How can I increase the horsepower of my car (1995 Eagle Talon 2.0L 4 cyl.) without spending too much money?

Well it depends on how much money is to much for you. Cheap up grades might be a cold air intake, computer chip, headers, high flow CAT or no CAT, Muffler to list a few. You can improve your existing HP by changing to solid motor mounts and trany mounts, better plug wires and plugs. Dont waste your money on little do dads off ebay, most dont to anything.
