DUAL PORT INJECTION KIT, SUBARU EJ
This kit is for Subaru EJ race engines that cannot be used on public roads. ECU tuning is required.
Dual port injection (2 per runner) make this kit a good match for high power engines using alternative fuels. They can also be used in a standard single injector configuration as well. HOWEVER, A STANDARD FUEL RAIL, SUCH AS 20-0567-02 OR 20-0577-02, MUST BE PURCHASED SEPARATELY.
FUEL RAIL HOUSINGS
These were designed in-house and utilize die-cast manufacturing to achieve shapes and features not possible with other manufacturing methods. The inner bores are perfectly smooth without machining marks.
The outer mounting bosses on the fuel rail housings are designed to provide additional clearance for larger turbo inlet pipes.
The eccentric threaded blocks (shown) make this kit compatible with a wide variety of Subaru EJ intake manifolds.
The fuel 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. The end ports are manufactured with large high flowing 10AN ORB end ports. 10AN ORB adapter fittings can be found HERE. The top auxiliary ports are threaded with 8AN ORB for ancillary accessories. 8AN ORB adapter fittings can be found HERE. 8AN ORB Fuel Pulse Dampers can be found HERE.
Press-fit spacers are included to thermally insulate heat transfer into the fuel rails. As shown, OEM top feed fuel rails are also compatible, including Radium Engineering 20-0567-02 OR 20-0577-02. HOWEVER, THESE ARE NOT INCLUDED AND MUST BE PURCHASED SEPARATELY. NOTE: Fuel rails that convert from side feed to top feed injectors are NOT compatible.
If additional fuel injectors (8 total) are required, the preinstalled 2AN ORB plugs can simply be unscrewed from the upper injector ports and can be used.
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.
