well now that i have the b16a ive been after for almost a year i need something else.its just lacking something.its fine when im by my self but when i get one of my friends with me its just lagging cuz of the weight"big guys" so what should i do. i dont have the money for a turbo i dont want nos and a supercharger is just outa the question.i was kinda thinking i could beef up my fuel system . 1.AEM fuel rail 2.bbk fuel pump 3.venom fuel injectors. 4.later some kinda fuel controller. i.e "vafc,vafc2,venom 400 controll module. would this give me some decent improvements for power? would it affect my idle? or should i just get a cam.if i get a cam then do i have to replace all my valves? i dont have much money to go around so im looking for something not to expensive but with resonable power.i was kinda thinking of going with the cam.i dont know what kind or brand but.
