Here is the response I got from = Mazdatrix about=20 using RX-8 rotors in a 91 block.  The rotors are $270 less than the = 9.7:1=20 rotors, but I imagine that milling the slot deeper will cut into that = price=20 differential a bit.  But, on the other hand I could have an RX - 7 = 1/2=20 engine in my aircraft.
I am going to look into this a bit more = and find=20 out how much to mill a rotor.  A lighter rotor =3D> more rpms = without=20 increasing stress?

You can run the renesis rotors if you = get the apex=20 seal grooves milled deeper to accept the 86-95 apex seals, or the 74-85 = 3mm=20 seals. The Renesis seals are not tall enough to pass over the exhaust = port=20 without warping and breaking. You also=20 need to run the 86-95 corner seals, not the Renesis corner seals. = (there's a=20 metallurgical conflict with the side housings) 
The front and rear counterweights from = the Renesis=20 engine to balance the rotors are available.

Can the RX-8 rotors be installed in = the 91 13B=20 block?  Assuming you get the seals,bearings, etc for the RX-8 = Rotors?=20
Are counter weights for the lighter = RX-8 Rotors=20 available?
