Radium Fuel Rail | Toyota 2JZ-GE (20-0371)

The non-turbo 2JZ has been the sleeper platform for years, and its fuel rail finally caught up.

Boosted 2JZ-GE builds inherit the GTE's reputation with none of its rail options, since the GE's intake manifold architecture makes GTE rails incompatible. The Radium Engineering Fuel Rail for the Toyota 2JZ-GE is the purpose-built answer: CNC machined from 6063 aluminum, black anodized and laser etched, with a large 8AN ORB internal bore supporting all horsepower requirements and four 8AN ORB ports for plumbing, regulators, gauges, and dampers. The 11mm injector bores accept every factory 2JZ-GE injector, VVT-i or not, air-assist or not, and included Radium injector seats unlock aftermarket injectors on air-assist manifolds. Bolt-on, on the factory mounting bosses. E85 ready.

What You'll Feel

• Rail volume and flow that never becomes the ceiling as the single turbo goes on
• Four real ports replacing the factory rail's fixed plumbing: both ends plus two on the bottom
• Every factory injector dropping straight in, no modifications
• A documented aftermarket injector path even on air-assist manifolds, courtesy of the included seats
• Alcohol fuel confidence across E85 and beyond

Features

• CNC machined 6063 aluminum, black anodized and laser etched, with large 8AN ORB internal bore
• Four 8AN ORB female ports (both ends and two bottom); front port unusable unless the OEM engine harness is modified
• 11mm injector bores compatible with ALL factory 2JZ-GE injectors: VVT-i and non VVT-i, air-assist and non air-assist
• 6x Radium injector seats included for running aftermarket injectors in air-assist manifolds
• Reuses factory mounting bolts and plastic spacers for bolt-on installation
• Compatible with all fuel types including E85; NOT compatible with the 2JZ-GTE

The Details

Injector selection is where 2JZ-GE builds go sideways, and Radium documented the whole decision tree. Engines without Toyota's air-assist emissions equipment simply use OEM-equivalent aftermarket injectors per your injector supplier. Late model and California-spec engines with air-assist use a unique OEM injector the aftermarket never replicated, which is what the included Radium seats solve: install them in the air-assist manifold and run a 60mm aftermarket injector with 11mm upper and 14mm lower O-rings, with verified options including the Injector Dynamics ID1050/1300/1700/2600-XDS-60-11-14 family. One trap to avoid: injectors built as 34mm bodies with top adapters reaching 60mm can interfere with the connector at the manifold bores, so use true 48mm-height injectors with the appropriate configuration instead. Regulator planning splits by year too, since early GE cars carry a rail-mounted FPR and will need an aftermarket regulator with this rail, while late models are returnless with the FPR in the tank. Verify the factory mounting bolts and spacers are present before starting, and leave clearance around ports destined for larger accessories.
