I'm looking at a few cars for a track day car that I can abuse.
One of the vehicles I'm considering is an older Mazda RX7. The primary reasons being that it has a rotary engine as well as the curb weight, which is very low.
I like the idea of the rotary because if I over rev it by downshifting to early that the engine doesn't have any poppet valves to destroy. The performance profile, other than weight, isn't a giant concern but I want to do something to it to get a little more umph out of it.
What are common modifications done to the Wankel engine to improve HP?
Do common engine improvements to a rotary engine such as port timing modifications provide the same benefits to a Wankel engine as a normal piston engine?
