- SUBARU ENGINE GUIDE! In this video we go over the different types of Subaru engines as well as the characteristics to tell which one is which.
Which Subaru engine do I have? We know this seems like a silly question but a lot of engines are mislabeled and people sometimes purchase the incorrect engine for their project. We thought we would create a guide to distinguish which engines are which. Please note this is for EJ20 and EJ25 Turbo motors.
Check out our blog post for more details and the full engine guide - www.iwireservices.com/post/wh...

You either have the Subaru engine that either leaks oil, consumes oil, got starved for oil and/or blew the head gaskets .
Yep that’s why we’re here trying to find out which motor we need lol
Yep…….sadly
To be honest, I got lucky because I have an engine that doesn’t leak doesn’t drink and doesn’t starve
I got lucky. I have a 2014 wrx. I put 125,000 miles on it with 18psi boost. No issues. Mobil 1 oil change done at 3-5 k
Thank you Whitney, today for directing me to y'alls video. This really educated me about the EJ205 that I pulled from my 03 impreza WRX- and making sure that I had made the right purchase of another JDM EJ205 from JDM-CALIFORNIA. Definitely going to be buying the kit for the AVCS and ECU. And thanks to everybody from iWire.
Excellent video, very informative, thank you so much for taking the time to share this!!!👍🏼👍🏼👍🏼👍🏼😊😊😊😊
Thank you for this video! I damn near bought most likely the wrong engine. You guys rock
Thank you for the information. much appreciated.
Just got an 05 sti. Came from B7 S4 & the engine bay is way more busy. Want to learn how to work on it. Thanks for the info fellas
thanks for the class guys !
Thanks, Did still miss some engine configurations eg. the Non turbo EJ25 with single AVCS and coil pack on top (hard to find parts for as it only exists from japan what i get) so lots of replacement parts even though i had a spare engine still had to buy parts from subaru...if only i could of afforded to make it into a performance car but you buy a 2k engine figured last more than 5k kms before head gaskets went
Went through a engine builder frasier engines. Best buy ever. Engine runs great got 50k on it troublefree. No oil comsumption. MLS headgasket. They upgraded all the proned troubles.
Thanks you sir. That was alot of help.
Very good video my question is if i bring non turbo engine and use its head block to my turbo is there any problem? thanks.
FB25B here
I have a ej255b with burnt exhaust valves in cylinder 4.
How about pulling valve covers, torqueing the heads to minimum values prior to reassembly? I was maintaining these aluminum motors in the 70s. It was a 12k Mile requirement. Gaskets have improved, but far from perfect, and Ally has a greater thermal expansion ratio than the finest steels. That won't change.
Good to know those information sir because I had a bad experience from eBay in short they send us a totally junk engine burned ignition coil pack, lose compression totally,like asphalt engine oil no catalic converter wrong side connector to computer I don’t know what I’m doing now maybe I put now on junkyard sir thank you very much
Question I have a full 09 wrx hatch and a full 00 obs wagon had them both for a couple years and have been poking around at swapping the wrx engine into my Impreza but Im a lil puzzled lol. Will my body harness and ecu be a direct plug and play? I’ve been doing a bit of researching to see if anyone’s really done this swap and I found a couple forms but they all stop posting updates, I know that the ej255 is a CAN BUS and that my ej22 isn’t so it’ll be a “harder” swap than usual, I also read on your website that it would possibly need a stand alone ecu for the vehicle to properly run and have everything on my dash work accordingly but if I swap the entire car over will I be fine? I would love to hear that there is a way (hopefully an easy way) to get this swap done and if there is anything I should be looking into. Thank you
Hi ,i put jdm type Ra 1998 280 hp engine on my Subaru impreza 211 hp, but the temperature sensor (iat ) on air box filter was not connected. can you tell me which PIN of the ecu should I connect it to?
verry nice explain idol..
Having trouble finding the forester ej20 single turbo engine for 2004 model
Thanks for the awesome Video!
I have a 2005 USDM WRX that was swapped to a JDM EJ05 AVCS. I ordered the iWire AVCS Wiring kit intake/ bulkhead and ECU. the car runs and drives great! I'm having a hard time finding a diagram of which Cam sensor is which. I have a Check engine light for Camshaft Positing sensor 'B' Circuit bank 2! any help would be much appreciated.
Shoot us an email and we can try to help.
