Over the winter i will be installing my JPWORKZ 6266 kit, VRSF 7.5" intercooler, VRSF 3.5" exhaust, and Docrace intake manifold with port injection looking to be around 700-750whp. The only thing im unsure of at this point is fueling. I will be running full e85 and know i need the fuel-it stage 3 lpfp. Will i need to convert to a full return fuel system at this point or just upgrade the stock line? Also what injectors will be needed for port injection, since the Docrace manifold does not include them.
