The Radium Fuel Rail for the non-turbo Toyota 2JZ-GE has a large 8AN ORB internal bore that supports all horsepower levels. It is CNC-machined from 6063 aluminium, black anodised and laser etched, and is compatible with all fuel types including E85.

The 11mm injector bores accept all factory 2JZ-GE injectors without modification, and injector seats are included for engines with Toyota air-assist manifolds. Four 8AN ORB female ports (both ends and two on the bottom) allow the rail to be plumbed to suit returnless or return-style systems.

Important Notes

• Not compatible with the 2JZ-GTE (turbo) engine
• Early-model engines with a rail-mounted regulator require an aftermarket fuel pressure regulator; late-model returnless systems have the regulator in the pump
• The front port cannot be used unless the OEM engine harness is modified
• Non-air-assist engines: aftermarket injectors must be OEM-equivalent (same height and O-ring dimensions)
• Air-assist manifolds: injectors must be 60mm long with an 11mm upper and 14mm lower O-ring; avoid 34mm-body injectors with top adapters as they can foul the connector
• Allow clearance around the ports for regulators, gauges and pulse dampers
• Installation instructions are available in the Instructions tab
