it just keeps cranking no start, also I don’t have the intercooler on yet just trying to see if the engine is healthy... any advice!?
Only way it will run without intercooler is if you unplug the maf sensor. Try that and report back.
Jdm ecu requires some wiring to be done or else youll be sending signal to tgvs rather then avcs
@@TheSubieSanctuary It worked! Thank you guys! Also I figured out the body harness was not the original one so that’s what cause the backfires I’m assuming. I’m trying to help a friend do this swap, awesome vid! 👍
@@TheSubieSanctuary Alright so the car is idling and runs but for some reason it kinda sputters when driving normal but WOT it drives perfect.. any ideas? Sorry to keep bugging you guys
@@Nes_2k no worries buddy, that would just be me guessing without being able to see it. Things that most commonly cause that are maf or or front o2 sensor.
@@TheSubieSanctuary I’ll give it a try thank you guys 🙏
I’m putting the same Jdm 205 into a 03 wrx but I want to change the water pump out first with timing belt. My problem is the new motor doesn’t have an oil cooler so there are only 2 outlets on the water pump instead of the factory 3. Do you know what water pump to get for the Jdm ej205? I can’t use a USDM pump because I don’t have an oil cooler from the old engine.( it was a Jdm engine too)
You would use the water pump from a 2008-2014 wrx. They also have no oil cooler. Whole 08-14 wrx timing kit will actually be the same for your jdm 205
Thanks for confirming that. I took an educated guess and ordered a timing set and pump for a 09 wrx without the cooler lol. The only other thing I’m unsure about is the extra Pcv hoses since the new motor has 2 ports on each valve cover. Is it pretty easy to figure out just by looking at it? Is it similar to like a 04 USDM Sti? I can probably find a diagram for that.
@@agrif762 yes the pcv system will be same as 04 sti. What you can do is retain the jdm pcv system and if needing any parts/pipes for it later the 04 sti will have same routing
hey guys, im stuck on my swap currently because the alternator/AC bracket is different. did you struggle with this as well? or am I going to have to lose AC until I can get a shop to swap over my JDM compressor.
We always use all the domestic accessories on the jdm engine. Including domestic ac bracket intact with domestic ac pump along with PS pump. Jdm alternator can be used though without issue
@@TheSubieSanctuary I just got back to the car, and I think i see what you mean. So I should change all of them at the top, and then not have any issues!
Thanks for posting.. So I have a 2002 wrx looking to do the same thing.. I’m seeing other videos talking about the intake cam gear and crank sensor being switched. Is that necessary? And will the head hemorrhage oil not using the AVCs?
You do not need to swap those sensors, leaving the avcs untouched will not effect oil’ing. Its actually preferred vs trying to swap in non avcs gear and shaft, that is when you run into oil path issues.
@@TheSubieSanctuary thank you. The perspective on this topic has two sides. I guess I have to buy one and see what happens. I do appreciate your time and video on this topic. I would love to basically just drop it in like your vid. I’ll look into the JDM seller you recommended
@@MusicBitch603 if you get a jdm 205 with a drive by cable (throttle cable) you can actually just drop it right in the car without swapping manifold! Everything plugs in and no codes after.
However, the engine we used in the video was still a jdm 205 but it was a drive by wire throttle body, so we have to swap the whole intake manifold over due to different harness
@@TheSubieSanctuaryso if I get a jdm 205 drive by cable with AVCS do I just leave the sensor for it unplugged?
@@kokopuffz5841 correct! Everything will plug right in, dont even need to swap intake manifold
I just got both down to long block. I have a cannonball sized hole in the middle of the block that obliterated my coolant crossover on the usdm. Can’t find one anywhere lol
Ah damn, ya ive been in that situation before. May be pricey but you could try dealer.
Where about are you located? I probably have one i could mail if you cant find one
I’ve checked the dealers in my area with no luck. Only finding the jdm ones on eBay lol. I live in BC Canada on the west coast.
