Im not too knowledgable on selecting injectors. Would I have any drivability if I stepped right up to 75's. this way when more mods come later on they will handle it. basically just have a 925cfm turbo,mild cam,headers,3inch exhaust. plugs are burning super clean,actually looked unused when I spun them out the other day.jwaller said:stockers are red tops and they sounds like marbles in a car. very noisy. swap them for some 50's and a good chip.
