PORTS AND FITTINGS

The fuel rail ports are tapped for 8AN ORB.

8AN ORB Adapter Fittings can be found HERE.
8AN ORB Direct Mount Regulators can be found HERE.
8AN ORB Fuel Pulse Dampers can be found HERE.
Fuel Pressure Gauge Adapters can be found HERE.

Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.

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:

Below are some of the many fuel injectors that are a direct fitment with this Radium fuel rail kit using the tall spacers:
Injector Dynamics ID1050x-48-14-14
Injector Dynamics ID1300x-48-14-14
Injector Dynamics ID1700x-48-14-14
Injector Dynamics ID2000-48-14-14 

To permit increased throttle body clearance, we recommend using the short spacers in conjunction with the injector sizing described below:

Below are some of the many fuel injectors that are a direct fitment with this Radium fuel rail kit using the short spacers:

Injector Dynamics ID1050x-34-14-14
Injector Dynamics ID1300-34-14-14
Injector Dynamics ID1700-34-14-14
Injector Dynamics ID2000-34-14-14 

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.
