Get creative and make stuff on your own. i.e. home made intake instead of $100+ one, flip motor mounts instead of getting 75 dollar ones (you can worry about those polyurathane ones later down the road if you want), and the one thing i love doing it taking parts off other cars, in my case it's taking parts off of Audi TT's to put on my GTI, but any other W-body car woudl work for bigger brakes, strut bars, suspension and different engine parts, and you can get most of them used so it's cheaper. Just go look around online and if you find something you like, think about where you could get it elsewhere or if you could make it yourself. Trust me, it will keep you on a good budget. Being a college student myself, i know how it is.
