Description
INCLUDED:
20-0215 Toyota 2JZ-GTE Fuel Rail:
-Black Anodized Laser Etched Aluminum Fuel Rail
-Black Anodized Aluminum Mounting Feet, Tall and Short
-Stainless Steel Mounting Feet Bolts (x4)
-20-0216-06 Toyota Injector Seat Kit, 6 Cylinder
The extruded rail features a large 0.69″ internal diameter bore to suit even the most fuel hungry engines. They are CNC machined from a custom 6063 aluminum, media blasted, black anodized, and laser etched for a high quality surface finish. This kit is compatible with all fuel types including popular alcohol mixtures such as E85. All 3 ports (2 end ports and 1 center port) are tapped with 3/4″-16 female threads (-8AN ORB), as shown below.
The Radium fuel rail converts the OEM side feed fuel injector setup to top feed, allowing the use of high flow fuel injectors (NOT INCLUDED). The kit includes 2 different sets of mounting feet allowing various height fuel injectors to be used (tall spacers shown below).
The anodized aluminum mounting feet secure the fuel rail to the intake manifold reusing the OEM Toyota thermal insulating spacers.
The fuel injector bores and the included press-fit injector seats are designed for 14mm injector O-rings. These seats include O-rings to prevent boost pressure leaks. They are CNC machined billet aluminum, anodized, and laser etched. Below are some of the many fuel injectors that are a direct fitment with this Radium fuel rail kit.
Here is a list of some of the more popular compatible injectors:

To reuse the OEM fuel pressure regulator, select the 20-0301 (shown below). If securing to the front port, modification to the Traction Control TPS sensor is required when using the tall spacers. Check for firewall clearance if mounting on the rear port.
Fuel Pulse Damper(s)
Do I need pulse dampers? The opening and closing of the injectors creates pressure pulses in the fuel rail, which can lead to unstable fuel pressure. In order to achieve a safe and consistent rail pressure, a fuel pulse damper should be used (especially with high flow injectors). The internal diaphragm will absorb oscillation pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help an erratic surging idle.
