I have some very basic questions.  What is the output RPM?  What is the
 weight of the engine and any required PSRU?  I read RPM's from 8 to 9
 thousand and yet output of 2000.  Is this with a PSRU?  As you can tell,
 I am completely ignorant about rotaries.  My first decesion is, can
 I, or
 do I want to, use a rotary to put in my KR?  I am assuming the weights I
 am told will include all the necessary accessories including a PSRU if
 required.  Any help will be appreciated.
 Thank you,

 Up to 11,000 RPM. But we uses only 7500 and a 2.85:1 PSRU.

 240 pounds for p-port 250 HP part cast iron engine.
 No cooling or exhaust. With 40 pounds PSRU.

 190 pounds for p-port 250 HP with aluminum end and center housings.
 With 40 pounds PSRU.

 Don't even think about side ports. No suitable intake manifolds
 available. http://www.rotaryeng.net/fund-of-intake.html

Technically you don't have to have a PSRU, you just have to limit the RPM.
The two rotor 13B at 2500 RPM would probably have plenty of power for a
KR2, if it's not too heavy.
An 0-200 weighs nearly 200lbs.
Although it seems like just a lot of engine for a KR2.
