Radium Side Feed Conversion Fuel Rail Kit - Nissan Silvia/180SX S13 (SR20DET)

Radium Side Feed Conversion Fuel Rail Kit - Nissan Silvia/180SX S13 (SR20DET)

Application: Nissan S13 SR20DET (RWD intake manifold) – Silvia, 180SX, 200SX, 240SX
Part Type: Top feed conversion fuel rail
Part Number: 20-0558

The Radium Engineering Top Feed Conversion Fuel Rail for the Nissan SR20DET converts the factory side-feed injection to top-feed injectors. The CNC-machined rail has a 17.5mm (0.69in) internal bore and high-flow ports that accept a wide range of adapter fittings, with a black satin anodised finish safe for all gasoline and alcohol blends.

The rail bolts to the factory fuel rail mounting points. Billet aluminium injector seats – anodised and laser etched – press into the intake manifold to seal the top-feed injectors. Designed for the S13 SR20DET RWD intake manifold, it may also suit some aftermarket intake manifolds that use the OEM fuel rail.
