Well, I was in the same situation and I have $1,000 left plus the mods listed below (sans brake pads/rotors). Now that I look back on things I really wish I had $4,000 more to spend on forced induction. But I'm happy with the way the car looks and handles.

Chassis + appearance = greatest satisfaction. Once you start opening up your engine and seriously bumping up power levels you'll enter an entirely different world.
