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!

"Mazda Miata Torsen Helical Gear LSD !
For the '94 & up roadsters.

This is the 'T2' style Torsen"

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

its meant to fit 94+ miatas so it will fit inside our diff housings and fit our axle stubbys

I did a write-up a few years ago with pics:

https://www.rx7club.com/2nd-gen-archive-72/how-swapping-miata-torsen-lsd-into-n-fc-diff-housing-229115/

yeah, but what lenght are open diff output shafts on NA's? both same and good to go with Miata 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.

Brand is MAZDA and it works, same way like FD torsens in Turbo II's

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?

i suppose its not new, its just pulled out of some miata in Japan....stock unit

He just emailed me back and the T1 are SCCA legal and the T2 are not. Still not sure which one or if both styles fit in an rx7 non turbo S5
