So with VCT can you upgrade the cams? I'm toying with the idea (don't have the money) of getting crane cams and the lighter cam pulleys. Can I even upgrade the pulleys without screwing something up that really SEEMS to limit the car? If it controls emissions then it probably doesn't allow something else to work at its best.
As far as swapping engines, I think it is a good idea. There are way more parts to play with.
Go for it but use the SVT Focus motor. Have you seen the specs on that thing?!? Although you might have to swap the tranny too.
