to turbo an NA rotary motor is asking for trouble. you dont wanna run more then 6psi.
the rotors have high compression then turbo rotors and once you detanate once, its rebuild time.

for serious power look into a 13brew. for an easy direct swap... get a TII motor and tranny and diff. they are ALL stronger.

we almost have our 13bt running in our rx3 with a NA tranny. we'll see how well it holds up
