basic mods

Get tires.
Get a lid, doesn't really matter what kind you get.
Get an exhaust (don't get flowmaster), or opt for the even cheaper cutout, or electric cutout (quick time performance).
If A4 then Torque Converter.
Those are the basic mods.
ASP Pulley, ported throttle body, all those add ~8hp, but don't cost much either and you can install them yourself.
If you want even more cheap HP, nothing beats nitrous for the money. Headers are also a great mod, especially with nitrous or a new cam.

ls1howto and ls1university have good write ups. Most won't cost much.
efilive 6.3 is pretty cool will give you a good know-about your car, you might be suprised when you datalog the knock retard and misfire's on all cylinders
Get an airlid as your next mod followed by some kind of exhaust. The free mods are pretty cool if you don't mind hacking your car up a little (like the airbox).
