Consistent fuel delivery becomes critical once injector size and fuel demand increase on an RB26DETT. The Tomei Fuel Rail JECS Style (part number TB511A-NS05A) is a billet aluminum upgrade designed specifically for the Nissan RB26DETT in the Skyline R32, R33, and R34 GT-R, providing greater internal capacity and more stable fuel distribution than the factory rail.
Machined from billet aluminum and finished in Tomei’s distinctive blue anodizing, the rail features a larger internal volume that supports even fuel supply when oversized injectors are fitted. The JECS-style injector ports use a 10.45 mm hole size, making the rail compatible with corresponding top-feed injectors. Improved heat dissipation characteristics help reduce the risk of fuel percolation under high under-hood temperatures, while the rigid billet construction contributes to more consistent pressure delivery. AN fittings are included for straightforward integration into aftermarket fuel systems.
This fuel rail is a practical upgrade for builders moving beyond stock injectors and seeking a clean, high-capacity solution that also improves under-hood appearance. At Terra Firma Automotive, we supply this genuine Tomei JECS-style Fuel Rail as a proven component for RB26DETT performance builds. Whether the engine is being prepared for higher horsepower or simply needs a more capable fuel distribution system, this rail delivers the capacity and reliability expected from Tomei. Choose Terra Firma Automotive for authentic Japanese fuel system components that support serious Skyline GT-R builds.
