I had a pre-miata mazda, a 72 rx2. I bought it for $100 with 60k miles and I rebuilt the rotory engine. 16 mpg was typical 18 was good. It would rev so much there was an alarm on it. Unfortunately I put the minimum clearances in the side seals and one cracked after I over revved it to 9000 rpm. To get crazy hp, all you have to do is grind the ports bigger.

Guess which one is the rotory:
