OBX Diffy.
#6
All NA RX7 diffs are the same 79-91.... Actually, I think pretty much all 7" mazda diffs are compatible ie: use the same spline count, ring gear pattern, etc. these are found in the RX2, 3, Miata, early RWD 626, etc.
I too have been looking at the OBX as the Miata Torsens are hard to find. There are a couple guys who have been running an 8" OBX in their FD V8 swapped cars for a few years without a problem. That's a pretty good record. Here is a stock FD torsen after the V8 treatment...

There is also a vid of the guy with the OBX a few pages in thrashing the car...
Has anyone out there actually tried an OBX diff and had it fail? All I see when I search is hearsay and rumors...
