New Fuel Pump And More

[335]

Hello

I am getting a new fuel pump soon to replace my old one. I have everything stock in the car except for a catback exhaust and pod. If I get a bigger flowing fuel pump do I need to change the injectors or get the car tuned?

Thanks

Help

A new pump won't need new injectors or tune. You only do those if you're upping boost or doing other mods.

Just make sure the pump (depending which) gets some decent voltage (above 12v to my understanding) and it'll run all day.

Tune will be the next step. Injectors if you change turbos.

^yup

Fuel pump and flow is like Girl Scouts knocking on your front door trying to hock cheap cookies.

The number of em can increase, but it wont effect your wallet... as long as you don't open the door (injectors) lol

Oh do I need a fuel regulator? The pump I am looking at is the Nismo one which flows 4.1 liters per min I think.
