G'day lads.

Car is a jap spec 92 soarer twin turbo (1JZ-GTE) with cat back exhaust, 13psi, pod filter and standard auto transmission and diff

the diff in the jap spec auto's is pretty shoddy, looking at getting a nice upgrade, hopefully something with better ratio's for dragging.

what do you guys use?

JZA80 twin turbo RZ supra diff is the first which pops into mind..

thanks in advance guys

You're already geared pretty high (numerically), the sticks are actually geared lower (numerically), but since we didn't get the RZ Supras, not sure if they fitted a different R&P than 3.13 and 3.27 in the Getrag models, you may want to check it out...

 

The RZ supra 6speed is a 3.27 auto is the same as the america model which is a3.73 if memory serves me correctly.

 

Ok

I think i will swap to the Supra twin turbo automatic LSD and use a JZA70 supra 5 speed gearbox behind that.

Thanks guys
