If you have thousands of dollars go for it, otherwise forget it. You could easily get thousands and thousands of miles with a 200+ Zetec, but in the end it is going to wear a lot faster since it is doing more work. And you also have an ATX, the POS was not designed to even handle 200HP. But if you are still interested, forget about your engine for now and get that tranny bulletproofed. You'd probably want it to be able to handle 225HP just fine...even if you are only going to put on a 200HP kit. Then when you can afford it after playing with the tranny, you could go ahead and get a 200HP Turbo Kit. Don't know why you would want more, it would be more expensive and further wear the Zetec. They should totally rework the intake, and give you new headers, but you'll have to upgrade your exhaust system to 2.5" pipe to make up for the HP increase. Cheers.