I have an 2002 Wrx Impreza and has sti badges and I’m in process of replacing or rebuilding the engine so I’m wondering if it’s a ej207 or ej205 because I can’t find a 2002 wrx sti
I must say, this is one damn good video. I'm glad I watched it. Do you know if the 1999 Subaru Impreza automatic engine would fit the 1997 Subaru Legacy Outback? I really would appreciate your info. and also your contact info. Thanks and Aloha!
It would fit but there would be differences due to the phase 1 and phase 2 differences. www.iwireservices.com/post/phase-1-vs-phase-2-subaru
Great video thank you. Can you help with IACV delete or tuning. I am sick of the engine revving when I want it to idle!
I’ve got the same issue with my 2001 FSTI revs really abnormally I’m sure some cleaners and replacing the flange that sits in there.
Thanks for the video my question 06 wrx with single avcs the donor motor ej20x has dual will it work if I dont use the bottom avcs
This should help - www.iwireservices.com/post/ej20x-and-ej20y-dual-avcs
Still can’t really see what motor I’ve Got? The motor at the kinda looks close
Mine is a ej22e in my 98 Legacy
Great video! I hope that you can help answer our question. We just had the engine replaced on our 2003 Forester 2.5xs. after the previous one failed. The mechanic said he had a "donor engine" from a car that had rolled over. Since the swap was made, the motor seems to have less power and shifts more often when going uphill. We did some research and wanted to make sure that an engine with the same power was installed. The previous engine, from the VIN plate, was EJ25 IBXUAB, the swap has EJ25 on one side and C218957 on the other side. Could you share your opinion on the similarity of the swap or at least confirm that the donor engine wasn't an older or inferior swap, thanks!
You'll need to make sure it was a compatible long block with your original engine and that everything was installed properly when new engine was put in. Here's a link to our blog post about replacement long blocks - iwireusa.com/blogs/iwire-university/my-subaru-engine-blew-up-what-should-i-replace-it-with
@@iwiresubaruwiringsolutions5538 , thank you for your quick reply, we'll investigate.
Hey do you guys have any videos on the FB25? I need a replacement engine for my '13 legacy. I've began the process of getting another 2.5l for her, but this sensor wire thing you highlighted got me wondering if that's something I need to be watching out for too, or is it just with the WRX
@@vanzypubg8469 Unfortunately we do not. Usually the non turbo applications have fewer differences.
Mine was a three wire running Zero wire
How i do to wiring my dual avcs my engine have 2 each side the ones from the exhaust is unplug and doesn't have the wires

Hi can I ask a question about putting my engine from 04 EJ20 blobeye wrx 225 to a hawkeye I've been told I can do it but I might/will need to sort the head light wiring for the lights to work
We would not recommend this.

Quick question is it true that we need to swap over some usdm parts over to the jdm engine?
Many of them do depending on which engine you are talking about. Some you want to swap over and other you don't need to or want to.
So if it’s signal avcs
It will have 2 solenoides,
One each on the intake sides?
Hi Irvin, Here is a blog post with more details that will answer your question - www.iwireservices.com/post/which-subaru-engine-do-i-have
Great video and spreadsheets included in description. I have a 2008 wrx sti hatchback and I need a new engine. Would a 2005 OutbackXT motor work. Differences i see: OB is EJ255 with single AVCS and plastic intake manifold. Are those show stoppers? thank you!
This blog post on engine replacement should help answer your questions - iwireusa.com/blogs/iwire-university/my-subaru-engine-blew-up-what-should-i-replace-it-with
@@iwiresubaruwiringsolutions5538 Thank you for responding. I did read that blog and i'm still a bit confused. I am looking into purchasing an '08 sti but it currently has a non-turbo motor in it. I have asked the owner to see what specific engine is in there now. Do you foresee any major issues that they would have had to do to put a non-turbo in an "08 sti correctly? the blog mostly talks about going from turbo to turbo engine or from non turbo to turbo. It doesnt really talk about going from turbo to non turbo. thanks for any help you can provide!
@@Colin-uz4lm You're very welcome. I do forsee some major issues with the non turbo in the 08 STI. Which ECU is used, does the DCCD/Trans still work, which crossmember is in the car. Our general recommendation is to try not to purchase someones project car since there are usually issues from the previous owner.
@@Colin-uz4lm Yes, if there is a non-turbo engine in there this would require some serious modification to do so. Please send us an email to info@iwireusa.com so we can discuss this further.
my ej20 dont have a wire for the throttle body. coil on plug. plastic manifold
It sounds like you have an EJ20X/Y. We have a blog post for more details: iwireusa.com/blogs/iwire-university/ej20x-and-ej20y-dual-avcs?_pos=4&_sid=6570ed5a1&_ss=r
Hi. I'm doing a 2010 legacy gt ej255 swap with a JDM engine. I just got the exact replacement, but it's from an automatic. Will this need changes ?
