 perhaps it
would be cheaper to design from scratch a smaller, all aluminum P-Port version
of the Mazda 13B specifically for ultra lights with detonation gun coated
rotor housings to avoid the high tech steel liner. I have a few ideas
for improving the water flow in the block as well. In the quantities we
would sell initially sand cast housings maybe be cheaper than die cast
housings anyway.

 Now you're cookin' with gas!
For us interested in the very light stuff bhp is not the issue. Apart from
reliability the issues are :
1) installed mass
2) bsfc
3) installed mass
4) dollar cost
5) installed mass
6) power to wieght emphasis on WIEGHT
  You have my undivided attention }:-))

The Wankel GmbH as it is now as I recall is charged cooled. That is a drawback
for breathing at high RPM limiting the HP. Therefor the dies would
be of limited use if we copied the Mazda, scaled it down and made it a P-port.
