Just bought a 2003 evo 8 and loving life so far!! It sits at 361 hp to the wheels at 25 psi. Was wanting to get to about 500 hp at no more than 32 psi. I already have a little work done to it like walbro 255 pump aftermarket turbo intercooler and forced induction. Just looking for some cheapish suggestions. Anything helps. Thanks.

Welcome.

First, I would suggest reading since your questions are not exactly straight forward, nor are there straight forward answers.

If you wanted my specific advice, I would tell you unequivocally to leave your car exactly as it is (provided it has a proper tune) and drive it for some time. Read about various options you have for it on here, and decide what you like, what you don't like. What you feel can be improved, and what the general pitfalls of owning a 500hp Evo 8 could be.
