do some searches around the forum and you'll find a LOT of information about modding the car.

Without some more major work, it would be hard for you to get any sort of good boost from a turbo kit, because of your high compression ratio. Lowering the compression ratio of an engine would allow you to run higher amounts of boost pressure, but in this case, it would involve some not so simple modifications to the engine.

as it stands though, you could go with the basics: intake, headers, exhaust, ignition, lighter wheels/high performance tires (dont give you more HP, but allow you to handle the power better), suspension...you name it, you can change it.

think about stuff like what you want from the car, what kind of performance you're looking for, and/or how you want the car to act, then go from there with the mods.
