Nissan RB25DET Fuel Rail Kit with Bosch 1200cc Injectors & Turbosmart FPR6

Nissan RB25DET Fuel Rail Kit with Bosch 1200cc Injectors & Turbosmart FPR6

Upgrade your Nissan RB25DET fuel system with this high-performance Fuel Rail Kit, featuring a Raceworks Fuel Rail, six modified Bosch 1200cc Injectors and a Turbosmart FPR6 Black Fuel Pressure Regulator. Designed for Nissan Skyline R33 ECR33 RB25DET engines, this package combines quality components from trusted performance brands to deliver reliable fuel flow, precise fuel pressure control and consistent fuel delivery.

The Raceworks Fuel Rail is precision machined from high-grade 6061-T6 aluminium and finished in black for durability and a clean engine bay appearance. Featuring AN-8 O-ring ports at each end and an AN-6 centre port, the fuel rail is designed to accommodate 3/4-length or full-length injectors with 14mm top O-rings. Supplied with machined fittings and lower manifold adapters, it provides a convenient upgrade for high-performance fuel systems and top-feed injector conversions.

The Bosch 1200cc Fuel Injectors are modified for high-flow performance, delivering 1200cc/min at 3 bar and 1400cc/min at 4 bar. Featuring high impedance (12 Ohms), Denso connectors and a narrow cone spray pattern, these injectors are ethanol and methanol safe, with a flow variance of just ±1.5% across the set of six.

The Turbosmart FPR6 Black Fuel Pressure Regulator delivers precise fuel pressure control with a true 1:1 pressure ratio and superior flow and bypass capacity. Featuring a stainless steel valve seat and Milspec diaphragm, the FPR6 is compatible with a wide range of fuels, including race fuels and aggressive leaded fuels, and supports fuel systems up to 1200HP.
