6 speed torsen in sc400?
hi
want someone confirme that:
may I use 6 speed torsen mechanism (only torsen not all pumpkin) and bolt it to my stock sc400 ring and pinion?
that way I can have same ratio 3,92 (stock v8) and have torsen diff. I heard that 6 speed have bigger ring that is bolt to torsen case on12 not 10 bolts and it will not work with my pumpkin case. Only supra tt automatic will work cause have smaller ring and it is 10 bolt??
same question about all pumpkin from supra 6 speed. Heard that it will need change left axle too cause 6 speed diff is biger on left side and stock axle will be too long...
se that:

I second that opinion(?)
Besides the 10-12 bolt and size difference in the ring gear, there is also a size difference in the carrier bearings. The 6-spd LSD internals are just not compatible with anything from the SC or the TT Auto.

if I decided for supra tt 6 speed rearend must change left axle too.
what about drive shaft , can I use stock sc400 driveshaft and will it be bolt on to supra tt 6 speed rear end? or not?
thanks

You would be going from 3.9:1 ratio to 3.2:1 ratio. That is a big difference.
