| Here are the stage charts for your perusal. La-Z-Link Scroll down for the NA stages. Generally people follow the stage charts for upgrades, give or take. Keep in mind stages only include HP mods, and don't cover things like suspension upgrades, brakes etc. Any kind of true "twin" or "dual" intake system will not benefit your NA (at least at this point). Stick to a traditional single pop. If you are referring to the ebay kits, they are single pop, only the plumbing is "dual". My vote is to always do maintenance before anything else. You have a performance car, and it is going to require a fair amount of upkeep; even on an NA. If you haven't done the 60k service I highly recommend doing it before anything else.
