a good first step is to swap to Multi-port fuel injection.

its a dx, you need to swap the entire intake manifold, its not easy, and it isnt hard to do either.

You'll need to get an Si intake manifold, injectors, and a fuel rail. Then wire up the MPFI harnesses.

you will in no way see a 20-40WHP increase in doing the mpfi and head swap, you might catch 10-20 at the motor at best, maybe 5-10 at the wheels.
