Compatible with all Toyota 2JZ-GTE engines (VVTi and non-VVTi)

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 ports are tapped with 3/4"-16 female threads (-8AN ORB). 

As shown below, if the kit was purchased after June 5, 2017 the fuel rail features 2 bottom ports (4 ports in total).

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 (P/N: 90561-08009).

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.

Use the tall spacers to accomodate this size injector:

Shown below is the fuel rail installed on a 2JZ with VVTi.


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.
