Diff swapability question..........
Is it possible to use the SC300 4.27 diff with the Supra Torsen LSD on my 95 SC400? Already have the Supra Torsen installed into my stock unit. It had 10 bolts I think.
Any thoughts on what the change might be on the dragstrip and for daily driving?
Thanks,
KC

To answer part of my own question I dug up Blizzy's old thread (whatever happened to him anyway?)?
The Torsen can be put into the 4.27 diff I'm just not 100% sure that the 300 diff bolts to the 400 driveshaft. Not sure if he changed anything on the diff end of the driveshaft since he did a 5-speed swap as well.

If I'm thinking about it right, the 4.27 gear in place of the stock 3.92 would get me the 11's 1/4 mile I want so much. Right now, I trap at 115 or so at about 6000rpm. The 4.27 would put me at about redline when going through the traps and in theory, get me there a little faster.

I didn't make it out to Mooresville. Went to Rockingham on Sunday, didn't run too great.

And, if I'm not happy with it, I'll just swap it back and be out the cost of the diff.

Factory 5-speed = 4.08
Factory auto = 4.27
-----------------------
I have a SC300 auto diff on the way. Since the 300 and 400 auto trannies are basically the same and have the same gearing, an SC400 with a 4.27 diff will have the same overall gear ratios as an auto SC300 does from the factory.
I wonder if using an SC300 speed sensor will make the speedo read correctly?
