Well for starters you need to free up the exhaust. The exhaust is very very restictive on thses cars, a cat back system, high flow cat, and some headers will really give you a boost.

I second that on the exhaust, go 3" all the way. Put an open element air cleaner on it then get gears and posi. You can get a posi carrier from SLP for $99 then most guys go with either 3.42 or 3.73 gears, your choice. That's a good way to start off with our cars, then if you want to spend the money get into heads, cam, and intake. Also, check out the technical articles on this page, some good stuff there.
