OEM TOYOTA INJECTORS ON 2JZ-GE ENGINESThe Radium Engineering fuel rail features an 11mm injector bore 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, read below.
AFTERMARKET INJECTORS ON 2JZ-GE ENGINES (WITHOUT AIR-ASSIST)
For engines that do NOT use Toyota air assist equipment, use your preferred injector manufacturer's suggestion for OEM equivalent fuel injectors. DO NOT USE THE INJECTORS LISTED BELOW WHICH ARE FOR AIR-ASSIST ENGINES ONLY.
AFTERMARKET INJECTORS ON 2JZ-GE ENGINES WITH AIR-ASSIST 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.
