Found this info.
I am not positive about the 90-94 LS400 but I believe it is a 3.62.
The 95-97 LS400 has a 3.62 gear ratio.
98+ LS400s have a 3.26 ratio.
No LS400 was offered with a LSD.
Attached is a picture of a stock LS400 differential.
The following info is mostly from an early Supra factory repair manual:
The Supra TT 6speed was offered with a 3.13 initially but was changed to a 3.26 and used a 220mm (8.66") ring diameter. It also used 4 point rubber mount attachment whereas the automatics and non-turbos used 3 point attachment.
The Supra TT automatics had a 3.77 ratio and used a 200mm (7.87") ring diameter.
Both Supra TT diffs were initially torsen type.
The non turbo Supras were 4.27 ratio and used a 200mm (7.87") ring diameter. Clutch type LSD was optional.