The engine between the auto and manual models are the same so that should not be an issue.
Hey i have a 06 wrx, before i bought it he said he did a motor swap an a egr delete but he just welded a tube to the air valve to the down pipe thinking it was a egr ive removed it but im not sure if he bought it off of ebay or just used the air valve that came with the car, its a ej25 an theres no plates or places to put block off plates under the turbo or on the drivers side im just stumped i can send a video of what it looked like before i removed the air valve if you have any social medias
Hi, We'd recommend taking it to a local Subaru shop so they can verify what's been done.
Ok so i have a usdm 04 wrx manual with a blown engine. I live in the bahamas so we have rhd imported subarus. I found a 08 subaru exiga gt which has the ej20x/y but its a auto. How hard of a swap would that be?
short answer - it will be a very difficult swap. Send us an email if you'd like more specifics
I am new to subaru and long story short. My wife's dream car was 2006 subaru legacy wagon. We found one basically 1 owner and 113k miles. Test drive and look over was amazing and carfax was clean. Well...... 200 miles later went to do oil change headgasket was bad. $1700 in parts and labor later went ahead and did wp and timing at same time. We received car back from trusted mechanic. We drove it back and forth on family vacation ran amazing. It has been about 1400 miles since that and spun a rod bearing. My question is what years and model can I look for to be a direct swap? It is expensive to look at just the 06 to 07 and try and fine a reliable used engine. Trying not to wipe out savings completely out but my wife misses her baby. Any thoughts to help me.
Our* also what are the differences when doing a jdm swap? I haven't found to many videos on that vs articles to read about it.
Easiest thing to do is replace the long block - www.iwireservices.com/post/my-subaru-engine-blew-up-what-should-i-replace-it-with
I have a damaged 2011 outback EJ25 engine. I can take an EJ25 engine of any year out of the junkyard and put it in my car, it doesn't affect that it's from older years.
As long as you get a similar long block and keep the wiring intact that is correct - iwireusa.com/blogs/iwire-university/my-subaru-engine-blew-up-what-should-i-replace-it-with
@@iwiresubaruwiringsolutions5538 Hello, but when I was buying the engine I found that there is one with spark plug wires and another without wires, only with a coil. I have the one with only a coil. Should I buy the same one? Or if I buy one with spark plug wires, I can adapt my coils to the head cover, I doubt they will work or I will have problems with the electrical
@@luiscampos3688 Give a read to the blog post we linked before. It's generally best to replace with the same type of long block.
How do I tell the difference from a 207 from a 205 just by looking at the engine bay?
The 207 is a STi and the 205 is a WRX. We recommend looking at the ECU code to see if it's an STi or WRX. There isn't a great way to tell just from looking at the engine between those two.
For those two big harness plugs that you showed on the left side, which ones are those on your website? Cause on the motor that I recently purchased, the plastics housings of those two are cracked.
Brown one is - www.iwireservices.com/product-page/99-06-main-engine-receptacle-a
Black on is - www.iwireservices.com/product-page/99-06-main-engine-receptacle-b
We have the matching plug side as well if needed.
@@iwiresubaruwiringsolutions5538 Thanks!
what did you mean by the very last thing you said? remove any components on top prior to installing the engine.
It just means do all of the refresh/repair on the engine before mounting it into the chassis. Much easier to do when it's not in the car.
Will a non turbo EJ25 block work with Z25 heads? It’s for a cali U5 legacy.
Most likely, assuming a platform with without AVLS, but you would need to consult an engine builder to make sure the specs are the same.
Hello,
I have a 2017 Subaru outback and according to the VIN# i have what they refer to is a U5 engine what kind of engine is that?
A 2017 Outback would come with a FB25 engine as the general code assuming it's not a 6-cylinder Outback.
Hey guys , how do I check the year of manufacture of my engine?
How to know if I’m buying a 2005 2.0 thinking is a 2015 (years as example)
You would have to use the features on the engine. More about that in this link (scroll to the bottom for NA applications).

can you use short block ej205 on an ej20 b4 be twin turbo?
Short blocks are generally interchangeable if you confirm the combustion chamber specs work. It would be best to reach out to an engine builder about that.
