- I figured I would throw up a video with information on the 1uz engine swap I did into my 91 Toyota pickup.
A few things I forgot to mention in the video:
- I wired it myself, with two fsm to reference its surprisingly straight forward to wire.
- I also did a idle up valve delete on the power steering pump
- Ac compressor delete
-the clutch is a marlin crawler hd clutch kit for the 3.0 v6 I had to use a 3.4 throwout bearing.
- flywheel is a machined and re drilled 3.0 flywheeI got from northwest toys.
- exhaust is 2.25" mandrel bent from the headers into a 2.5" mandrel bent tailpipe, all stainless and tig welded.
- oil filter adapter is from a 99 land cruiser with a 4.7 v8, uses the same internal o ring as the 1uz
Feel free to post questions, I will try to respond. - Auta a dopravní prostředky
I can not thank you enough for making this video. You have no idea how much this has helped me with my 1uz swap in my blue extra cab 94'. I must have watched this video 100 times. Thank you, Sir!!
I’m glad you got some useful information from this video. I was going to do a video on wiring but life gets in the way haha. I’m just happy I could shed some light on this swap for the community!
great video dude , this is the swap im looking into so this was super helpful
Just an update. The truck had been undergoing a major transformation over the last year and a half. The frame and suspension have been completely restored and I’m just working on painting the truck. Look for an update video soon!
Updates?? Please check my comment on the r154 flywheel mating, eager for details
TheRumbles13 I posted a reply to your question.
I will make an update video shortly. The truck is finally on the road again, just got 300miles on her so far
@@Jay351 Any update?
@@andrewo8987 I actually just put licence plates back on the truck last week. Just waiting for some nice weather. Look for an update soon, it’s a totally different truck now.
@@andrewo8987 just posted an updated short video. Gives a nice visual of how the truck sits today.
This is so sweet I’d rather do this than the 3.4
My thoughts exactly if you're gonna spend that much money.
That's a cool swap! I have been thinking of putting a 1UZ into my Gen2 Surf.
Man, Your truck sounds so good!
Nice job, sounds sweet 👍👍👍
Super nice build man.
Good work man wish you lots of smiles per miles
MrDonkeyoti thanks! I'm currently redoing the steering system, adding the rear o2 sensors in and re sealing the oil pan. Hopefully I can finish this truck next year
This looks OEM besides the blue intake but everything else looks great
Awesome.. I have a 90 Toyota V6 4X4 and a 00 LS400...hmm.... ha. Sweet build. The coolest Toyota truck ever with the best Toyota V8 ever made doesn’t get much better than that!!
I been waiting for this.
TheKoppenhaffer it's got a long way to go. Now it's suspension and body work...
Blazeland with a TC idler arm is what I'd do if I still had a pre-taco IFS. Can't believe I've been watching this build since I was in high school and on Yotatech.
TheKoppenhaffer that's still the plan eventually. I'm not totally apposed to sfa but I don't want leaf springs on the front. I want this truck to be comfortable on the hwy as some of our spots take a few hours to get to the trail heads..
Leafs are great for crawling and they are easy to install, but they suck for everything else. The backcountry roads I travel on are all covered with washboards. I have to severely reuce speed to avoid pounding myself and my truck to pieces thanks to the leaf springs in the front. The solution I’m looking at is a solid front axle with coil springs. That, and 63” Chevy leafs in the back. These guy have the best coil solution, but it aint cheap. www.4wheelunderground.com
Awesome truck bro
I have a 99 4runner with same swap... fkn beast
Mike Gray thanks!!
I didnt know 2UZ-FE headers fit 1UZ-FE no modifcations needed is straight bolt kn even the gasket i saw the headers sell for a good price tired of running stock ones lol awesome truck by the way !
TheEDD yeah they fit pretty good, except the first
drivers side primary runner needs to be re routed to clear the steering shaft.
Make sure you get 00-04 2uz headers as 05 and up use a secondary air injection system.
Also make sure you get thicker gaskets for the manifold to the heads, the eBay header flange is not perfect and will leak with a thin metal style gasket.
old video but you did an amazing job man!
91 hilux surf 1uz going in soon !
Many thanks. Have fun doing the swap!
what are the dimensions of the radiator? sweet truck! any updates?
What did u have to do to swap it, in terms of mounts and/or does it mate to the transmission without issues
Super helpful video thanks for posting. Did the front bumper mounts HAVE to be cut and moved or just an option for you?
The front bumper had to be moved forward to run my radiator in it’s current position.
You could do a few things to eliminate the issue with clearance:
1: move engine back another 1.5”, this may cause some grief with access to bellhousing bolts and shifter location.
2: run a pusher fan setup instead of a puller, then the rad could sit in the original position.
