Im curious to know how and what do injectors do cause I havent really heard much about them. Of course they make feul flow better but when and why would you change them and for what setup. Im doing a b20 turbo set up and saw the rc injectors and was wondering about it. I mean even if I did all motor would I have to or should I get new injectors. Also what kind of results would I see and in what range. Your opinions are appreciated.
