well today we tuned up the b16 STD hatch, and my plugs that I have been racing on, looked brand new still, and my car was running really slowley and does not rev like it should, so i know i am starving for fuel from the STD pump, someone gave me a LS integra pump, which of course does not fit, does the Si pump flow aymore over the STD pump? i have one of those also, i just dont have the money for a walbro right now

 

im doubting it is your pump.

make sure all of your injectors are even working, since most dpfi-mpfi swaps arent wired up securely.

 

LOL that is funny, i work at an import performance shop, i know that my injectors are working, all 4 of them, or the engine would not run a smoothley as it does, i know the when a motor is starving, for mine, it is a combo of only having one O2 sensor, and the STD fuel pump, that pump was made to flow fuel for a 1.5 liter non-vtec 62 HP engine. trust me, more fuel + good things, i was just wondering what others used other than holley, and walbro
