Paul,
        I will need the intake.  I would like to talk to Mike Mcgee

about 6 to 4

port conversion. Do you have his Email address? Another possibility is to
buy the optimum housings when I start building up the engine.  I would like
to use the 89 Eshaft and rotors probably new rotor housings but do you go
turbo for big ports or NA for exhaust silencing?  Turbo II end and
intermediate housings to get 4 port config?  Or do what Mike did?  Thanks

You got me confused Joe. Try re-wording it :)
As far as what Mike did (hogged out six port) we don't have a lot of
feedback yet.

I bought the engine this way from a quarter mile racer.  It was installed
in an early RX-7.  The porting work had been done by Rob Golden at
Pineapple Racing in Portland Oregon

The only thing I know is what he told me about the performance, I'm going
to report back when it is running on a test stand with a prop.  I have a
number of props available to play with so I'll be able to calculate HP
curves using torque measurements.

According to "legend" it will make 220hp at 8500 rpm.  The previous owner
said it had seen the high side of 10 several times.  That was with a after
market points type distributor, Racing Beat four barrel manifold and a
small Holley double pumper.  8500 is my "War-Emergency-Power" red line with
a 2.85 redrive (2900 prop).  I expect to cruise at approx 6000 rpm (2100
prop) and will try to dial a prop in for that.  Until it flies this is all
speculation.  It should out do the 150 hp Lycoming that's in the plane now.
