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. However, they can also be used in a standard single injector configuration as well.
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 below) make this kit compatible with a wide variety of Subaru EJ intake manifolds.
FUEL RAILS
The fuel rails are CNC machined from solid 6061 aluminium, 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.
The top auxiliary ports are threaded with 8AN ORB for ancillary accessories.
Machined press-fit spacers (shown below) are included to insulate heat transfer into the fuel rails.
As shown, all top feed OEM fuel rails are also compatible, including Radium fuel rails found HERE. 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 the can be used, as shown below.
