Sometime next year Im thinking of having a Duratec 2.5 engine put in my Contour. I can get a used one at a junk yard with low miles for about 5 or 600.00 but would not be able to install it but have a guy here in town that will do the work for me. Would I need any other parts when doing an engine swap, Im assuming since I have a zetec now that I will have to have a new computer, but are there any other parts I would need besides the complete engine? Im not looking at doing this till about May of next year. My tour is getting alot of miles on it, it still runs good but I want more power.
