I agree with yadefine alot of money, lol, whats ur budget. NA, the zetec is hard to get faster, it costs alot, you can do basic boltons if you want, but not too much more. for FI, ur looking between 2-5k for a good setup. my advice would be suspensin and tires. stick w/ them and you will have an amazing handling ride!!
if you got motives, you can actually make ur own turbo... using old parts. stock headers and do on.... someone here make there own turbo running about 8psi, and it was less then 400 to 700.... becaues he did the work him self..
i know the thread is in this site somewhere.
your both right, look up "jeffescort" that is the guy. some of the parts i belive came off a escort as there were turboed models in the 90's^^It was on a SPI motor. He did the complete kit for $400 or so.
