I haven't heard of anyone using the diff in the miata, but I know a bunch of people using the diff in their turbo Honda's. They work really well, but apparently the rule of thumb is to replace all of the bolts in the unit. It's something like the Greddy turbo kit, the bolts they included are crap and break.

This might be a VERY relevant question to those who are pondering a budget V8 swap and dont want to custom fab a new rear setup too.
That article is great. It looks like the OBX is a different design overall than the Quaiffe. So maybe it is a knock-off of something else, or maybe it is its own design, which would be pretty cool IMHO. Replacing some washers and bolts is not a big deal.

I've put the OBX in my 1.8 4.1 rear end. I also installed the hardware kit Jeff mentioned earlier. I'm running a turbo 1.6 with a 6 speed. So far, I'm happy with it. It handles 180-200 HP and works perfectly. I autox the car and don't baby it on the street.

This link shows how to rebuild the OBX and at the bottom it appears the guy sells the upgraded bolts and belleville washers for $32.
