Wow, congrats! A Zetec-er finally did it! Welcome to the world of Turbos...just warning you though, once you go turbo, you'll never be able to enjoy a N/A car ever again. What size exhaust are you running? How much do you have invested?
You should check out Turboford.org...its mostly 2.3L stuff, but there's alot of general turbo tuning tech that gets discussed there that will apply to every application.
