Radium Engineering Top Feed Fuel Rail – Nissan SR20DET (S14 / S15)

This Radium Engineering fuel rail is designed specifically for the Nissan SR20DET S14/S15 OEM intake manifold. It converts the factory side feed injector setup to top feed, enabling the use of high flow 14mm injectors (not included).

CNC machined from solid 6061 aluminium, the rail features a 17.5mm (0.69") internal bore, supporting high horsepower applications and compatibility with all fuel types including ethanol and E85.

Included thermal insulating spacers and washers isolate the fuel rail from engine heat. The billet aluminium injector seats are green anodised and laser etched, designed to accept 14mm lower O-ring injectors with 34mm body length.

The kit also includes a CNC-machined IACV spacer to provide clearance for the fuel rail. An anodised barb adapter, rubber hose, and gasket allow proper rerouting of the bypass line.
