I removed the restrictive air resonator for free
That's about all I've done so far, money's tight in college. Once the winter is over, though, I'm going to get 4 7-spoke 15 inch Escort GT wheels and put 4 new summer tires on them. I'm also going to get some front turn signals off a Mercury Tracer, they are the exact same as mine except that they are clear with small orange reflectors instead of solid orange.
