Radium Engineering 2JZ-GE Fuel Rail for 1993-2002 Toyota Supra Models.

The Radium fuel rail for the 6-cylinder Toyota 2JZ-GE (Non-Turbo) engine is manufactured with a large 8AN ORB internal bore supporting all horsepower requirements. They are CNC machined from 6063 aluminum, black anodized, and laser etched for a high quality surface finish. For flexibility, the fuel rail features four 8AN ORB ports and is compatible with all fuel types including popular alcohol mixtures such as E85.

Late model 2JZ-GE vehicles use a returnless fuel system where the fuel pressure regulator (FPR) is integrated into the pump assembly. However, early model 2JZ-GE vehicles use a traditional fuel system with the FPR mounted directly to the fuel rail. For these setups, an aftermarket fuel pressure regulator will be required.

This fuel rail features four ports (both ends and two on the bottom) that are female tapped for 8AN ORB fittings. However, the front port is not useable unless the OEM engine harness is modified.

When using aftermarket injectors, it must be determined if the manifold is air-assist or not. Aftermarket injector requirements will be different based on that information

This is NOT compatible with the 2JZ-GTE (Turbo) engine.
