NOTE: Fuel Injectors are NOT included and must be purchased elsewhere. Both ports use positive o-ring seals instead of tapered pipe threads which commonly damage aluminum threads and lead to fuel leaks. Both ends of the rail are tapped to a common 3/4-16 (-8AN) female thread. Use the shorter spacers and mounting bolts to accommodate this size injector:īelow are some of the many fuel injectors that are a direct fitment with this Radium fuel rail kit using the short spacers: This all new design was specifically designed to clear the intercooler mounting boss. Use the tall spacers and longer mounting bolts to accommodate this size injector:īelow are some of the many fuel injectors that are a direct fitment with this Radium fuel rail kit using the tall spacers: The Radium fuel rail is the first and only on the market to support an (optional) fuel pulsation damper. The Radium Engineering fuel rail plumbing kit are designed to compliment Radium Engineering Subaru EJ fuel rail installations and allows easy hookup to the.
It is compatible with all fuel types including popular alcohol mixtures such as E85. The thermally insulating spacers offer excellent resistance to heat transfer. Price 149.95 Radium Fuel Rail Kits are CNC machined from solid 6061 aluminum and black dipped anodized for a high quality surface finish. The kit includes 2 sets of spacers to suit multiple height injectors. These injector seats require fuel injectors with a 14mm lower O-ring (common size). The green injector seats press into the intake manifold and provide a sealed base for the top feed fuel inejctors to sit on. The rail is extruded and CNC machined from solid 6063 aluminum and black anodized for a high quality surface finish. The fuel rail has four 8AN ORB ports that can be used for fuel inlet, outlet or for plumbing option accessories. Designed for 14mm O-ring injectors CNC machined Aluminum Laser etched and anodized Stainless steel hardware Heat insulating mounts.US237. 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 is commonly found in the R33 Skyline among others. This fuel rail is for the Nissan RB25DET (non NEO) engine ONLY.
Like the OEM fuel rails, the injector bores are 14mm ID so factory injectors are permitted. They are CNC machined from extruded 6063 aluminum, media blasted, black anodised, and laser etched for a high quality surface finish. Manufactured with a large 0.69″ internal bore, the fuel rail can support all necessary engine power requirements. For these reasons, top motorsports competitors and enthusiasts worldwide rely on Radium Engineering products. Extensive testing and evaluation ensures the performance of Radium products exceed consumer expectations. All Radium products are carefully planned with thorough R&D and designed in-house using the latest computer simulation and modeling techniques.
