Application: Nissan KA24DE (twin cam) – 240SX, Bluebird, R'nessa, Presage, Bassara
Part Type: Top feed conversion fuel rail
Part Number: 20-0957

The Radium Engineering 20-0957 fuel rail is a direct bolt-on for all twin cam Nissan KA24DE engines. It converts the OEM side-feed injector setup to top feed, allowing the use of high-flow 14mm O-ring fuel injectors, and its large 17.5mm (0.69in) internal bore supports all necessary engine power requirements.

The rail is CNC machined from solid 6061 aluminium and black anodised, making it compatible with all fuel types including E85. It has three 8AN ORB ports (both ends and the bottom) and one 1/8in NPT port on top, and comes with thermal insulating spacers, washers and injector seats.
