Can someone help me out with some cheaper upgrades, with the stock 160 hp the prelude's quick, but of course it needs to be quicker, i have full ractive exhaust, from the header back with a high flow cat, a ractive intake, and i'm not really sure what else there is to do without getting into cams and camgears, i hear from some cam gears are important and from other they're not, also racing pulleys i hear are aight but i also hear they don't do anything, i'll go with aem anything along the lines of pulleys and cam gears, and can someone tell me what the fuel rail does and why you want to upgrade it?
