Well, so far I am thinking of heading down the turbo road with my Zetec...but I was wonderin if going to a 3L Duratec would be a good decision...i'm guessing I would need a new tranny (right?), but I was thinking of a Stage 3 turbo for the zetec, which would run me some money, so i'm wondering how the price for tranny and engine and what-not would compare to the turbo?
or are there any other engines that I can swap?
