RB26DETT engines in the R32, R33, and R34 Skyline GT-R and Stagea 260 require robust fuel rails when running larger injectors or higher boost levels. The Radium Fuel Rail Engineering kit (20-0217) is a high-performance upgrade specifically designed for OEM intake manifolds, featuring a large 0.69" internal bore that supports substantial fuel flow for high-power applications. CNC machined from custom 6063 aluminum extrusion and finished with a black anodized surface, this rail provides excellent strength, corrosion resistance, and a professional engine bay appearance.
The upper injector bores are machined to 11mm ID (Denso) and include six custom Viton O-rings that allow the use of OEM RB26DETT JECS injectors with their 10.45mm ID. The rail is fully compatible with all fuel types, including E85 and alcohol mixtures. Front, rear, and center ports use 8AN ORB fittings for flexible high-flow fuel system builds, while the gauge port features 1/8" NPT threads for easy fuel pressure monitoring. The kit includes insulating phenolic spacers, washers, and stainless steel mounting bolts for a complete, ready-to-install solution.
At Terra Firma Automotive, we supply this genuine Radium Fuel Rail Engineering kit as a premium fuel system upgrade for RB26DETT owners seeking better flow and reliability. It transforms your fuel delivery into a strong, efficient system that supports your modified engine while maintaining a clean, high-end look. For enthusiasts serious about fuel system optimization and maximizing power potential, this Radium fuel rail is one of the most effective upgrades you can make to your Skyline.
