the only rotary engines that are in planes are in expermental planes, like home builds (Vans aircraft's RV series is a really popular platform for the wankel.) And since putting rotorys in planes is a new idea, there wont be any in a junk yard. Also, they are all flying Mazda 13b's. And theres really nothing different from the aircraft engine VS the ones in our cars. Powersport makes one thats got a small PP with an intake thats designed for a very specfic RPM. It makes some great power at a low RPM, and could possibly be streetable, but they want huge cash for 'their' engine.
if you wanted a true bigger engine, you would have to find one of those super rare experimental chevy rotarys. Even if you found one (some guy on this fourm got rotors from one) it would be a crime to run somthing that belongs in a museum. The engine was huge at 3.3L
it was a 4 rotor i believe.

Maybe I'm just talkin crazy, but wouldn't you have problems with trying to line up an engine with larger rotors to the transmission? eg. larger rotor = larger diameter = won't sit as low as the original = won't line up with tranny. Not to mention it may not fit in the engine bay at all.

They've used them in airplanes for a while, except as OC stated, they're built for a specific constant RPM, so there powerband isn't designed for a street car. Check out the skycar and other designs by them (just search google for it) I want one of those!

Aaron: those radial engines (sometimes called rotory) are used in most, but there's quite a few that actually use wankel's rotor design. Most commonly for craft that hovers.

Kai: Yes, that is a real engine.

There is a rotary engine that is made with pistons althaugh very rarely used, they were used very rarely in WWI, as the setup of the radial was verry similar but instad of radial cranking a shaft on the rotary piston the crank shaft stayed the same and the pistons turned arround it. I think this is what Aaron might have been speaking of!
