Will stock fuel pump be sufficient or will aftermarket work wonders. I will be running stock injectors, stock motor, k-pro on a k20a2?
The stock pump will be fine up to around 300 whp.drhonda said:Will stock fuel pump be sufficient or will aftermarket work wonders. I will be running stock injectors, stock motor, k-pro on a k20a2?
I beleive it will run fine in the lower rpms. But once it gets to the higher rpms the fuel pump can't handle the extra fuel. Since the FPR is pushing more and more fuel into the motor and the fuel pump won't be able to keep up. So i bought a walbro 255lph fuel pump.adirondackR said:what about stock 99-00 DX fuel pump? (sorry I don't know if thats any different from RSX stock fuel pump)
well, for my swap... i was running without a aftermarket fuel pump for awhile and i would notice when i get to speeds of higher than 80 mph on higher rpms, the car would stutter.... i picked up a edelbrock intank fuel pump, 255lph... ever since then, the car would pull hard all the way up to each gear.... i would recommend getting a fuel pump for sure
