Torsen for NA FC's

Anyone have an idea if this fits directly FC NA open diff without any modifications, with stock output shafts?

thanks!

As far as I know you dont need to change your drive shaft to make your NA LSD into a Torsen.

You mean the axles stubs that poke into the diff itself? Use S4 N/A ones, I used ones from an open diff in that writeup and they were fine. The diff I was using was a S5 GTUs diff that already had a viscous LSD, and its axle stubs were unequal length and didnt work. I cant comment on whether or not the S5 N/A open diff stubs are the same, as Ive never had a set in my hands.

Does anybody have experience with those lsd's off of ebay? I don't really see the brand of it, but the T2 torsen one in the link.

Why doesn't he put that in the ad? Or am I missing something?
It just seem too cheap to be a mazda brand and new even...

Is that the same as this one? This is a T1 the other is a T2. what's the difference?
