since im new to preludes i figured id start small and go with basic boltons and some headwork like new cams, polishing etc... Probably i wont do any external mods, maybe tint job. I pretty much like the whole way the car looks as is, i think making it look stock will leave the wannabes' guessing when i show a timeslip that blows anything they could do away . I hear of a vafc? what exactly does that do? controls air fuel flow for vtecs? how well does that help a engine that is not turbocharged?