@@Heckbox im just in Ontario, if i have one which I probably do. I could mail it out . Do you use intsagram? If so pm me on there @the_subie_sanctuary
If not, you can email the.subie.sanctuary@gmail.com
You don’t have to swap cam gears ?
You do not have to swap cam gears, you can however if you want to swap cam gears to non avcs gears along with the cam seals. But it wont make a noticeable difference
So other than the motor what do I need to purchase to do this swap? I ordered a non avcs long block that is jdm
You might need lower intake manifold gaskets and coolant crossover o rings for the swap
@@TheSubieSanctuarycoo, this other guy was telling me I have to change my intake crankshaft pully and all the sensors this will be my first swap and I don’t know if I will have to do that
@@UGKsta you can compare them , just take timing covers off and it will be very easy to see if teeth are different on crank gear.
You can't convert a jdm ej20 to a usdm ej20 right?
You could for sure. Ideally you would also use the usdm ecu and you would have to reverse the avcs wiring to become tgv wiring
I’m about to buy a jdm ej205 and do this exact swap. Does it matter if the engine I buy is single avcs or normal avcs
There is non avcs, single avcs and duel avcs.
Only non avcs and single are going to work with the 02-05 wrx. Hope that helps
@@TheSubieSanctuary thank you I appreciate the help. So much information and so many different opinions on the internet it hard to find what I want sometimes lol
Hi Subi Sanctuary! I have gotten a jdm non avcs morter. Would i requier swapping the cam gears even tho its a non avcs morter but still and ej205? Any help is very much appericiated
If your putting non avcs 205 into usdm wrx 02-05 then you dont need to swap the gears.
Okay awesome great i was confused, its my first time doing the swap and it really helps to know. That i dont need to swap the gears. So its just the sensors i need to swap right?
@@officialjosemarin5806 if your jdm motor is a drive by “cable” which means mechanical throttle body. You actually dont need to swap the sensors. You can for piece of mind if youd like
Wow awesome thank you for all the help you give!
@@TheSubieSanctuary hey subie sanctuary! I have another question here after a year. Ive learned alot with my first jdm swap but now im moving onto my second, ive followed the same routine. But now ive ran into a different engine ej206. I beleive it was twin turbo. Ive blocked all the connections for the second turbo. But now im in a bind with the line that feeds oil to that second turbo on the drivers side. I managed to get the engine to run but i got oil puking out of that banjo bolt. Is there a way to remove the bolt without having to pull the timing covers and components?
did you use the usdm crank sprocket for this? i love watching this video but i never can tell if it was switched over
Sorry, this was an older vid and my explanation was a bit primitive then bs now on some stuff. Really need an updated vid. I did not swap crank or cam gears or sprockets.
Only reason you would ever have to us if you got a ej205 from a jdm gc8 (they have large spacing between crank sprocket teeth vs the 02-05 wrx’s with the close teeth on crank sprocket. Just compare your 2 to be sure. Only need to crank pulley off each and take a look
@@TheSubieSanctuary hey! I’m back so I’ve been starting it and it’s been giving me cyclinder misfires on all cyclinders and -2 boost pressure idk what’s up
@@roxythekrx7190 vac leak is very possible. Should be like -18 at idle.
As for the misfire, does it run like its missing on all 4.
Maybe coil plug plugs are backwards.
Black to the back for coil packs
@@TheSubieSanctuary the coils where a problem I switch them to the right pattern black in the back and for the vacuum leak yet to find it but apparently it’s a big one if it’s at -2 in boost
But after I switched the coil plugs it still does it
I know this video is a bit old. But did he not need to get a retune? From what I have read on the forums jdm and usdm ej205s have different compression ratios.
No worries, they are not different compression ratio’s. If out back exactly the way it was. It will not need a tune.
