Looking for info on tuning 93 mx-3. I have a 1.6L sohc with 287,000 miles. I'm going to be rebuilding the engine completely and am hoping to get some power out of it. can i do a dohc swap directly or do i need a complete engine and ecu. The engine still runs well other than oil leaks and a little smoke when first started. also considering a rwd swap from a miata or an rx-7. any tuning info would be welcome. Also are their any other mx-3 owners in Western NC on this site?
