if i mini-me my engine w/ d16z6, what are the critical parts i need to replace? cuz i've tried searching mini-me procedure, but one post and another are different. some say, valve cover, distributor, and ecu. other says cam, timing belt, wires, and plugs. some even say to rewire the whole thing.

also, does it matter if i get valve cover from good engine or bad one? cuz i know a guy who has a dead d16z6 motor and he's about to throw it away. can i use those parts?
