Radium Engineering Fuel Rail Top Feed Conversion, Nissan RB25DET Non Neo
This Radium Engineering fuel rail kit is a direct bolt-on with the RB25DET (non NEO) engines originally found in the R33 Nissan Skyline GTS-T. Manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements. The Radium fuel rail converts the OEM side feed fuel injector setup to top feed allowing the use of high flow 14mm O-ring fuel injectors (not included). This kit is compatible with E85.
The fuel rail has four 8AN ORB ports that can be used for fuel inlet, outlet or for plumbing option accessories. All unused ports must be plugged.
The rail is extruded and CNC machined from solid 6063 aluminum and black anodized for a high quality surface finish.
