hey. do i need to run an adjustable fuel pressure regulator on my stock fuel rail on a jdm gsr that im about to turbo. im using a walbro 255lph fuel pump. will i burn it out if i dont increase the fuel flow or somethin. im using 550 injectors also if that helps at all. thanks

 

I cant really give you a good answer because I dont know.

But i've been running a walbro 255lph with stock fuel rail and fpr on my car for almost 3 years without problems.

Im also running 550cc injectors.

I dont know if its luck or if I should get a fpr too.

 

You'll be fine. Whats the setup gonna be? Pretty conservative, 6-7lbs?

 

you really dont need a fpr until you start to see pressure drop mostly in higher horserpower car that need a 1:1 rising pressure
correct if im wrong anybody
