Ok, I bought a set of pistons and rods for my car. I am planning on running around 1.2 bar which should put me around 300 horsepower but I need to know what I should run for my new fuel setup. I currently have RC 440 injectors installed on the car. And I also bought a set of RC 550 injectors for when I am boosting at 1.2 bar. But I think I will be needing an intank fuel pump. How big of a fuel pump will I need for the 550 injectors?

 

Go with the walboro gss-342. That's the 255lph high pressure. Paul
