3rd gen diff in a 2nd gen?
well I'm sure there have been some post on this but I'm tried as hell if anyone can tell me what is required to do this swap I can get a 3rd gen torsen diff for 200 with only 12k miles on it!

ummm no. enless something has changed, torsens still spin the inside tire for a bit, then grab. have you ever seen a 96 impall with a torsen run auto x? i have, the inside tire lights up like crazy for 1-3 seconds then grabs, breaks both tires loose and spinns the car around.ive heard that torsens also create a lot of heat from the worm gears, so they arnt all that good for autox or road racing....

You're stating what you've seen and not experienced. That Torsen in the Impala might have been worn out, they do wear out and they aren't as rebuildable as a clutch type LSD.
BlackRX7, call Mazdatrix and ask them if it can be done, they might have experience with this.

Yes aight dude if you don't believe us check this, it's direct from the mazdatrix site
In comparison with viscous type, or friction type LSD, it has the following benefits:
1) Large bias ratio torque proportioning
2) Less change of bias ratio over time of car use
3) No special differential oil or LSD additives needed
4) Improved overall traction and improved controllability under acceleration.
5) Virtually no change of torque sensing or traction control through differential temperature range
I know someone knows, Ted or Hailers?

when u turn on speed vision and u see those production class touring cars running around, im pretty sure they are using clutch type LSD's that are fully adjustable. they can change the amount of clutchs in the diff for track conditions and alter the amonut of locking for on and off the throttle. They have been doing this for some time now (over 40 years), and im sure they still are.

but the fact of the matter is Mazdatrix even say there better.....if you wanna argue with them, tell me who wins.....
and remeber this is with the rotary, which doesn't have as much torque as hp....the impala's have a restrictive ecu which only holds them to around 200hp, and like 280 to 300 torque, hell yeah they'll spin around a 90 degree turn!

The problem with the torsen unit is it has nothing to absorb shock, as the clutches do in the clutch type LSDs.
Thats why they break with a lot of power, Ask the Fds guys they uprgrade their diffs to T2 diffs. So are you gonna use this car for autox or drag?

The diffs are actually identical in size and shape between the FD and FC.. I have a FC cusco diff in my FD. I would recommend getting new bearings for the diff while your at it since you will be putting the diff in a diffrent case.. Basically all you have to do is swap out the ring gear and put it in...

The overall diff, including pinion carrier and housing and so on are very different - the FD one looks kinda like a squashed shoebox.
BUT, the LSD hemishpere is interchangable between the two.

you can use the FD diff in the FC pumpkin...
one note though... the torsen diff can not handle as much power... too much power and a wheel hop = gears turning into nice metal peices...
an s4t2 diff is probably the best, it can grab the quickest, take lots of abuse... but u have to rebuild them, since hte clutch plates wear out
