fuel system question

[josherino]

ok so I installed an safc II and also have 660's and a walbro255, which are not on the car yet. the safc is zeroed out or stock right now. my question is I am still on a 14b and I am not sure if I should put the 660's on yet. I don't have a fpr, but I live at a very high altitude and most do fine without one. I want to put all this on before i put on my evo III turbo, but I need some input on whether or not I should do this.

Regardless of your altitude you will need a FPR to run the 255 properly. Without it you will be over running the stock FPR. You can put the injectors, AFC II and pump in with the 14b. This will not hurt anything if it is tuned properly, and you have a FPR for the 255 pump. Hope this helps

I would put it in. You dont want to overwork any part of the car. You will need the bigger injectors to keep up with the 255. If you do one part of the fuel system, to me that means go all the way with it.
