What is the difference between the Mazda engine and the Ford engine (which is supposed to be the same 2.3L) used in the Fusion. I noticed that it has more HP and TQ at different RPM than the Mazda.
Looking at the spec sheets you would think they would be the same. (9.7:1 CR, VVT on intake, etc) It's only 3-7 HP difference, but I was wondering why. It is just intake and exhaust? Or has Ford tweaked the ECU for a bit more?
