Asking a serious question here I bought a 2014 fusion se 2.5 fwd from an auction got a stupid deal on it 100k miles runs great, I want to swap the 2.5 n/a fwd out for the 2.0 ecoboost fwd engine/ecu,harness I seen both se trims look identical inside and out and both engines use the same exact transmission I was wondering how possible is this ? Seems like it should work also what are some other things I may need to keep the car running decent ? I got the car for 1800 bucks so I. Not really try to sell in go buy a car with a 2.0
