THANKS, BUT THATS NOT THE ANSWER IM LOOKING FOR,.

 

no help?

 

No you don't need a diff from a turbo mkiii. I mean you can, but it's not necessary. Are you worried about fitment issues with the driveshaft length or something. All the Supra's 8in differentials are interchangable.

Look on the door jam sticker for the date. For an 89 model it should have been built in late-88 or early-89. What does your tach go up to?

 

the door jam has "aug 88".

the reason i ask about the diff is because a few people told me that i would need a "turbo diff" for my n/a cause i was going 1j.

thanks

 

na man u can rock the diff u have on ur car now...driveshaft will bolt up to it no matter what...if u want a turbo lsd diff holla at me i can get u one

 

iight, good looks....what about the pre89 question?

 

Lets finish this thread already! No your Diff is fine! I would swap a turbo transmission the (R154), into the car if it was me. The (W58) which is what you have currently is crap and will not hold that much power. Yes you need a rear sump... That should be pretty obvious! The only thing you need to change is your bell housing to get the Tranny, Drive Line, and Diff to hook up properly. Yes look at your door jam it will answer the question you are asking...
