OK there seems to be some confusion going on here. First if you want to turbo your car, DO NOT spend the money to get a Cold air intake, headers, or exhaust right now. The reason being is after you turbo it those things would be off the car. I would only suggest 3 turbo kits for your car. They are the Turbonetics, Greddy, or Edelbrock. They are in the $3,500 price range. Now this may seem like alot at the begining, but the cheap kits that you find on Ebay and places like that ARE NOT complete reguardless of what they say. You will ALWAYS have to buy parts with them. Plus they don't have fuel management which if you turbo the car, and no fuel management it goes BOOM!!! Now to put it into perspective the AEM intake, Greddy Exhaust, and DC header would put you at about $1,000. You would see gains of about 13-17 wheel HP with this combination. The turbo kit would give you 80-100 wheel HP now broken down in dollars per hp thats a MAJOR difference.
