Welcome. Try searching in the forum and you'll get a lot of information. At the top of each forum, there are stickies which should be read, and will help you with the basics. You can also do a search in say (if your car has a 2.5) in duratech performance for "exhaust" or "intakes" or whatever regarding the engine. (same applies to the zetec forum)
Thats hsould keep ya busy for awhile. Remember when doing a search, be sure to mark "all posts" and not just the ones from the previous 7 days.
