I don't know if I would call a magazine article "official." They only real way to know would be to talk to some people at Toyota who have that information available...

The publication has been spot on with most of the specs I have check for other items. I think of these two hyper rev publications the closest thing to a Celica bible that could exist.

I am trying a custom gear stack up in my trans and have been looking for the part numbers for third and fourth gear from a ST185 Rally and can't seem to find them. I need #3 input and out put gears and sincros, and #4 input and out put gears and sincros. If any one could point me in the right direction that would help me out alot.

St185 Rally (1989.9/6):
Final Drive: 4.285
1st (3.230); 2nd (2.142); 3rd (1.518); 4th (1.258) 5th (0.731)

Search for the thread I made about finding the secret lost gear ratio document. It may help you.

Close ratio perfect for many of you.
Gerbox E56 form Celica ST202 - 1993 . Popular in UK. With LSD Viscous.
ST202 Celica SSS 3.583 2.045 1.333 1.028 0.820 Final - 4.238
If for sombody this gearbox is too long - you can put final ratio from RAV4 4,562 or 4,933.
I put in final ratio 4,933. Work perfect.

If sombody need i have final ratio too gearbox typ E 4,238 72/17 for seel.

But can this fwd gearbox be adapted to the gtfour transfer case?
