fd3s torsen into s4turbo?
 

hi guys!

I'm a little bit confused

will a stock fd3s torsen fit into a fc3s s4 turbo build 1987?

because on ebay the seller says that the fd3s torsen will only fit into 89-91 fc's

thanks in advance

Yes it will fit, the FD rear end was 8", So since the TII is also 8" it will fit. Now also there is a great write up that was just posted with in the last few days on how to install it here TORSEN LSD install write up

yeah, it's actually easier to put in an 87-88 turbo because you can use your stock stub shafts.

i've already fitted a miata 1.8l NA torsen into my s4 NA winterbitch :) but thanks for th writeup!

one last question: does the torsen from the fd3s works like a 2 way or like a 1 way lsd?
thx guys

It's more like a 1 way. No lock up on deceleration.

thanks guys!