3. Smaller radiator, could be a good option depending on ambient temps of your area and how you use the vehicle. ( it gets up to 40c here and I beat the snot out of the truck)
4: mount the cooling system in the bed. I would probably do this. The engine bay is tight, getting good airflow is an issue, even with a body lift and a tube bumper.
If the rad is in the bed it’s protected and you will at least double the coolant capacity of the system. This kinda wrecks the “daily drivers” aspect if that’s what you’re after.
@@Jay351 thanks for the info. Amazing work!
Incredible
Holy shit how did u find where to put the mounting brackets
Interesting !! Brother I’m thinking of 1uz swap on my K5 GMC blazer any ideas how should I mate a 4x4 with this engine ?
Sanaan Jamali you would need to adapt the engine to your transmission/transfer case of choice.
You could use the factory automatic and use an adapter to install a transfercase. I think inchworm makes that adapter
What did you do for a fuel pump? I understand that Lexus had a two-speed pump in the LS400.
WrenchTech Unlimited stock fuel pump from the 3.0 is enough to feed the 1uz. On my 91 the circuit opening relay just needed a negative trigger to energize it. I used one of the ecu outputs to trigger a relay to supply negative to the c.o.r.
What kind of transmission r u using for
the ls400
How strong is the factory R150? Thinking about doing a V8/manual trans swap in my 94 land cruiser and I’m debating between the R150(easy to mate) or the nv4500(stronger)
I hear they are good for around 450hp. I’ve beaten the snot outa mine and she’s still good. Fresh shifter bushings from marlin crawler are a must!
Where did you get the radiator from? I'm doing the same engine in my 2 wheel drive 86
chuck blankenship northwest toys
which ECU output did you use for the negative/ground trigger for the fuel pump?
Angelo Ortega I used the mrel trigger and used a relay to provide a switched ground for the fuel pump. Not perfect as it won’t cut off the fuel in the event of an accident. But it’s functional.
Can you do a vid about wiring it up to your truck please?
I may upload some wiring info, but realistically it’s super straight forward. Even easier if you get an engine of similar year to swap in. E.g 89-92 pickup and a 90-92 1uzfe share similar systems for their circuit opening relay and such.
Buy a factory service manual for both vehicles, then you really only need to actually splice about a dozen wires from the truck harness to the 1uzfe computer.
Things like constant 12v, switched 12v, ignition, injector power stuff like that. The factory 3.0 fuel system is triggered by a switched ground that’s made by the Vafm. So I used the mrel terminal from the 1uz computer to fire a relay which provided ground to the circuit opening relay which would enable the fuel pump.
If you’re interested in doing the wiring yourself you really should have some experience with wiring and electrical. Otherwise it’s best to pay someone or buy a swap harness
Niiice!
very clean build! 👌 what are the dimensions of radiator? i’m basically doing the same swap but i’m using a 2uz. cheers 🍻
Sorry for the late reply. My truck has been moved to long term storage. When I get out there I’ll take some measurements. I did buy the radiator from North West Toys out of Oregon, they might have the dimensions listed on their site.
Do you have a list of items that you needed to do to fit the 1uz in to the truck? It would be great help if you can share it.
I don’t have a list per say, but within the video I’m pretty sure I’ve gotten all the items. Anything I missed I added in the video description. With the exception of the wiring, I’m no professional, the way I wired it may differ from others.
If you have any specific questions throw them my way.
What type of fuel pump did you use? In-tank or external? And the bars/psi
I used the factory spec denso replacement 3vze fuel pump. It is sufficient for the 1uzfe in stock form.
Seems only parts you need fabricated are the motor mounts and a way to mount it to the trans. The rest you can pretty much rig up yourself?
Devin Paulsen the rad required heavy modification of the rad support to allow space, along with removal of the hood latch.
Exhaust manifolds were modified (drivers side more so) along with a fully custom exhaust the whole way back.
Engine swap required a body lift so there’s modifications that come with that as well.
It depends how handy and mechanically inclined you are. I purchased the major bits like engine mounts, bellhousing adapter, but the more you make yourself the better.
Good job..
Great job! Very impressive build. I am interested in a 1UZ conversion for my 93 5spd 4WD Toyota T100. Any advise on the conversion for the transmission/bell housing?
If you use the KS racing bellhousing adapter:
Cut down the mount for the slave cylinder about 1.25” as it’s cast far to tall. You will need to cut the threads deeper for the slave mounting bolts.
The kit comes with the short input shaft adapter for early r150f transmissions. I used it with my 91 gearbox.
I used the flywheel from northwest toys (their first version), HD 3vze clutch kit from marlin crawler was used, but I had to use a 3.4L release bearing to make it all work.
@@Jay351 thank you! I am sourcing a 92LS 400 for this project. A lot of interlocks and deleted for security on this engine management system I see. Ignition key is coded. Guessing the wiring for this is detailed
@@brianlindsey1997 thankfully the on-board immobilizer is attached to the car, not the engine/ecu.
