I am thinking about getting the hks turbos and not proting/polishing and maybe skipping cams for now. Just putting in better valve springs and retainers and stock valve seals. WHat about balancing and blue printing the motor? I have no idea about this? Is it worthwhile to do and how much does it costs? I want 500 RWHP at least but i am willing to sacrifice a little power(and the money need to get that estra power) for longevity and reliablity of the motor. I also need to know the best rod main barings I need and what is swain coatings?
