Paul (and anyone else with an opinion),

   I need a 200 HP rotary engine to put in a Glasstar Sportman 2+2.  What is the best choice?
    1.  The old 13b rotary from the RX7 days?  (2nd generation, 1989 or newer)
         (Will parts be hard to come by in the future for this engine?)
    2.  A Renesis 4 port engine set up for an automatic trans?
    3.  A Renesis 6 port engine (which I believe was set up for the manual
         trans only, I may be wrong)?
    4.  Or should I be looking at something else (of course still a rotary)?

As a second point, is anyone working on or looking at an intake manifold
and an exhaust manifold for the 4 and 6 port Renesis engine.
    Thanks.                    Dennis

You have come to the right place.
If you look at a stock 4 or 6 port RX8 manifold you are seeing part of one.

Yes the six port is for the manual transmission only so you will need
an auto transmission counter weight and an auto transmission
flex plate.

It will be easier for you to get 200 HP out of a six port RX8 engine.

It is rapidly getting to the point where RX8 engines are easier
to get than earlier engines. Mainly because the racers are not
too fond of them. Side ports don't breath as well as peripheral
ports. Mazdatrix just got a brand new RX8 engine in trade for
a third gen dual turbo engine going into a brand new RX8 car.
Mainly because 400 to 500 HP was available for the third gen engine
and it is nearly impossible to turbo an RX8 engine (due to the
unavailability of low compression RX8 rotors) and get 400 HP.

Thanks to the racers the parts will still be available for the older
engines into the foreseeable future.