There was no need to bypass anything in that regard. As long as the ecu is powered up, Ignition system is on, fuel pump (through the circuit opening relay) is running. She will fire.
@@Jay351 excellent man, thank you for your help
Any more info on the flywheel and clutch setup?
R154?
Flywheel is a modified 3.0 unit. Clocked and re drilled for the 1uz bolt pattern.
Clutch is a marlin crawler hd kit for the 3.0v6 and I used a 3.4v6 throw out bearing
Input bearing came with the ks racing bellhousing adapter kit.
Stock r150 with the chain driven transfercase. Recently threw in a lce engineering short shifter.
Your breather filter on the driver's side valve cover needs to be removed and just run a hose to the intake somewhere as long as it is after the MAF sensor. The way you have it is basically just a huge vacuum leak through the crankcase. I did the same thing at first and was puzzled by my poor fuel economy (~10mpg) yet no check engine light and the ECU still compensated just fine at idle. Fixed it and I was getting 20mpg with 31" tires and 4.56 gears. Great video and such a fun truck to drive!
Jireh Ward interesting theory. From what I understand this is a positive crank case vent, it shouldn't really effect vacuum at.
I only deleted it because it's a high mileage engine and the condition was questionable. So I removed it to prevent any intake sludge.
But I'll try swapping it over and see if I notice a difference. Thanks!
I am getting close to doing this to my 1993 extra cab. So you used the LS400 oil pan? I am probably going to use the same bell housing. What did you do for a flywheel, clutch, clutch fork and throw out bearing?
Matt S_. I used the stock ls400 pan.
As for clutch/trans I used ks racing bellhousing. A modified 3.0 flywheel (new bolt pattern drilled into it), used a marlin crawler HD 3.0 clutch kit with a 3.4l throw out bearing.
Ks racing bellhousing needs around 1.5” cut off the slave cylinder mount and the holes re-tapped.
Thanks for replying so quickly. Some folks are saying that the 3VZE flywheel is too light. Have you noticed any issues related to that? Also, which fork did you use and do the 1uz engines have a spot for a pilot bearing.
Matt S_. I haven’t had any issue with the flywheel being too light. The flywheel I got from north west toys is just a stock replacement.
I used the stock release fork. I used the pilot bearing, pilot bearing spacer and Input shaft extension that came with the ks racing bellhousing.
So I take it then that the 1uz crankshaft has a recess in the end for a pilot bearing?
Here's a shot of my truck. It's a 93 with that presently has only 113,000 miles on it? wrenchtech.com/wp-content/uploads/2017/08/93_Toyota_pu-e1529390878161.jpg
I can get my hands on a KS bellhousing, but it comes with nothing else. I'll have to put the rest of the clutch kit together myself. And I may need the input shaft extension and pilot bearing.. I am hoping that I can get the extension made locally and figure out which bearing I should buy
WrenchTech Unlimited nice truck! Looks super clean, nice candidate for the swap!
I wish I kept records of which pilot bearing came with the kit but alas I did not. I actually bought the Ks kit locally about 3 years before I actually did the swap from a fella that decided to not use it. I did have to use the stock 1uzfe flexplate spacer behind the flywheel to ensure proper engagement of the starter. Nobody seems to mention that...
Does the 3.0 transmission marry to the engine just fine or what’s up
DADDY_ JULZ I used a ks racing bellhousing adapter. A 3vze hd clutch with a 5vzfe throwout bearing. Seems to handle the power of the 1uz without issue.
Do you know if the auto tranny A340F would bolt on to the 1uz?
No, bellhousing is not the same.
Most guys will use the stock Lexus automatic and use the inchworm output shaft adapter so you can bolt on your transfercase.
could you mount this 1UZFE engine to a 6 speed manual transmission, say from my 2006 ?
Daniel Borrer you could mate this to just about any transmission depending if you can either buy or make your own adapter. Thankfully the r150f is a popular trans to use so conversion parts are easy to get
Jay351 thank you for the reply. I am just starting to explore the idea of this motor swap and wondered how the 1UZFE would do (perform) with my existing transmission. I'd think that the increased power would be detrimental because the existing 6speed (I'm not sure of its technical name) was not engineered to withstand this much power.... I understand of course depending on how the user drives the vehicle would play a big part of the longevity of the paring....
thanks-
Daniel Borrer the original trans in my truck was designed for a v6 with around 150hp. It handles the 1uzfe no problem, and I beat the snot out of it! Its never given me issues even shifting at full redline full throttle!
Is it possible to do this swap without moving the radiator and losing the A/C?
Matt S_. Yes. you can get the engine back father by massaging the firewall and shifter openings.
If I did it again I would set it father back to avoid the rad clearance issues. That and solid mount it no rubber bushings!
