What should I use for fuel pressure regulator in boosted setup

[doug.gardiner@gmail.com]

I have a 1990 convertible that I am building into a boosted setup using a precision 6262 turbo. All the intercooler stuff, is done. The turbo is mounted. Oil lines are routed. I also replaced the fuel pump in the tank with a Walbro 255. I have it set to use maximum boost of 15 lbs. I how would I setup the fuel pressure regulator to overcome the increased pressure?

I should also add that Im running 60 lbs injectors, as those were upgraded as well.

Couldn’t tell ya. But I bet the guys in the Engine & Drivetrain > Forced Induction section can 😉

Stock FPR is fine until you start flowing too much fuel for the FPR to bypass.
The point that happens depends on your fuel pump (Not power level or boost), and a Walbro 255 is not going to give you that problem.
The big sign that this is happening is high fuel pressure at idle (or needing to pull more fuel out of your idle fuel map).
