I would NOT change the pump from the stock setup unless you are going to forced induction (turbo or supercharger). It is a real pain to swap out and you just don't need that much flow with a stock setup.



Most of the guys I have seen using the 340 and up are also using a return line fuel system and those guys are running lots of boost and or E85. The 255 Walbro pump is good up to 450-500hp. Beyond that you will need to go to the 340. If you run E85 and high boost you will need the 450.


Well I was considering on doing the e85 conversion but staying NA for a while. At least till I can get some cash to pull of a TT or SC kit. I'd like to stay as stock as possible and whoop a$$, feel me?