@@TheSubieSanctuary ok cool I have currently building a hybrid engine with a 257 short block and 205 heads but really miss driving the car so I thought about throw a jdm longblock in but then I realized I would still have to tune anyway as my fuel system has dramatically changed lol
@@TheBluntcreature ya the 2.5/2.0 combo is wicked. And ya thats a good point if you have mods already to consider when putting in the jdm for time being
@@TheSubieSanctuary yea had a buddy with one. I already have a bunch of mods
@@TheBluntcreature was your car already tuned for the mods? If so then just replacing the long block youd be fine as is. Unless they are new stuff since last pulling engine then ya youd need a tune ideally
So just leave the plugs for the avcs with nothing on them and the jdm cam gears can stay on the motor
Yes sir! Later if desired you can always add in the bulk head avcs harness with appropriate ecu.
@@TheSubieSanctuary but to the people who want to do avcs you will need to have a manual transmission to use this feature the automatic transmission will not allow it to work without catastrophic results
@@dakotaevans1768 an auto car can run avcs no problem as well. Just need single avcs ecu for AT , they are actually easier to find too
I have a question I did a jdm ej205 on my 1999 rs do you why is just cranking but won’t start
You running a wrx ecu and bulk head harness?
Yes usdm ecu and harness merged
Do you know what could be wrong there?
@@TheSubieSanctuarydo you know what could be happening there
@@juanjimenez-wl2kv did it run before with 205? Or this all new?
if i had to figure it out, id plug in a good scanner that can do live data and crank car and watch for signal like crank and cam.
If you already have confirmed you have fuel and spark, then maybe fuel lines backwards?
Do I need to swap ignition coils and spark plugs using usdm ECU?
No, the jdm uses same spark plugs as original ej205 as well as coil packs. Always wise to put in new spark plugs though while motor is out. Typically thr jdm coil packs will have less milage and if your jdm engine came with them id use them over the original ones.
@The Subie Sanctuary hmm the JDM use diamond FK0186, the usdm 02-03 uses Fk0333and and the 04-05 uses FK0334 Are they all the same? I know for sure they all use the same spark.plugs, but the ignition coil have different numbers.
@@AndemusRay the can have different dwell times which is minor and not an issue if you match and use an entire set.
@The Subie Sanctuary oh, good, good. I'm just trying to pinpoint why my blobeye is running rich at idle, I bought it recently, and the last owner told me that was a jdm swapped. I'm planning to send a tuner my cobb datalogs, but my brain never stops looking to fix and understand things.
@@TheSubieSanctuary thank you for your fast responses.
How come you didn’t have to switch the cam gear? Just asking because I’m in the middle of doing the swap myself right now and that’s what I’ve been worrying about this whole time
if you remove the jdm gear and usdm gear you will see they have the timing spurs in the exact same spots. The car wont know the difference. 100% do not have to switch the timing gear. That seems to be some weird bit of info on these.
Ive done 20+ of this exact same install. Never changed a timing gear.
Good to know. I noticed the crank sprocket was the same as the usdm one so it made me wonder if I even had to change the cam gear. Thank god I found this video now because I didn’t want to have to go through the hassle of taking off that weird looking cam gear on these lol
Darryl Torres ya i figured it would be helpful. Some much mis information on the net on how to do these.
Ok one last question what do you do with the extra coolant hoses that come from the jdm motor? Do you just cap them and put a hose clamp over them?
I’m sorry idk if there coolant hoses or breather hoses. But I’m talking about the extra hoses that are on the valve cover gaskets
So if i did all this and went with bigger injectors and vf48 turbo and tune would i be ok
Absolutely! Even if you used the pink sti injectors or the dark blue 255/257 injectors youd easily be able to hit 270-280whp after a tune
@@TheSubieSanctuary so I dont need to hook up the avcs
@TheSubieSanctuary what did you all do with the 4 valve cover breather holes that's the only thing left I need to do on my swap
@chasejustice8219 i used the jdm pcv routing/piping
@@TheSubieSanctuary where does that driver side rear valve cover hose go to
Hey guys I was wondering if I could get a list of everything to swap I’m currently stuck ordering parts that I may not even need but there’s so many different sources saying take this or that off but seems like you guys really know what is necessary
What model/year do you have? And what motor is going in?
