It's in a ke25 so will be thinking of running the samq water and ignition conversion kits. The motor I have goes strong and there isn't much wrong with it but came across the blacktop cheap and thought could be worth a shot without having to recert etc. I appreciate a fairly worked 16v but I think it will cost me more money to gain the power the blacktop will produce. How many hours and how much money would you expect to pay for someone to tune a 4age with aftermarket ecu?/link?
