Default Which tranny for 1UZ?

Hy!

i read many threads in some car forums it gives 3 possible transmissions for more or less easy install on a 1UZ in the SC400.

W58 - smooth shifting, easy to install, but power handling not g reat?
R154 - shifting is not smooth, handle power up to 1000hp? Install little bit difficult.
V160/V161 - too expensive

i can buy 2 W58, one is a japanese "facelift" version with stronger internals. gives this W58 really? both 120-130tkm used.

how much power is possible to kill not the W58? i will do maybe NA tuning and/or a M90 Blower. This too much Nm for the W58? i will not only cruising, i will sometimes without any fear do a burn out, go sometimes maybe on track and donuts (no, i will not kill my car, but i will have no problems with high torque and killed tranny later)i read many broken W58 trannys, and also up to 500hp no problem

Many members drives a W58 here, i would be delighted to see, any experience with the different trannys on a 1UZ (stock or boosted)

thanks!

Tom

I'm going with the R154. I'm planning a M90 or similar setup down the road, and from everything I've read, if you plan on boosting, the R154 is the way to go, as the W58 can't really handle the power.

Thanks for the good answers!

my first idea was a W58, but i think the R154 is better

Gives different types of the R154 transmission? i know only the R154 in the supra turbo MK.III, have the NA Mk.III have he W58? The Soarer 1JZ , i think have the R154?

Its better to use a adapterplate to the AT housing maybe from quantum



or a complete R154->1UZ housing?

thanks!

Tom

Hy!

i wrote with quantum, the steel FW have 21 pounds, the LFW only 11 punds

the Tilton slave cylinder costs with the kit 280 dollar.

a good offer

im correct, i can drive with the SC AT driveshaft, but the is a little bit too short? this is no problem, i have a very good shop in my near, a specialist for driveshafts

greets

Tom
