Sucks to hear Sav. I assume the plan is to avoid the dragstrip in the future?
Our diff's suck *****, even the 7's. We (anyone) need to start upgrading to the RX7 Turbo II's (8") if we (anyone) wants real drag racing.
I hope to do a few passes later this year, but will ease it off the line as a 3.636 isn't cheap, nor is a good RX7 clutch pack diff.

I was hoping it was an open and that my failure last year was just a fluke, but now you have me worrying..
If you want another Torsen, I know Blake @ www.isellmiataparts.com just picked up a '94 with a Torsen.

Nah, it was a really crappy launch, like a 2.12 60".
I was hoping it was just the R&P, and I could throw a new one in with my Torsen and case and be done.
Ohhhhh, no.
What one of the 4 parts of the Torsen are supposed to look like:
What 1 of mine looks like:
What the other two look like:
R&P is chipped, Torsen is totally trashed, and the case is cracked. Total writeoff.

ok so the moral of the story: torsens suck for clutch dumps. the end.
It looks like you chewed an internal torsen gear, the diff froze, and then ripped the meatball right out of the bearing retainers. ouchie.

Yeap, same thing that happened to ApexOnYou, torsen died and took the rest with it. That sucks. Well, I'm definately scratching torsen off my list. Welded diff for me. What are you going to do Sav? I think a welded open diff would be cheap and super strong if it's welded up right. And I hate your for having a 2.1 60' time.

Our 7" differential isn't the weak link IMO. Well, it sort of is. Wheel hop is what kills ****. Our diff winds up like a spring when you launch it. The front of the diff jumps up and nothing stops it. Look at how the RX7 diff is mounted. Ours needs to be supported just like that, with a brace between the frame rails holding the front of the diff. Stop wheel hop and the diff's would stop breaking.

A 2.1 60' on street tires is not bad at all.
Looks like the exact same gears went on both of ours. One of those side gears went on mine, and two or three others split clean in half when the whole unit locked up. I wonder if cryo treating would help any?
And for the record, I wheel hopped for the first time the run before I broke mine too, so maybe that has something to do with it.

This car is primarily a track/autocross car, but I want the ability to go to the strip, put on the R-comps, and click off some 2.0 60 foot times. Welded diffs aren't an option. I am looking into a hybrid Rx7 option, and I need to do more research into (read: someone needs to tell me about) an 8" Rx7 TII diff.
edit: the 2.1 was on NT-01s. Not drag radials, but not street tires.
