Every airplane and every powerplant seem to have unbelievable claims for 
speed and power. I hope you folks can help determine
honest expectations.

I'm wanting to achieve 200 mph cruise and 15,000 feet; best I can tell 
the power requirements at 5,000 feet would be
approximately 170 HP with turbo to maintain speed at altitude.

Is anyone doing this now?

Everything is a supertight budget (isn't everyone's ?) so the 
PSRU and intake manifold will have to be home fabbed but Tracy's
fuel and ignition controls are on Santa's list.

Can anyone tell me what a complete rotary installation, with and
 without turbo, with and without OEM muffler, with oil and
coolant, will weigh?

Be prepared for lots of info requests.......expect to buy engine first of the year.

Thanks for leading the way.

I think that speed is easily doable. Try to find an 1989 or 1991 Turbo II
Mazda RX7 motor. Without turbo you are looking at about 320 pounds
firewall forward. Take off for the muffler and add the turbo 
roughly another 30 pounds.
