So I would like an opinion. Should I consider a rotary option.?
If so...could I get by with a carburated engine? What port option(s) would
be recommend? I want to keep-it-simple.

The p-port is the simplest way to go. 200 HP with a Holley 500CFM carb is
no problem. No custom rads needed. Any number of auto rads will work with a
properly designed scoop and duct. I have a book called "How to Cool Your
Wankel" you can buy at AC Spruce or Mazdatrix.

Thanks for the concise answer.

What do you suggest I start with for the basic engine (block? - whatever you
call it)

R

Any Mazda RX7 or RX8 engine starting in 1989. The later the engine
the more the cost.
