Used NISMO Fuel Pressure Regulator FPR Type-A for RB26/RB25/SR20 “Adjustable fuel pressure regulator allows manipulation to the stock fuel pressure. For the limited 370cc stock S13 SR20DET injectors, one can squeeze out more fuel by raising the fuel pressure a bit from stock 36psi base pressure. The regulator still retains the factory 1:1 boost dependent ratio. Another benefit for changing the old regulator is that the old stock fuel pressure regulator can be sticking and creates problems such as hard cold/hot starts and excessive rich/lean conditions.” Nismo part number :22670-RR580 Will fit : Skyline - R33 GTS-t S2 - ECR33 Skyline - R33 GTS-t S1 - ECR33 Skyline - R32 GTR - BNR32 Skyline - R33 GTR - BCNR33 Skyline - R34 GTR - BNR34 Silvia - PS13 (Red Top) 180SX - RPS13 S2 (Black Head) 180SX - RPS13 S1 (Red Head) £60 + P&P or collect from Welwyn, AL6 or a DWYB
