I believe it compares to an ACT Stage 2. So I'd say somewhere around 300 tq.
I traded my WELDED diff for a Z32 diff today. Install was very painful, and annoying. But it is much more enjoyable.
No more skipping, no more destroying tires while daily driving, no more hassles, no more pissed-off-ness, no more trouble. welded diff, be gone.
(not my pic, but looks like this)
Oh, and my ARP head studs, and gaskets came today as well!
Pulling my motor out on sunday, putting the new one in on monday.

huge success
