Subaru EJ Fuel Rail & Injector Upgrade Kit – Radium / Injector Dynamics ID1050-XDS

Upgrade your Subaru EJ fuel system with a proven combination of Radium Engineering fuel rails and Injector Dynamics ID1050-XDS fuel injectors. Designed for modified and higher-output applications, this package provides increased injector capacity along with high-flow fuel rails to support increased fuel demand.

At the heart of the kit is a set of four Injector Dynamics ID1050-XDS injectors. Developed in partnership with Bosch Motorsport, the ID1050-XDS delivers a nominal flow rate of 1065cc/min at 3.0 bar while retaining excellent low-flow control for consistent idle and drivability. Corrosion-resistant internals provide compatibility with all known fuels, making them suitable for both conventional petrol and ethanol-based fuel systems.

The injectors are paired with Radium Engineering's top-feed upgrade fuel rails. CNC machined from 6061 aluminium, black anodised and laser etched, the rails feature a large internal bore designed to provide ample fuel volume for high-performance applications. Each rail incorporates multiple 8AN ORB ports, providing flexibility when configuring fuel lines, regulators, pressure sensors and other fuel system components.

Together, the Radium rails and ID1050-XDS injectors provide a solid foundation for upgrading the fuel system on modified Subaru EJ-powered vehicles, particularly where increased boost, turbocharger upgrades or ethanol fuels require greater fuel delivery capacity.


Injector Dynamics 1050-XDS Injectors

The ID1050x is the evolution of the ID1000, and the latest addition to the X-Series. It is the most recent offering from the partnership of Injector Dynamics and Bosch Motorsport, and is the result of lessons learned during development of the ID1300x, and ID1700x. Like the ID1300x and ID1700x, the ID1050x is not a modified production component. It is a built to spec motorsport injector, offering optimization of critical operating parameters important to you, the motorsport tuner. Compared to the original ID1000, the ID1050x offers numerous improvements, and is sure to become the new reference.


Radium Top Feed Upgrade Fuel Rails w/Bottom FPD Port

Manufactured with a large internal bore, the fuel rails can support all necessary engine power requirements. They are CNC machined from solid 6061 aluminum, black anodized, and laser etched for a high quality surface finish.

These fuel rails are designed specifically for OEM or equivalent fitment injectors. For injector height flexibility and thermal insulation, 2 sets of machined phenolic spacers are included. All injectors must use 11mm diameter upper O-rings just like the OEM Subaru injectors. Reference instruction manual for more information.

The fuel rails are compatible with all fuel types including popular alcohol mixtures such as E85.

These fuel rails have the same mounting and injector spacing as the Radium 20-0479-02 Top Feed Rails. However, these fuel rails feature a 8AN ORB port machined in the underside center of each fuel rail.

The fuel rail ports are tapped for 8AN ORB but fittings are not included.

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.

 Note: Fuel Pulse Dampener (FPD) Not Included
