but i want to know if i put a turbo in it will it damage the engine, i mean what type of changes besides going faster will my car have. if putting a turbo in it will damage the car then forget it. i still need to put a little more power anyways so if anybody can tell me it would really help.

If you don't do the turbo job properly you can do some serious damage. If you do it properly, it will be a pain in the butt to keep everithing running right. Had a factory Turbo Grand Prix, ran very quick till the bottom end of the engine gave up. Had a Audi Turbo, much better engineered than the Grand Prix, but too complicated and a maintenance nightmare starting at 75K miles.
