CAS = Crank Angle Sensor.
REW = third gen engine.
Renni = RX8 engine.


Paul,

I believe you are correct on the interchangeability of
13B and 20B parts of course. Intermediate housing and e-shaft that are
unique. If I had a lot of money I would be interested in building a 3 or
4 rotor using the Aussie e-shaft and bearings, (or was that Hurley)
anyway I liked the standard Cosmo housings between 3 of the sections. PP
irons would work great too. That would be a truly power packed setup. Do
you know if anybody has one running yet?

Lots of p-port 3 rotors in road and drag racing. It is the only thing
competitive when running against larger 3.6 L to 5 L BMW's and Chevy V8's.

P-port turbo 3 rotors are yielding 1200 HP for boats and drag
racers. Check out the web site as we have up dated it a lot with
new videos and a bunch of other stuff.
