Ok guys/girls, I am a big time speed and power freak. I have done up many vehicles in my time. Now, I have a 4 cyl. Fusion. Not exactly the definition of sport, but because of my new circumstances I needed a vehicle for going long distances and getting good gas mileage while doing it, and it has to be a FORD...!!! The question I have is, will the performance parts from the Focus 2.0/2.3L engines and Mazda 2.3L fit to our vehicle. I have seen a bunch of go fast goodies on sites like focussport.com and it gave me a warm feeling knowing there is hope out there. BUT, will those parts fit on my 2.3L engine? The engines look exactly alike, the engines even have the same name, Duratec...WILL THEY FIT...? Has anyone tried yet...?
