Radium Engineering Toyota 2JZ-GTE Top Feed Fuel Rail Conversion

TheRadium Engineering Toyota 2JZ-GTE Top Feed Fuel Rail Conversion are now available for purchase. Compatible with all Toyota 2JZ-GTE engines (VVTi and non-VVTi). Manufactured with a large 0.69″ internal bore, the fuel rail can support all necessary engine power requirements. 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.

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:

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.

To reuse the factory fuel feed line, select 14-0285 8AN ORB to M12x1.25mm Female Fitting. This can secure to the rear port and reuse the OEM fuel feed banjo bolt.
