So please correct me if im wrong, but the supra TTR's came with bilstein suspension, momo steering wheels, and recaro interior. My front clip came with all those and the TTR's are supposed to come with a Torsen differential. How can i tell 100% if i have the torsen diff? Any help would be great

The one in the pic on the left is definitely a T1 Torsen.

The carrier (the outer casing) is definitely NOT from any A70 Supra though. The carriers, out of any A70 Supra, with the exception of the euro spec ones with MORE fins, all look like just like the one on the right.

It looks like a MKIV Supra or Lexus carrier. Does it have fins on the bottom? If it's a MKIV carrier, it's worth some $$$ over the MKIII carrier. Also, what is the ratio?

Looking at that subframe again it does look like it could be a MKIV subframe. I know you were thinking it was and wanting it to be a JZA70 subframe, but I'm sure the MKIV (JZA80) one is worth more, so it's probably more good news than bad.

Looks like the JDM one is different than the USDM one for the MKIV's.

Thanks guys, i was thinking about installing it in my car so that might be bad news hah. So your saying the pumpkin looks like its for a jza80? I bought a jza70 front clip and this rear end came with it. I saw another front clip for sale but the rear subframe arms were longer and it looked differant so you may be right. Is there any way to tell for sure?

Looks like a JZX90 housing (japanese cressida)
Same 8" Torsen as the A70, different output shaft flanges.
Note the bolt pattern difference.
Housing won't fit the A70, neither will your halfshafts fit those flanges.
The only way to use that is to put it into a Supra housing (with the work & expense of reshimming both the pinion, and the carrier bearings),
and find halfshafts out of Japan with that small bolt pattern.
