fuel system help first time ever building a turbo car 99 ls1 Camaro. I need help choosing a fuel pump if I need a single or dual. not sure how a hotwire works. do I need to mess with the fuel rail at all. I know upgrade the injectors but I don't know what size I need. I might need guiding on how to plumb it if I need to. like I said major rookie on building a turbo car

Alright, for 600HP, a single Walbro 255 with a hotwire and Deka 60 injectors should get you there. A hotwire simply provides a higher voltage to the pump therefore increasing output due to running a power connection directly to the battery (roughly 13.5v) vice 12v supply from the PCM. You can most likely get away with this on the stock system, including stock rails, but a lot of information is available on running new fuel lines (recommend -8AN supply/-6AN return) in which case your fuel system will be built for any future increases in power goals.
