search man this same questions has been asked. if you want real power you will need port polish the throttle body, intake manifold, 50 shot, turbo, internal work, and more.

ummm......i can't really think of anything else "bolt on" that will give u the gains u want. But the bolt ons that u do have will work great in combination with a turbo.

i was thinkin somethin no more than a couple hundred bucks, pulleys? cam gears? intake manifold? how much does port polish, balancing, blueprint, valve springs, retainers, all that good stuff cost?
