Radium Top Feed Fuel Rail Conversion Kit Toyota 1JZ-GTE Non VVT-i 20-0235

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).

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 (short spacers shown). 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.

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.
