Hi, I am come from the land of carby's where if you want performance you wack a webber on. so with a 1990 corolla, what is the cheapest mod for performance? They have the 1600cc engine or 1.6L engine. I imagine these cars are computer operated so therefore I am guessing you could stick in on a computer and "mod" it? I will also read other posts as i am sure this has been asked before. Any help or info about these cars would be great. Oh and mine has done 200 000 :o is that bad? thank you