@@TheSubieSanctuary I’m putting in a jdm 04 ej205 into my 04 wrx usdm
@@BrynnBadCompany ok, are you using your original ecu? If yes? Then you can swap just as we did in the video. Basically transfer over your intake manifold in 1 piece. If you want to use the jdm tgv deletes that will come on your jdm motor. Then you can swap those on as well. You will need the tgv codes turned off if so
@@TheSubieSanctuary it’s really that simple not water pump or anything?
@@BrynnBadCompany as for water pump. Some jdm ej205 if they came from manual car will have the oil cooler/warmer like your usdm 205.
If you want to use the oil cooler/warmer you can swap over water pump. If your original 205 suffered rod knock or piston break down. You will have to get a new oil cooler as they cant be used after engine failure.
Hey so I’m swapping the JDM engine into my usdm bugeye and the cam gear on the jdm engine is broken, i’m not sure if it was broken in shipping or what. But are the cam gears the same on the USDM and the JDM engine? a thank you guys so much for making this vid by the way
hey, 99% sure the cam gears are the exact same
They are the exact same “if” your jdm engine is non avcs. If your jdm engine is avcs, then it will have avcs intake gears. Before i go into detail, tell me if it was a top or bottom gear that broke!
Exh cam gears are the same regardless.
Glad the vid was helpful!
@@TheSubieSanctuary thanks for the reply, it was the bottom right cam gear
@@thatcherwalls389 ya that one the same 👌
woaah crazy the cam gear shattered holy shit she sounds good i almost puked when i saw it was an auto lmfao
I'm looking to swap a jdm ej205 into my auto 02 wrx and I've been confused about a couple of things.
So I will need to keep my intake manifold and swap it onto the jdm motor? Are there any other parts that you didnt show in the video that will need to be swapped?
Does it matter if the motor is automatic or manual? (Might be a stupid question, im new to cars)
I was looking at a motor that said DOHC Drive by Wire, are either of those things a problem?
Dohc drive by wire is the same engine we swapped in this video.
Simply swap over your entire intake manifold in 1 piece.
@@TheSubieSanctuary can you send me a video of the intake removal in one piece cuz that would save a lot of time next time lol
Doing this same swap into a silver 02 bugeye in mint condition just needs a heart but got a few snags
@@dakotaevans1768 its just the 8 long 12mm bolts through the tgv’s. Then unplug all the plugs, undo the pcv hoses that connect to manifold and engine.
Do you use block off plates for the avcs ? Our just leave the plugs open
Leave them open, they cant do anything without power to them
my motor is on the way im sooo nervous
Its not too bad to do it. Comment here with any questions
Thanks! what timing belt kit would you recommend? i was thinking IAG.@@TheSubieSanctuary
@Heckbox hey buddy! Some if the jdm 205’ have the oil cooler and some dont.
So depending on how yours comes you can use kits ordered for the following.
205 Without oil cooler (08-14 wrx)
205 With oil cooler (02-07 wrx)
I did all of this and my car is not turning on its struggling idk why
Crank but no start? Fuel lines backwards is a common on. Let me know!
@@TheSubieSanctuaryI forgot to replace the sensors from the usdm like the CRANCK sensor knock sensor and cam sensor
@@ANDREW1994ization if they plugged in, it won’t actually effect they are most often all the same sensor

@@ANDREW1994ization the engine cranks over right? But does not fire right?
PRNDL nightmare
Like I always say drop it in D
I didn't see you take out those cams
Ya exactly, its a myth that it’s necessary. Never swap the cams
@@TheSubieSanctuary most certainly not a myth
@@TheSubieSanctuary I'll bet anything you want on that
Mike Roshop ok, and why?
@@TheSubieSanctuary I mean the car will run, just not right
So if I get a jdm 205 I can run it without using the avcs without having any issues?
Absolutely!
