I'm about ready to start putting my motor in and piping the hotside of the turbo. I have some of the piping still need to get the flanges but pretty much know what I need there. I'm trying to get the rest of my parts list figured out now. I have a 68 Camaro that I'm putting a 5.3 in with a 75mm B/W S400sx3 turbo. My biggest questions I have now are for the fuel system I plan on putting a sump in the stock tank and running an A1000 external pump. I'm not sure what size lines I should run for the supply and return or what regulator and injectors I should run. I was thinking of running E85 but its not very easy to get around here. The motor is stock and I'm wanting to get around 550-600 whp and try to get the car to run 10.50s or so. Do you have any suggestions on the fuel system and tuning? Thanks
