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.
Be sitting down :)

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 Lamar


Dave, the exhaust manifold in the photo looks like the one I have for my
rx8 engine. Any chance you or someone can post a pic of a manifold used
for the rx8 irons and gsle rotor housing combined?

Thanks!

Paul -- not sure where you might want to post these --

Picture names tell what they are ---

Fabricator is www.JSPFab.com

Inconel heat shields were priced extremely fair as far as I was concerned.
Paying myself minimal wages, I would have spent much longer than they
charged, to make something that was not as nice, and would not work as
well.
AND, sliced the crap out of my myself on the sheet inconel even with
gloves.

Paul -- The Haltech P-1000 we are using DOES have an input channel for a
knock sensor. I am looking into adding one.

Woa!
Thats great!
Thanks a million Dave.
The welding's a work of art.

The whole thing would fit under my cowl if it were'nt for the intake
sticking up so far. I have more space on the sides, so it won't need to be
so tight.
