Fuel Pressure Reg?
So I’m slowly girding parts to take my standard blob wrx up a notch with only the injectors and a SC36 outstanding. Is it worth upgrading the FPR to a aftermarket such as fuel labs if so any suggestions? |
I've got a fuel lab fpr available, universal,as it wasn't suitable for my hatch. It's a good mod if you are upping bhp, and some mappers recommend them before heading into the 360 zone

If it's unsuitable, its probably for an N/A car, not turbocharged; who said it was unsuitable? To the OP, you'd be wise to replace the fuel pump as a matter of course if it's the original or if you're unsure how old it is, as well as replacing the regulator. |

All Fuelab regs are universal. All reputable retailers for the Subaru market supply them with fittings.

Got after market FPR and a FP Gauge on mine.
Being a defi, it's linked to the boost gauge to show DIFFERENTIAL FUEL PRESSURE. Saved my engine once already. |
