I have a 93 SOl SI SOHC vtec, and I was wondering about a few bolt on's.. I have so far AEM intake, DC Headers 4-2-1, Greddy SP exhaust, and AEM high flow fuel Rail. I want to put a intake manifold... will it give me any good power gains and which should i go with. also which throttle body? Next i wish to put aem fuel pressure regulator any use?? I plan on turbo soon no high boost just 5-7 psi. should i put a cam gear or anything else? give me your oppinions on what bolt ons i should do before the turbo I wana do all the bolt ons i can before i turbo it. thx
