Hello I am currently working on a turbo buildup project. I didn't have much luck at focaljet on getting information on the differences between the zetec pre focus. If anyone could tell me even the smallest details would be much appreciated. I just want to make sure I don't spend too much money and find out that I will not be able to use this motor. Also is the crankshaft the same as i'd like to stay stock in this matter as this motor may well be seeing 300 hp. Should I replace the maincaps?
