Radium Engineering 2JZ-GE 1993-2002 Fuel Rail

The Radium Engineering 2JZ-GE 1993-2002 Fuel Rail is now available for purchase. 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. 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. NOT compatible with the 2JZ-GTE (Turbo) engine.

The Radium Engineering fuel rail features 11mm injector bores making it compatible with ALL factory Toyota 2JZ-GE (Non Turbo) fuel injectors. This includes non VVT-i and VVT-i engines as well as air-assist and non air-assist injectors. No modifications are needed. If preparing to use aftermarket fuel injectors for engines that do NOT use Toyota air assist equipment, use your preferred injector manufacturer’s suggestion for OEM equivalent fuel injectors. Late model (and California-spec) 2JZ-GE engines use Toyota air-assist emissions equipment. These engines use a unique OEM fuel injector that is not replicated in the aftermarket. Air-assist intake manifolds require the Radium injector seats in order to use universal aftermarket fuel injectors, as shown in the picture below. When the provided Radium injector seats are installed into these air-assist intake manifolds, an aftermarket injector that is 60mm long with 11mm upper O-ring and 14mm lower O-ring must be used. The following universal injectors have been verified to be compatible, however there are others on the market that will work that are not listed here.
– Injector Dynamics ID1050x-60-11-14
– Injector Dynamics ID1300x-60-11-14
– Injector Dynamics ID1700x-60-11-14
– Injector Dynamics ID2000-60-11-14


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.
