NISMO ADJUSTABLE FUEL PRESSURE REGULATOR

NISMO ADJUSTABLE FUEL PRESSURE REGULATOR 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. * Will also fit RB25DET. - 196-588kPa - Diaphragm: 36.5mm - Operating temperature range: -30C - +120C Part Number: 22670-RR580
