Hi guys. I'm currently building a budget spec, low boost (7-8 psi) stock management M50b25. I know It's not the ideal way to reliably turbo the car but it's the way it's happening for the time being. I'm going to be running a high flow fuel pump (Walbro 255 or similar), slightly larger (2.8 pink top) injectors and a rising rate fuel pressure regulator or FMU. Most aftermarket regulators run a 1:1 ratio with vacuum psi:fuel psi. However, I understand that I'll require a larger rate than that. Does anyone have any info on the sort of rising rate I should be looking at?
