Nissan S15 Fuel Rail Kit with Bosch 1200cc Injectors & Turbosmart FPR6

Upgrade your Nissan S14, S15 and SR20 fuel system with this high-performance Fuel Rail Kit, featuring a Raceworks Fuel Rail, four modified Bosch 1200cc Injectors and a Turbosmart FPR6 Black Fuel Pressure Regulator. Designed for Nissan Silvia and 200SX S14 S15 SR20 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 O-ring centre port, the fuel rail is designed to accommodate short injectors with 14mm top O-rings. Supplied with lower manifold adapters and an IACV spacer, 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 specified flow variance of just ±1.5% across a 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.
