EA71 engine performance

Recommended Posts

Guest subarugsr

i am about to buy an EA71 engine for NZ$80 (US$40) it runs well and is tidy. I am wanting to 'hot' it up. could anyone tell me what can be done to these engines to recieve optimum power? a turbo could be an option. ive heard the EA63 duel port heads fit on the EA71 but the cam needs to be swapped over for the inlet, outlet valves, can anyne confirm this?
