hey i have an 88 turbo supra and i yanked the motor (BHG) and i was considering a 1UZ to replace it out of and 94 lexus GS. now my qusetion is there anyone out there who has done this swap before? what things am i gonna need? how hard is it? you know stuff like that. i am gonna use the R-154 transmission. And honsetly should i not do this and go 1 or 2 JZ?
1UZ question
- Thread starter tbots
- Start date
There's a company that makes a V160 adapter plate for the 1UZ, which will also allow you to bolt an R154 with 1JZ bellhousing to the 1UZ. You will need to get a 7M or 1JZ flywheel drilled with the 1UZ bolt pattern, then use a 7M clutch and pressure plate.
You're going to be looking for an earlier 1UZ with a separate transmission ECU, or else you will have issues running it in front of the R154. Alternatively, you can bolt the 1UZ to the Supra's auto if you're into that sort of thing.
Motor mounts, will have to be custom, I'm not sure about the oil pan. the 1UZ came with all sorts of oil pans, you'll need to find the one that fits the A70. I believe SC400 ones work. There are a few 1UZ supras out there.

Go on youtube and do a quick search. I was looking up vids for my AE86/1UZ-FE swap and I found a bunch of info on the tranny swap and also a few vids of 1UZ's in Supra's. This site might be useful. http://supra.milisake.com/
the "project parts" area is pretty useful. Good luck to you

Well its a good thing then your info is barly correct.

There are much easyer ways to do this, that dont require sorcing a hard to find bellhousing.
annoyingrob;1225003 said:
First off, in the usa there was no seprate auto ecu, second the car runs fine with the single ecu with a manual trans, it accually doent even knotice when the auto transmission is missing.

yes the SC400 motor is the correct motor to use the GS400 didnt even exist untill 98.

Actually the bellhousing is not hard to find. Jeff Watson at Championship Toyota has them in stock, or at least did when I called to order mine. Was also the cheapest place I found a new 1JZ R154 bell housing at so I could use TTC Performance's adapter plates. BTW, Eric is the guy you want to talk with at TTC Performance if you go this route.
For the least amount of headaches, you'll want the SC400 engine. Has the sump in the correct location, tubular exhaust manifolds, and good location for the oil filter. I used the 1993 SC400 1UZ-FE ECU and have no issues running the engine with the R154 tranny. Also you won't want to redrill a 7M flywheel as suggested. Cheapest/safest way to go is I believe with the 3GS (Jake correct me if I'm wrong) flywheel since it already starts out with the 8-bolt pattern which only needs to be milled slightly to fit. The chamfer on the ring gear is also the opposite of what the 7M ring gear is since the start on the 1UZ comes at the ring gear from the opposite direction.
I'm the guy that owns http://1uzsupra.com, amongst other domains (points to a subdomain at http://supra.milisake.com since I have gobs of room on that domain instead of purchasing another hosting account). I also have a much more detailed parts list which includes prices, part numbers, and vendors purchased from in an Excel spreadsheet. Just haven't had the chance to upload it yet. Jake and Chris (cjsupra90) have also done this swap and are very knowledgable and were gracious enough to answer some of my questions during my build along with a couple of other members on Lextreme whom I either called directly or wrote to with questions.
Looking forward to making more improvements to the car both suspension-wise and force induction-wise but may be slow going as I need to buy a beater for the winter so my wife can have back the Escape, lol.
BTW, my build thread on here is at http://www.supramania.com/forums/showthread.php?t=58535
It is essentially a mirror of my project site although I have a few posts on the project site which never made it here since I didn't feel they were applicable or added to the build's knowledge base.

Im not sure if your saying what im about to but eh, the 3S starter sits over the transmission, so the ring gear is oppisite of both the 1uz and the 7m. although its been done often its not the best starting point for a flywheel, an 1988 - ? V6 toyota truck or 4 runner flywheel is the best bet, the bolt patten is much closer to the 1uz then the 3s is meaning less modifying to the holes hence safer, and the ring gear is already correct. but the offset is wrong so quite a bit needs to be machined off the backside of the flywheel but nothing a maching shop cant handle. I wouldnt try to modify a 7m flywheel, ring gear is wrong, converting from 6 bolt to 8 bolt would leave a flywheel i wouldnt trust past idle. on a 4ag. it wouldbt be balanced any more...
soon i might be makeing aluminum flywheels for the 1uz, im working on the details of that at the moment.

Thanks for the correction Jake. Knew I was kind of fuzzy on which flywheel it was but figured you'd have the correct information
What price range you looking at for the Al flywheels?
I bought my flywheel from Suprrunner over at Clublexus. It was 290 shipped. Much safer than drilling the 3SGTE flywheel.
Why is the bellhousing an issue? Phil Bradshaw (over on the Lextreme forums) makes adapter plates for the W58 and the R154. I think I paid 260 shipped from New Zealand for my W58 one. This uses the 1UZ auto bellhousing. You can use the stock R154 trans mount to get it all lined up for your engine mount measurements. I do not believe there is anyone out there that makes mounts for the pre 89 subframe.
As far as I know, using a manual trans with the stock ECU cuts down roughly 65% of the wiring. To reduce that further, get a 92-94 1UZ without TRAC.
The only 1UZ from a production car with a seperate trans controller is the Crown (if I remember correctly). You won't find them in the US, and probably the bulk of North America.

You are correct. Unless Chris (cjsupra90) has updated his inventory of fabricated parts, there is no one who is selling the pre-89 mounts yet. I designed my own and redrocco (Lextreme member as well) also designed his own.
On the note of wiring, not much really needs to be wired up if going with the manual trans. I've got a write-up for the pre-89 body on my site and build thread and there are enough notes out there from Jake and Chris for the '89+ bodies. Wiring is no less with or without the TRAC option on the engine (Mine has the TRAC option). Not sure you can even make it work without the auto trans but could be totally off base with that assumption.
Also, there are several of us on here that are also Lextreme members. Jake, Chris (cjsupra90), GT400, and I'm sure I'm missing a few others. Personally I did not know Phil Bradshaw was producing and selling adapters. I purchased everything for my conversion here in the States. BTW, also got my flywheel from Suprrunner as well, but in a group buy over on Lextreme.
Its a very good engine it weighs around 400lbs and its very cheap they could be found all day long for around $600
I am thinking of putting one in my 1997 4runner its a bolt on afair I have the V6 3.4ltr 5zfe with the a340 4x4 tranny the bellhousing, torque converter & input shaft/oil pump is diffrent but easy to swap out from what I hear.
I would highly recomend this engine for reliability, perfomance & weight.

Yeah Phil is a wealth of information, and he sells just about everything you would need. I know he does flywheels and clutches as well as adapters. He provided me with wiring diagrams for my SC and tips and tricks to overall make things go easier. Example - Using a 4 cylinder 86-89 Celica tach driver module to get the tach reading 4cyl pulses. Apparently it fits right on the back of our cluster...

I think this thread has expanded past being for tbots porposes.
All this talk of conversion parts. Im working hard at the moment on all the physical parts to put a 1uz with manual into a supra, mounts post and pre89, and also R154 and W58 adaptors and also aluminum flywheels
I will have the parts ready made and availble 1 click away on my website. no hunting and searching any more, im also working on having easyer to read wireing conversion info. that i will post on the site. so it will be a much easyer 1 stop location for 1uz supra swaps, if anyone is intrested in parts let me know, post 89 mounts and W58 adaptors are ready to ship now, only a few weeks on flywheels, R154 adaptors and pre 89 mounts.
