WRX owners are always looking for more power but quickly run out of fuel when they start chasing additional gains. 

Nostrum’s HPFP for the turbo FA20 is capable of flowing 40% more fuel than the factory fuel pump. The additional fuel flow allows you to dial in more boost earlier, resulting in a substantial increase in low end torque. Being that our pumps are ethanol compatible, you also have the added benefit of being able to run e85 or blended ethanol fuel. Ethanol is wonderful on turbo cars, as it has a higher octane rating and is less prone to knock than 91/93 pump gas, and you have the potential to make more power as a result. The HPFP can also be installed and driven on without a tune, but we recommend tuning to utilize the pump’s full potential. Our pumps are tunable on Cobb and ECUTek software. 

While the additional torque from the upgraded HPFP is a wonderful thing, most people are looking for more peak horsepower. Pairing our Stage 1 injectors, which flow 10% more than stock, with the upgraded HPFP creates the ultimate DI Fueling package for this platform. There’s no need to worry about secondary injection controllers, filling meth tanks or clogged meth injectors. These are the only aftermarket injectors for this platform that are 100% compatible with the stock ECU and tunable on Cobb or ECUTek. Injector Data and Tuning guides are available upon request.
