Horsepower is always expensive. I recommend taking it slow and replacing things only as they wear out. As the old saying goes, if it ain't broke, don't fix it. If it IS broke, fix it with a good quality performance part. Any major hp upgrade, like a turbo or a nitrous kit, is going to need a lot of additional parts and attention to keep your car running right. It can turn into a black hole, and skimping on the parts or the tuning can make a reliable car go dead in a hurry. Save your money so you can buy quality performance parts when the OEM ones start to go.
