This engine runs 60 inches of Hg manifold pressure.
  To my knowledge this is the first 6 port exhaust
  engine. It uses both the 3rd gen RX7 rotor housing
  and the RX8 end housings for an unprecedented
  exhaust port area size. It is probably using
  low compression rotors from the 3rd gen.

  The turbo is covered with
  embossed  thin sheet metal Inconel as a heat shield.
  Contact Mazdatrix for a price and availability.

 Engine uses 84-85 GSLSE 13B rotor housings and the stock 10:1 RX8 rotors.

 Inconel heat shielding is custom made by www.ATPWrap.com

 Do you have a knock sensor on it Dave?

 BTW who makes that 2nd gen 1991 Turbo II SS exhaust manifold?

Paul and anyone else that wants to render a guess-

What would be the life expectancy of this engine in an aircraft? I really
like the idea of using 3/4 throttle to take off and having lots of reserve
without an extreme weight penalty. I assume that if the pilot were inclined
to he could throttle back, cut back on the boost and save gas, or he could
burn it up too.

Just a thought, but any guesses on its expected life in normal A/C service?

I don't know what the life expectancy is of this engine in aircraft service.
My guess is the turbo would not live for more than a few seconds at
a time.

For this power level you would be better off with a 3 rotor turbo.
Here are some pictures of Tom Parkes 3 rotor turbo powered
Lancair ES. This airplane is near identical to a Cessna Columbia
except for the engine of course. The turbo used is an aircraft
turbo and not an automotive unit.

Tom lives in Kingman AZ if you would like to see it.

There are better places to put the water rad so please don't
copy this configuration. However as far as I know it is cooling fine.

I'll do a 3D turbo layout for a 3 rotor like this that will fit in your
cowl if you send me some dimensions.
