I don't know too much about SCCA and all, but if you want to know how to make a race-ready Zetec, go to
Zetecinside . The guys on that site are over in the UK, and have put together one HOT Full-race Zetec Fiesta. Because they used a 2.0L Zetec E like our U.S. variants use, almost everything they did is possible for us. It's worth a look, and you're bound to find something you can probably use along the way. The website also provides a plethora of websites and sources to find things that just aren't made for our cars over here. I strongly recommend the site.
Hope that helps you out a bit.
