I have a few questions, most of which I have tried searching for but have come up empty handed.

1) Name of 1JZ Trans
2) What the 1JZ motor can take when referring to boost (psi)
3) What a stock sc300 (92') rear end can handle (tq/hp)

 

Haha, good thread.

I hate when people say search as I think there should be at least someone to point you in the right direction.

The Forced Induction/Engine Thread right above ^^^^ has like 10 topics on the 1JZ on the first page.

1. R154=manual
2. Boost(psi) is always different depending what turbo(s) are installed. If you are talking about a stock 1jz, which I am assuming you are, people say 16ish because of the ceramic turbos.
3. I dont think that many people are running into differential problems regarding reliability powerwise, it is more of the question of traction.

 

I've moved every thread you've posted so far, please use the engine forum

PLEEEEASE

 

Sorry about that. I'm a long time member of H-T and have just become to accustomed to their layout. When I searched "1JZ" "1JZGTE" "Differential" "Transmission" "Tranny" and so on, nothing came up. Thanks for the answeres to my simplistic questions.

When I was referring to boost #'s, it would be on a 1jz with gt35r. Just curious what boost levels seem to make em' POP.

 

The 1J blocks are just as strong as the 2J as far as I know. Check on www.supraforums.com they have a lot more 1jz info.

 

i thoguht the w58 was the 1j man tranny??? i could be wrong though.....psi wise, stock turbos or single?? be more specific....
stock turbos- about 14
single w/440-550 inj-18-19

and copy what cherplex said, hes right

 

The R154 is the 1J manual tranny. I wish Toyota would have put that R154 in the NA 5speed SC's and MKIV's..

 

thanks for the clearing that up.....i want to go 5 speed while im gone.....think its a good choice??
