I did some searching through through the threads but was unable to find what I was looking for. I plan on pulling my motor and "building" it. One thing im not very knowledgeable is the fuel system. how big of injectors can i go without being overkill. i plan on upgrading the fuel rail but i dont know what to go with. or what fuel pump to go with. Can you put say 120lb injectors on a stock motor without doing internal damage? I currently have a e303 cam stock heads as far as i know:/ typhoon intake, 70mm throttle body, hooker shorty headers msd ignition...im new to this and this will be my first full engine build
