I believe that what he is asking is for the whole rear end. He is running a piston engine swap (rb25det) and is probably looking for a stronger rear (that is 52" disc-to-disc). Also, he is in Aussieland, so rears that might be available to us, may not be to him.

I doubt you have them but the Ford 8.8 in the V8 explorer is just 20 mm wider than the FB, not sure if that is the GSL or GSL-SE which has wider axes.

If you can't it's not hard to have ne built to your specs. I used to have a great guy in Dandenong, Victoria who built several 9" for me, but they are too heavy,stick to an 8.8.

That said why change the Mazda rear end, they can withstand very high horsepower levels, LSD are easily obtained here in the US I know they are harder to come by back home

Though I believe cold heartedly that all RX series cars should be used with rotary engines only, not everyone shares this opinion.

This is this person's personal goal with the car and its not exactly nice to be putting him down for it, you can offer solutions and convincing evidence, but lets try to keep this from a bar room brawl over stupid things.

Secondly, he may be looking for low end grunt, after all our rotaries aren't exactly famous for their high low end torque.

Anyways, if you live in Aussy Land then I would say try and match up some of the european cars and see if you can snag a diff from them, but I would say a 9" or 8.8 is your best bet.