Which of these would work best in a sandrail/dune buggy 2 seater and what other components besides transmission what would I need to get it running and is a wiring harness necessary if going on a sandrail/dune buggy
We'd suggest an engine that works with this wiring harness - www.iwireservices.com/product-page/standard-2-0-wrx-and-2-0-sti-wiring-harness
@@iwiresubaruwiringsolutions5538 appreciate the video thanks
Stupid question here what os a body harness ?? Is it the wiring loom that’s in the engine bay ?
The wiring loom in the engine bay is the intake manifold harness. The body harness is also called the bulkhead harness. It's the large harness behind the dash.
i have a ej253 engine will a ej20 bold straight into a sg forester?
It will not. More info about that here - iwireusa.com/blogs/iwire-university/my-subaru-engine-blew-up-what-should-i-replace-it-with
Hi guys, are the EJ20 engines (euro spec more specifically, but I reckon EJ20 is EJ20) prone to head gasket leaks like the NA EJ25?
It tends to not have as many issues as that the 2.5 but this isn't our area of expertise.
@@iwiresubaruwiringsolutions5538 I appreciate you getting back to me with an answer. Cheers!!
I actually need some help. I swapped in a motor. Jdm harness. Motor does not wanna turn over

Quick question, is there a difference in Transmission between the 2006&2007 Subaru wrx?
Thank y'all
There should not be.
@@iwiresubaruwiringsolutions5538 ok thank you for replying!!!
Hello friends, greetings from Zacatecas Mexico! I have a subaru legacy gt 2.5 2005 (ej25) but I broke the engine, right now I am doing an engine change for a wrx sti 2004 (ej20), I made the mistake of buying it since my subaru originally came with 2 position sensors 3 wire camshaft and this engine we are finding a 2 wire camshaft sensor! Can this problem be solved by putting your computer and the wiring of the wrx sti? Is the bsm or computer compatible with the rest of the subaru legacy equipment? First of all, Thanks
Thanks for your comment. We do not know of a solution due to the camshaft sensor difference. More about this can be found below.
iwireusa.com/blogs/iwire-university/subaru-camshaft-cable-throttle-vs-drive-by-wire?_pos=3&_sid=bf9609d38&_ss=r
A ECU swap is going to cause more problems than solve since you have a Legacy GT that is CANbus equipped.
iwireusa.com/blogs/iwire-university/canbus-part-2-can-bus-and-your-subaru-swap?_pos=3&_sid=15e022571&_ss=r
How would I be able to tell if the engine came off of a wrx or a sti
For US it would have different camshafts and you could use the chart. For JDM Red manifold for STI and Silver manifold for WRX
Unless you swap out the ECM and harness.
Rule of thumb for any Subaru project is you want an ECU and harness that match your engine.
Is there a big difference from a 02 -05 ej253 sohc non turbo and 07 ej253 sohc non turbo? Its for a 07 forester, just wondering if the 02-05 will work on it
if the throttle body type, AVCS type, Camshaft sensor type, ignition type, and manifold type are all the same for both engines, then the long blocks would be compatible.
@@iwiresubaruwiringsolutions5538 thank you for responding quickly, its a big difference in price , ill look for all those details, thanks again
I need to replace an engine in my 2012 forrester 2.5 L premium and I'm not sure if it's dohc or sohc
It will be DOHC
@@iwiresubaruwiringsolutions5538 hmm the carfax report says sohc.. that's why I'm confused about which one to order
But how you know you're buying a head and block only that's a turbo block or non turbo
You should still be able to tell generally if it would work with your application based on the AVCS and cam position sensor type.
If I have 2 wire coils can I fit 3 wire coil
You can not. Here's some more info on why they are not compatible - iwireusa.com/blogs/iwire-university/subaru-camshaft-cable-throttle-vs-drive-by-wire
Is it easier when I just talk about the year and model to let ppl know the engine?
Yes, 100% easier to go by year and model
What about the ej208?
Those are twin turbo models so fairly easy to spot. We do not recommend them for few reasons you can find here iwireusa.com/blogs/iwire-university/twin-turbo-engine-subaru-swap?_pos=1&_sid=6b73f24ac&_ss=r
How much would it cost for dash loom for ej20 with ecu have engine loom and do u have phone number

coool
Subaru motors are a cluster fuck of a time bomb.
If it's 2L it ej20 and if it's 2.5L it's ej25.
Yes, from a basic standpoint, you are correct. But that doesn't define what type or any other important characteristics.
@@iwiresubaruwiringsolutions5538 Actually very true. I have an ej201 and I need to replace it with an ej205 so I can do anything.
