O.K. Thanks for the information. I'm new to the rotary engine concept, but
is a peripheral port basically a long intake tube that goes over the top of
the engine?

 The lightweight end housings sound like a possibility.
A lot of Mk IVs are flying w/ the Subaru EA81 conversions which can make
around100hp at about 200lbs (kind of heavy for that aircraft).
 About any engine other than a two-cycle engine tends to make the Avid nose
heavy.

 Operating on a grocery-money airplane budget, I am hoping to do much of the
conversion work myself (sans critical parts, of course).
 I think I'd like to stay away from the turbo, if possible and keep things
simple. That is if I could squeeze out the H.P.
~ 90 h.p. sounds O.K. if I could keep the all-up weight shaved way down.
.....will keep checking out the possibility.

This is what periperal port rotor housings look like.
