OK, Nitty-gritty time.
Both the MKIII and sc300 Toyota Differentials are technically eight inch diffs (Ring gear diameter). Toyota 8 inch diffs also have 30 spline axles.
They are both technically "G" code diffs, which have been used from 70's-mid 90's.
This is where the major similarity ends.
There are too many google jockies, so I am going to once again prove the net' zombies wrong (No one said a GTR32 drivetrain would fit into a 240sx, I did with hand tools. Look up "GTRs13")
The MKIII Pumpkin can be fitted to the sc300 but not without modifications.
MKIII on right (Wider), SC300 on left (Narrow 8" "G")
Cover flanges are almost identical minus the width difference.
MKIII Cups won't bolt up to sc300 flanges, but because it's a 30 spline axle both cars have...
...SC300 AXLES FIT MKIII CARRIERS!!! (Not perfectly, but the splines match)
All that has to be done is mounting, and driveshaft flange which also swaps over!
Take that, nay-saying lemmings! HAHA!!!

I'd love to see this work but the SC/GS/MKIV diffs are very strong with or without an LSD installed. Adding a TRD 2-way or Kaaz 2-way is what most Supra owners above 500hp do anyway which requires money and work on par with fixing an SC's open diff. Using an MK3 clutch-type LSD isn't the best project option either unless you'd be willing to get a better aftermarket LSD installed anyway. TRD LSD's for those MK3 diffs are far superior to the factory units except for the last couple of years of production (91-92 were Torsen IIRC). MK3 diffs are a better swap into IS250/IS350's and IS300's. I'm not certain but the FR-S may also use that style casing as well.
With the fabrication and means of doing this it would be very cool to see it work. It'll just be a LOT of work. I'd never attempt it but I'd love to see someone figure it out. I just think it might require a subframe swap or custom subframe with re-engineered suspension geometry.

The SC300 axles fit in the MKIII Carrier, the driveshaft flange swaps over, and all one has to do is mount the actual pumpkin where the front ear mounting solution is the most difficult.
Buying a KAZZ for the Narrow G diff is a waste of money if this can be implemented with little effort.
