Radium Top Feed Conversion Fuel Rail - Nissan Skyline R33 (RB25DET)

Application: Nissan RB25DET (non-NEO), e.g. R33 Skyline GTS-T
Part Type: Top feed conversion fuel rail
Part Number: 20-0277


The Radium RB25DET fuel rail converts the factory side-feed injector arrangement to top-feed injectors, opening up a wide range of aftermarket injector options. Its large 0.69" internal bore supports a wide range of engine power levels, and the rail is compatible with all fuel types including E85.

The rail is extruded and CNC machined from solid 6063 aluminium and black anodised, with four 8AN ORB ports for inlet, outlet or accessory plumbing. Two sets of thermally insulating spacers are included to suit either 48mm or 34mm tall injectors.
