> What are the benefits of a Wankel Rotary engine over a Piston Engine? Lets say I were to swap in a motor into a random frame, what would make me pick the Rotary over the Piston engine if I wanted to make either of the various cars

-Light weight  
-Its “smaller” size easily allows you to re-locate the engine behind the front axles. Allowing for better weight distribution.  
-IIRC, 2 or 3 moving parts in a 13b rew  
-Relatively cheaper to build for high boost applications, when compared to PE’s  
-If built properly, it can run at max rpm all night long
