Radium - Fuel Rail for Toyota 1JZ-GTE (VVT-i & Non-VVT-i)

The Radium Engineering High-Flow Fuel Rail for Toyota 1JZ-GTE brings modern fueling performance to the 2.5L inline-6 powerhouse. Available in dedicated geometries for both factory top-feed 1JZ-GTE VVT-i engines and side-feed to top-feed conversion configurations for early Non-VVT-i engines.

Key Performance Features:

• Engine-Specific Architecture: Engineered with tailored mounting provisions for both VVT-i (JZX100/JZX110) and early Non-VVT-i intake manifolds.
• Top Feed Conversion (Non-VVT-i): Seamlessly converts restrictive factory side-feed injectors to modern high-impedance top-feed injectors.
• Large Internal Damper Cavity: Ensures equal cylinder-to-cylinder fuel pressure distribution even under aggressive boost.
• 8AN ORB Ports: Threaded ends support massive fuel flows for 800+ HP builds with ethanol or pump gas.
• Ethanol Safe: Precision CNC machined from 6061 aluminum and black anodized for corrosion resistance.

Vehicle & Engine Compatibility:

• Toyota 1JZ-GTE VVT-i (JZX100, JZX110 Chaser / Mark II / Cresta / Crown)
• Toyota 1JZ-GTE Non-VVT-i (JZX81, JZX90, JZZ30 Soarer, JZA70 Supra)

Notice: Inlet and outlet ports are female ORB; male AN adapter fittings and hose ends are sold separately.
