You are going the wrong way, you can gain a fair amount by changing injectors and getting a reprogrammer for the on board computer system, then you can add in a cat back exhaust, fresh air intake system, if you want to get serous about horsepower gains you can change to higher compression Pistons, larger valves or different heads completely.

I agree with tennishoes completely!! Try the reprogramer route first....
