Thomas,
 Much easier to use 13B 87-88 turbo rotors (8.5-1 comp ratio) or 89-up
turbo rotors (9.0-1 comp ratio)........I have never heard of anyone
doing what you  suggested........FWIW .........Unless you are talking
about using a 12A engine........The turbo 12A was never sold in USA
but some J-spec 12A turbo engines are being sold here by importers.

Kelly,
 
great pic! This also shows that there seems to be very little space to make the dish in the rotor deeper for a lower compression ratio.
Do you know how much one could mill out of the rotor before it gets critical? Obviously the idea would be to modify the NA-rotors for turbo use.

Jesse,

  Rotors are cooled by oil spray from jets in the eccentric shaft .
