I've wanted to soup up my motor for a while but i didn't want to turbo it because that's alot of stuff involved but the other day i rode in a turbod 240sx that makes 330 hp.
That inspired me.

So onto the questions.
I've got a 95 si. Which has 160 hp. I plan running 17 to 20 pounds of boost becuase i'm shooting for 300 to 500 hp.
I thought about buying an h22 but that costs money then it would be more money to rebuild it for the seventeen to twenty pounds of boost i want to run. So therefore i've decided to rebuild my motor with all aftermarket/upgrade pieces, the whole shabang. Which should give me a 100 hp gain right? So then i'll have 260 and since i'll have alot of boost it should shoot me into 400 hp right? What are some other ways to eek out some hp so i can break 500?
Am i overlooking anything?
Any thoughts or opinions?
