Throwing all these parts on your engine is a good start but I think you want a more kick in the pants performance upgrade and these really aren't going to cut it for what you're looking for. If you're serious about getting more performance, you need to think about getting a NW dual and a tune in addition to the upgraded TB and injectors. Forget about headers as they're not happening and stick to the tried and true stuff. It's out there and it does make power. Rob @ NeedsWings tests everything so you're not buying vaporware. He can get you all the parts as well and you'll get a fair price on everything from him.

Good luck with your quest for power and if you're still wanting to toss that 320 motor off a cliff, give Paul or myself a shout and we'll get you setup with something that will make you the envy of the neighborhood.
