H22 or H23 will be your best bet, but only if you want to stick to NA tuning. Keep in mind your car won't be a rocket with an H-series motor in it, but it'll be significantly faster and is much more suited to bolt on upgrades. It's the whole 'no replacement for displacement' thing. They have ~200 crank HP from the factory. But a built F-Series motor with a well tuned turbocharger on it will get you more than enough speed if you want to go that route.

I don't want to discourage you from modifying your car, but if you lay down a grand on simple bolt ons like most ricers do I don't think you'll be pleased with the results when you could have put that money towards forced induction, a better motor or a better car.

I'm sure there are plenty of posts in this forum and the Hybrid forum for you to look at for more info.
