    FAST fuel rail question

    I am thinking about upgrading to the FAST 102 intake. If I do this I am going to put in 42lb injectors as well so if do the injectors can I just buy the fuel rail and save $100 vs the fuel rail kit with spacers?

    Do you have a need for injectors?? For that matter....need the rails?

    42# injectors are basically the same physical size as stock.

    Heads and cam still on the stock injectors. I need to go back to get off the street tune. ws6store helped me out but for the fast intake they say you need to use there fuel rail with spacers to make em work or something like that

    Are you running stock cubes or a stroker setup? Not sure if the 102mm requires what you're talking about on an LS1, but I do know the 92mm doesn't need aftermarket rails or spacers, and if you're stock cubes with just H/C, then a ported 92 will be perfect.

    this will tell you everything you need.... the injectors themselves will be the same size unless you start running ls2/ls3/ls7 style injecotrs but then it gets confusing ...just click on that link and it will tell you everything you need to run it.
