colli

okay guys, me and a few mates have a little competition going. we have set ourselves a budget of $500 to spend on getting a car and modifying it. then we are taking these cars to an undisclosed location, and having a series of little comps. well, ive pretty much purchased a ke70 corolla which is going to leave me with $300. now. i was thinking of removing all interior and any hanging panels. is their anything in the engine bay i could remove to gain some weight back? also, i have a air filter laying around form a 4wd race car, would this be two big for the little 1.3? also is their any cheap mods i can do to get this thing moving along?

anyone else going to come down, its tomorrow night
