i have an s5 turbo with a custom 2.5" straight pipe and a cone filter, ac,ps,omp and all emissions removed and i wanted to know if a walbro 255 fuel pump is going to benfit me with the minimal mods i have on my car. i can get a bran new pump for 80$ and will buy it, if it will benefit me. My car is parked for the winter right now, before the spring i plan on an fmic, a boost controler and a fcd.
thanks,
ben

 

it wont make too much of a difference right now with how you sit but if your preparing for more boost and an fcd I wiould buy it for sure. YOu will also need some 720 injectors and at least an safc if you plan to run 12 psi or so which I assume you do cosidering your getting an fmic. Go for it for sure. its better to build your fuel system before you boost higher to save the motor. thats what I did.
