Can replace engine from 2003 ford focus 2.0L with 2007 frd focus zx4??
Honestly this is a difficult one to answer. You will prolly have to check to see if the motors have the same motor mounts . If yes then check if wiring harness is compatable with the vehicle you want to put it in . And you also have to see if you even have enough engine compartment to compensate for the different engine which that in it self will tie into the motor mount issue. Hopefully this helps you . I'd also call your local ford dealer see what they say if no help there then try a custom auto shop...
