sweet man, i am about to rebuild mine. i plan on boring it out .030 over, shaving the head, with a 2" exhaust system. i have a holley 5200 carb and a weber carb that i want to rebuild and see which one i loke most. other than that i don't know what else to do to beef it up. i could get all kinds of expensive internals but i don't know if i want to go that far. a guy i work with has 2 first gen rx-7s that he is building to race. one is a parts car. i think just like you with keeping the 4 cyl due to gas mileage. what all have you heard on beefing these engines up?
