1UZFE into S-Chassis

[Marphie21]

So what are the confirmed final drive ratios that work best for the swap?

Something mildly long, like the 3.9?

We're trying to figure it out right now with our set up: Rb25DET transmission and 195/55 R15 tires

[Clutch Dog]

15 inch tires on a 1uz?........ lol thats a nice idea


stick with stock gearing and change it depending on what you need it for. alotta guys keep the gearing for mad skids

[Marphie21]

Stock meaning 3.9?

The whole set up is going on a KE70 corolla chassis. Aside from the RB trans, we're swapping an S-chassis underneath the Corolla body; S13 subframes front and rear.

I just need something that wont bog down in 3rd. We're only using 280 treadwear tires though, if that helps. Grippiest tires we'd ever put on the car would probably be Achilles 123S, if the set-up can handle it.

Anyone have any problems with clutch engagement? I can't seem to get the car into gear with it on the ground, I assume my throwout isn't making contact with my pressure plate. I have the collins extended throwout bearing so I couldn't imagine how this is possible?

Which trans are you using?

I'm using a z33 trans but I had a similar issue with the throw out bearing. There was another spacer on my TOB adapter that I had to remove because it was spaced out to far. I don't know if he got mixed up during packaging or what but you may have something similar coming on. You got a pic of the adapter you have?

[Turb]

My throw bearing adapter is just an extended throwout, its the old brett collins welded two throwouts together lol.
There's a really good close up picture of it in this thread on page 26.
Thanks again!

[Turb]

It's almost the same situation as badass8 was in, but I cant imagine my clutch disc is getting stuck on my pressure plate as the clutch and pressure plate all came with the collins kit!

This is completely worthless but it's funny to see people mentioning Brett Collins on this forum.

He's a good guy, lived right by him and felt with him a lot buying Nisan flywheels from my work to modify

[Turb]

anyone have any input to a exhaust on the 1uz?
I want the car to be loud but quite enough I don't get the cops called on me for driving down the street, right now Im just running open headers so its ridiculously loud.
I was thinking of running a 3 inch y pipe to a 3inch stainless to a straight through muffler in the middle then 3 inch stainless out the back.

What do you guys think? I want to quite down the car without sacrificing performance.

[1UZVillain]

I got my engine, it looks brand new to tell you the truth. 1uzfe vvti, guy said it has 30k+ miles.


Should I go ahead and do the swap or wait to fix the ECU issue. im going to start cleaning the transmission and prepping it, and replacing the starter/knife edge it

[1UZVillain]

any info on the bellhousing slot you have to cut out? pictures? im a visual man.

My setup is modified tundra log manifolds with a 3" Y pipe that mates up to a 3" exhaust with resonator and import straight through muffler......Its loud enough when I open her up, but when cruising shes got a great sound. Ill try to upload a video this upcoming weekend.

Glad to see people are still doing the swap.

Who all has a VVTi UZ in theres?

I have a vvti up and running. I'm just doing some suspension work before it's back to daily duties.

[aarongdl]

Do you have any pictures of it?

I would love to see it!

I'm still awaiting my harness back from Rob so I can get mine running.

Still wanting to do a few more things, but I haven't even ehard the sucker start up.

It's a lil messy but it gets the job done.

What are you guys with vvti doing for ecu/harness, and manifolds? I heard there were some immobilized issues with vvti

The ecu I ordered from Russia.( super fast shipping) with the immobilizer bypassed and couple of other bits bypassed with a module for a/c. PM Mr. Chow and he can get you set up with the fb group. Truly great thread for all years of 1uz-3uz.

The harness I made from a stock 99 Ls400. Everything functions as it should including the obd2 port.

The passenger side manifold clears fine. The issue is still the driver side. I used the stock driver side and modded it to fit around the steering shaft. (I taught myself with the help of reading and youtube how to weld just to do this project so excuse my inexperience welds)

Those headers look pretty good, actually.

I'm currently running some custom ones (i've spent a good bit of time in the facebook group)

I'm awaiting now some new mounts so maybe I can get the motor running and driving at some point in my life.

I'm not sure how I feel about all of Collins' equipment though. Not to bash the guy, but everything of his I see complaints about it all being really inconsistent.

Mailman, have you have a chance to have the VVTi car dyno'd?

I would like to dyno mine once it's running and driving of course.

98 1uz VVTi with a KA trans an J30 diff

[mailman31090]

Thanks I appreciate it. I'd like to go back and make some custom ones but for now these are fine.

For whatever it's worth, I'm running second hand Collins mounts and they've been pretty spot on. I was pretty hesitant buying anything from him after reading through the thread and seeing the complaints but I needed the adapter plate and the tob sleeve so I ordered those from him directly. The service was good and he had things quickly shipped out. The sleeve was a cnc'd one piece unlike the old welded together one I seen early in the thread.

I had one issue with clutch disengagement but it wasn't due to the Collins piece it was because the fingers on my pressure plate was bent (old clutch setup I had laying around and trying to be frugal lol). Bought a new exedy one and everything was working like it should.

Unfortunely, I haven't had it on the dyno yet so I don't have any numbers.

[aarongdl]

I understand, if you don't mind my asking, how did you transmission mont line up?

I've almost contemplated a custom one as lining up the auto trans mount hasn't worked out well for me I don't believe.

[mailman31090]

I'm running a ka trans too for the time being but with a manual mount. The front two holes on the bracket line up with the two rear holes on the body.

I can do immobilizer service for vvti 1uz. send me a message and we can arrange it all. I have experience with the 1mz vvti and essentially perform the same programming. No weird a/c module though.

I've seen two different methods so far of the immob bypass for the VVTi

One is like the Russia where the bypass is flashed to the ecu and another is with a key fob being paired to the ecu and wired up inside the ecu.

Which is yours?

dont mean to butt in, but i have the russian guy one (cool guy named yury) its built into the ECU and he has with device that simulates something that keeps the ecu from running into limp mode so you can get the full power of the vvti otherwise you will be running 200hp instead of the 290hp

im routing all my wiring now, a PITA because im a idiot on wiring. im building a fuse panel too. this is going to suck.

since theres no write up on this i might do a simple one to help others but i need to make sure my wiring is right first.

sir thank you for sharing your work.

i have questions but im only going to ask my biggest question

1. what did you do for your fuel return line solution?

ive only heard 2 options:
1- consist of drilling out the fuel rail etc and adding a fpr
2- was getting a fuel filter that has a internal fpr and return.

Yea, Yury is the man. He's the one that did my ecu, real cool guy.

1UZVillain, as far as fuel return you don't have to drill out the rail to add a fpr. Since the 1uz vvti only has a single feed with no return at the rail I placed the fpr before the single feed to the rail pulsation dampeners. I used an ebay aeromotive copy and replaced all the internals with genuine aeromotive parts (regulator, spring, seat, bolts, etc). It's a 3 port so 1 feed from tank, 1 return to tank, 1 feed to rail.

You can also use a 3 port internal fpr fuel filter like you stated from a vw or audi. I believe those are set to about 58psi (atleast the ones I found). Other car makers do have them to so you can find one for what pressure you want to run.
