I want to let you guys know that there is now a new Fuel Pressure Regulator that is a direct bolt-on to the fuel rail for the 2JZ and 4AG. It has the following features:
*Direct Bolt-On to the factory of aftermarket fuel rail with no additional fuel connections
*Piston-based actuator without a diaphragm to fail
*Re-buildable with new seals
*Elimination of diaphragm reduces noise and pulsation in the fuel rail
*Will support over 1000+ HP
*Interchangeable bypass orifices to accomodate upgraded higher flow fuel pumps
*Adjustable static fuel pressure via a turn screw
*Dedicated Port for 1:1 ratio per pound of boost
*Boost-only chamber for a total of 12:1 ratio only if needed.
*Infinitely adjustable rising rate ratio from 1:1 to 12:1
*Retain fuel pressure in rail, so that you don't have to prime the fuel pump on the next startup
*Sealed chamber for direct injection of Nitrous to raise fuel pressure. Partioned from vacuum and fuel.
