NOT time to get a fuel pressure regulator. They have their place but they only complicate things and are not needed/should be avoided until you are making so much power that you need a 255lph fuel pump. I am running 20-22psi on a big 16g turbo with 680cc injectors and a 190lph fuel pump and the stock fuel pressure regulator is just fine.

 

a lot of people have told me not to put cams in my gs which is a idea but if i am trying to make a high compression all motor car "N/A" i have been told to get bigger cams. would i need a bigger fuel pump as well?

 

I would say no. Cams arent going to need THAT much more fuel. What you really should do, is get an SAFC and take it to a dyno to tune it. With bigger cams you will be moving more air/fuel into the engine. Tuning will get it to run better and give you more power.

 

now i am overhauling the motor. boaring it out .25 bigger pistons new hardened rods and so on. i alreay posted this but with the overhaul of the head and the bigger pistons all that fun stuff i should be fine with the stock pump right.
