PORTS AND FITTINGS

The fuel rail end ports are tapped for 10AN ORB. The top ports are tapped for 8AN ORB.

10AN ORB Adapter Fittings can be found HERE.
8AN ORB Adapter Fittings can be found HERE.
8AN ORB Fuel Pulse Dampers 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 (20-0176 FPD-R shown below in top port).

Often there is minimal clearance near the turbocharger (20-0403 Swivel Banjo shown above). 


These Radium dual port injection (DPI) fuel rails were designed specifically for the Radium 20-0489 TGV Housing Kit and are NOT compatible with any other TGV housing on the market. Manufactured with large 10AN ORB end ports, the fuel rails can support all necessary engine power requirements. The top auxiliary ports are threaded with 8AN ORB for ancillary accessories. The rails are CNC machined from solid 6061 aluminum, black anodized, and laser engraved for a high quality surface finish. They are compatible with all fuel types including alcohol mixtures such as E85 and is a necessary modification for those using methanol on high powered engines.

Machined press-fit phenolic spacers (shown below) are included to insulate TGV housing heat transfer.


FUEL INJECTOR FITMENT

Each fuel rail has 4 injector ports that are machined to permit injectors with 14mm O-rings.

Primary Lower Fuel Injectors
Using the provided adapters, both OEM Subaru or 60mm Bosch EV14 style fuel injectors can be used. To reuse the OEM Subaru injectors, the provided top hat must be installed over the upper OEM injector O-ring as shown below. 

To use aftermarket 60mm Bosch EV14 injectors as shown below, 

 the provided injector seat must be installed over the lower injector O-ring.

Below are compatible aftermarket injectors for the lower primary ports.

Injector Dynamics ID1300x-60-14-14
Injector Dynamics ID1700x-60-14-14
Injector Dynamics ID2000-60-14-14

Secondary Upper Fuel Injectors
Only 34mm Bosch EV14 style fuel injectors can be used. Fortunately, many Subaru owners are currently already using Injector Dynamics XXXX.48.11.WRX fuel injectors. If the upper and lower billet caps are pulled off, the base injector is a 34mm Bosch EV14 which can be used. Below are the compatible secondary upper injectors.
