Yep........

alright i was looking at getting a half cut from a tt instead of getting everything separatly. just figured it would save me time and money. the only problem is almost all of the half cuts i can find are from jdm supras so they are right hand drive. could i still use the ecu and wiring harness in my american supra?

Unfortunately, the harness would not fit. The ecu is possibly workable, but you may have to change some sensors...

lsd
 

hay i have a 94 na supra n i wanna get n lsd the trd lsds mostly say 6 speed i wanna know if theres a diffrence between them if i can still use one
if anyone knows anything would help thanks

I'm certain the n/a diff is completely different (eg. gearing, LSD capabilities, etc.).

To answer your question: I am not 100% sure, but my best guess is that a 6spd TRD LSD would not fit into an n/a diff.

Why not get an entire oem Mkiv Supra Turbo 6spd diff and swap it out?
