Malpassi Power Boost Valve

Adjustable Fuel Pressure Regulator

Everyone knows how essential it is to get fuelling right on tuned cars! So if you want to get the best from your tuned RB25DE Neo engine you could use one of these quality adjustable fuel pressure regulators.  

  • R34 GT Skyline RB25DE Non Turbo
  • accurately adjust the base pressure behind your injectors
  • essential for setting up tuned engines
  • referenced to manifold pressure
  • mounting plate cast into base of regulator for ease of fitment
  • locknut, and protective domed nut to help prevent alteration of pressure once set
  • adjustment is by 4mm allen key, which is included in the fitting kit
  • take off for a fuel pressure gauge (gauge is not supplied)
  • comes with fitting kit- silicon vacuum hose, 4 x jubilee clips, 2 x 8mm fuel spigot, & adjusting allen key.

Unlike some cheaper regulators these are properly referenced to the manifold pressure. As the manifold pressure changes (vacuum on cruise, higher pressure under boost) the injectors are 'seeing' different pressures, but the ECU fuel maps are configured for a steady state. The vacuum take off means our fuel pressure regulators constantly adjust the fuel pressure to suit the ambient pressure inside the manifold- keeping your chosen fuel pressure secure and accurate.

For those trying to get the most out of their stock injectors these adjustable fuel pressure regulators mean you can increase the base pressure behind the injectors. This has the same effect as fitting slightly bigger injectors as more fuel is dispensed for each opening of the injector.

Please note- for best results this regulator should be set up professionally with the aid of a rolling road and/or wide band lambda.
