Ok, what you need to do is get the bellhousing and flywheel from a 2.5-liter 1JZ engine (found in the JZA70 Supra) and then run a 7M-GTE clutch. Search Google for
2ZJ R154 and you should find a LOT of resources on how to do this. 1JZ = 2JZ bellhousing bolt pattern, and the 1JZ came with the R154 transmission. Do some more searches for
1JZ transmission R154, etcetera
We have been building our
RACE R154 Transmissions for MANY 2JZ Supra and Lexus owners, replacing the 6 speed box with the 5 speed R154 box.
