Description   Nostrum High Performance High Pressure Fuel Pump 15-21 Subaru WRX The Nostrum Subaru FA20 High Pressure Fuel Pump ( HPFP ) provides a 40% increase in fuel capacity vs the stock pump. It's Ethanol Compatible up to 100% Ethanol, capable of 600 WHP on E85. Please be aware a profession tune is required and suggested use with MoTec. Running this will require you also to upgrade your vehicles in tank fuel pump ( low pressure ). Fuel System limitations due to the low pressure fuel pump frequently seen at high RPM's and high power levels. The HPFP needs a constant supply of fuel pressure ( around 4 bar ) at its inlet in order to avoid cavitation. If the in-tank fuel pump cannot supply sufficient fuel pressure /- flow, it will starve the HPFP at higher RPM's. Functionally your vehicle does not require calibration changes to operate with the Nostrum HPFP. With the Nostrum HPFP, it is possible to request higher fuel rail pressures at higher RPM's: however, Nostrum does not recommend requesting more than 170 bar of pressure. Designed, developed, validated, and tested in the USA.
