Specifications
This fuel rail is for the Nissan RB25DET (non NEO) engine ONLY. This is commonly found in the R33 Skyline among others. For the RB25DET NEO fuel rail, go HERE Manufactured with a large 0.69" internal bore, the fuel rail can support all any engine power requirements. The Radium fuel rail converts the OEM side feed fuel injector setup to top feed injectors, allowing the use of a wide variety of aftermarket fuel injectors available on the market. 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. The green injector seats press into the intake manifold and provide a sealed base for the top feed fuel inejctors to sit on. These injector seats require fuel injectors with a 14mm lower O-ring (common size). Read more Fuel Injector Compatibility The kit includes 2 sets of spacers to suit multiple height injectors. The thermally insulating spacers offer excellent resistance to heat transfer. Use the tall spacers and longer mounting bolts to accommodate this size injector: Below are some of the many fuel injectors that are a direct fitment with this Radium fuel rail kit using the tall spacers: Injector Dynamics ID725-48-14-14 Injector Dynamics ID850-48-14-14 Injector Dynamics ID1000-48-14-14 Injector Dynamics ID1050x-48-14-14 Injector Dynamics ID1300-48-14-14 Injector Dynamics ID1700-48-14-14 Injector Dynamics ID2000-48-14-14 Evolved Injection EI550-48-14-14 Evolved Injection EI650-48-14-14 Evolved Injection EI850-48-14-14 Evolved Injection EI1000-48-14-14 Evolved Injection EI1200-48-14-14 Evolved Injection EI1300-48-14-14 Evolved Injection EI2200-48-14-14 Deatschwerks 17U-00-0050-6 Deatschwerks 17U-00-0060-6 Deatschwerks 17U-00-0072-6 Deatschwerks 17U-00-0095-6 Deatschwerks 16S-12-2200-6 Use the shorter spacers and mounting bolts to accommodate this size injector: Below are some of the many fuel injectors that are a direct fitment with this Radium fuel rail kit using the short spacers: Injector Dynamics ID850-34-14-14 Injector Dynamics ID1050x-34-14-14 Injector Dynamics ID1300-34-14-14 Injector Dynamics ID1700-34-14-14 Injector Dynamics ID2000-34-14-14 Evolved Injection DPI550-38-14-14 Evolved Injection DPI650-38-14-14 Evolved Injection DPI850-38-14-14 Evolved Injection DPI1000-38-14-14 Evolved Injection DPI1200-38-14-14 Evolved Injection DPI1300-38-14-14 Evolved Injection DPI2200-38-14-14 RC Engineering SM2-0310 RC Engineering SM2-0370 RC Engineering SM2-0450 Deatschwerks 16U-00-0042-6 Deatschwerks 16U-00-0050-6 Deatschwerks 16U-00-0065-6 Deatschwerks 16U-00-0090-6 Deatschwerks 16M-00-1500-6 Deatschwerks 16M-00-2200-6 NOTE: Fuel Injectors are NOT included and must be purchased elsewhere.
