I think before you start dumping a lot of money into this car just drive it and get a feel for it. Power at the wheels is around 270-290. If you want more, then the easiest way to do it is forced induction. Just be aware that more power equals more heat. If you want to play it safe, then go all motor and shed some weight if you intend to track this car.
I don't track my car, so my setup is plenty fun as it is right now. Keeping it clean from bird doo doo and chunks of asphalt is difficult haha.
