Default 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

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

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.

Enginetuner said it was unsuitable for a hatch

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.

I'm going to guess it was because they ran out of time due to other jobs, and the fuel lab wasn't plug and play like the Perrin that they recommended. Anyway, the Fuel lab is up for sale as I bought a Perrin.