The place I got my rad from sells an ac condenser to bolt on so it is possible to have working ac.
@@Jay351 curious as to why you would skip the rubber bushings and mount it solid? Thanks for your video.
Ben Brunson well my truck is just a toy. So I figure the vibrations you experience are worth the rigidity of solid mounting.
I had to drill through the motor mounts and install a bolt to prevent so much flexing of the engine under torque. It works but I think either an upgraded engine mount or solid is the way to go.
Based on your other videos, it looks like you're on the lower mainland. If you ever get over to the island, I'd love to take a peek at the truck. I have a '93 that I would love to do a 4.0 swap into.
RideVictoria too bad, I was actually over on the island, with the truck last weekend!
Jay351 😃
I have a 93 LS400 1UZ as well and do you know where the Igniters and Injector/Sensor power wires are located in the harness? Are they in the same plug as the Starter signal wire?
Should be located in plug iL1, wire is black with orange tracer, feeds the injector circuit. If I remember correctly it also feeds the ignition coils. Been many years since I did the wiring on this swap. Same plug as starter trigger wire.
@@Jay351 awesome I see there’s 1 Black/Red wire? I assume that’s power to the Sensor wires?
@@cakebop the manual shows it as black/orange but it may be more red than orange.
It should provide power to both ignition coils and all 8 injectors. You could use a multi meter to check the wire in question, using one probe at the ecu end and one probe out at each injector and coil, using the ohm/continuity function on the multi meter.
@@Jay351 yeah there’s one Black/Orange wire and one Black/Red wire in the same iL1 plug
@@cakebop the black/red should fed from 15amp supply. This supplies various sensors with their 12v power such as o2 sensors, idle up VSV, egr system etc.
What did you do for mounts?
Daniel B. Got the mounts from northwest toys llc. I used factory 3.0 rubber mounts along with those
What’s your pilot bearing setup? Adapter needed?
Pilot bearing came with the KS racing bellhousing. I will try to look through old pictures to find a part number.
I did have to use the included pilot bearing spacer in addition to the input shaft extension for my short snout r150f trans.
I'm not sure if you remember what did you do for the wiring?
Wiring is fairly straight forward. If you have access to the Toyota schematics you pretty much just Match up the wiring.
Things like constant power, switched power, ignition/injector power, starter signal. You will need to splice in connections for oil pressure, water temp sensor. The 1uz uses a dual speed fuel pump, the 3vze used the air flow meter to give ground signal to the circuit opening relay to allow the fuel pump to run. So I used a spare output from the 1uz ecu to trigger the circuit opening relay. You will also need to separate the 4wd front differential wiring from the old engine harness if you’re working on a 4wd truck.
Toyota is pretty consistent when it comes to wiring. The lion share of the wiring is from the engine to the ecu which you don’t need to mess with. Remove as much old wiring for the transmission and other items like egr if you don’t plan on using them.
@@Jay351 awesome thank you thats a huge help
Did you find a swap guide for this ?
No complete swap guides for free out there. All the Info needed is available if you do the homework.
🍻🍻🍻
We’re you able to keep AC and PS?
The nwt mounts allowed the shifter to stay in oem place?
How has that w56 held up?
Stone Chief trans is the original r150f. No issues with the increase in power. I only put a few thousand miles on the truck before I tore it back down for a semi restoration.
how can I do this and how much will it cost me?
Skim Broskie it depends how much you can do yourself. If you’re a good fabricator and have all the tools you could do this swap for under a few grand. I lost track of the total cost years ago.
can u do a little video about the wiring .I have a 1990 4runner and a 1992 Lexus v8 with wire harness . that's about the only part I'm a little worried about . thanks by the way that's a nice swap you got there.
fredy mejia I'll try to make a video about some of the wiring.
It's really not that bad. You will have a slightly more simple swap compared to me. The wiring tends to change in the 92-93 year changeover for both Vehicles.
Don't be scared, just buy a factory wiring manual for both cars and go one wire at a time.
Hey just a quick question what you do with transmission I have several Toyotas and have been dreaming of doing V8 swap and doing all Toyota but have not found a whole lot on swapping over to a 4 x 4 5 speed what did you do and where did you get the kit please get back to me I would love to do the swap soon thanks looks good though love second gen Yoda's with big Power
i would like to ask u about ur 1992 lexus V8
Does the 4x4 work?
Sure does!
Can you get me wiring diagrams
ALWLEED 506 I purchased the oem wiring diagram manuals for my 91 pickup and the 93 ls400 from eBay. I wanted paper hard copies rather then electronic copies. Then I just layed then out next to each other and matched up most of the wiring, like injector power, ignition power, etc.
I had to do some creative wiring to trigger the factory circuit opening relay but I also configured a kill switch into this circuit to make stealing the truck much more difficult
WTH IS ZED OR DO YOU MEAN Z.
