I intended to use the toyota tranny when i was doing the 1jz conversion. it was the little pieces needed for the conversion that put me off.
I will be staying auto for a while but my heart still leaning towards manual. i guess there will be a manual conversion in the future.

can I get my stock diff modified to the ratio I want? also can it be modded to LSD (apart from welding it)?

also my front lower arms bushes seem to be failing and failing again. could it be the extra weight from the heavy metal 1jz thats causing it?
any solution to solve that?
