Description

Subaru BRZ / Toyota 86 Fuel Upgrade Kit – Radium / Injector Dynamics ID1050-XDS

Upgrade the fuel delivery capability of your Subaru BRZ or Toyota 86 with a proven combination of Radium Engineering fuel rails and Injector Dynamics ID1050-XDS fuel injectors.

Designed for modified FA20-powered applications requiring increased fuel capacity, this package upgrades the port injection side of the factory fuel system with larger injectors and high-flow fuel rails. It is particularly well suited to forced induction builds, increased power levels and vehicles running ethanol-based fuels.

At the heart of the kit is a set of four Injector Dynamics ID1050-XDS fuel 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 performance for smooth idle, drivability and precise fuel control.

Corrosion-resistant internal components provide compatibility with all known fuels, making the ID1050-XDS suitable for conventional petrol, ethanol blends and E85.

The injectors are paired with Radium Engineering high-flow fuel rails. Manufactured from anodised aluminium, the rails feature a large 0.69-inch internal bore to provide ample fuel volume for high-performance applications. Each rail incorporates 8AN ORB end ports and a 6AN ORB centre port, providing flexibility when configuring fuel lines, regulators, pressure sensors and other fuel system components.

Together, the Radium fuel rails and ID1050-XDS injectors provide a comprehensive port fuel system upgrade for modified BRZ and Toyota 86 applications.

Radium Fuel Rail Kit

The Radium Engineering Port Injection Kit (PIK) installs between the intake manifold and the cylinder head and permits the use of port injectors to add additional fuel for high-horsepower modified K20C1 engines, commonly found in the FK8 Civic Type-R. This does NOT replace the OEM direct injection system. The kit includes the PIK adapter plate, custom fuel rail, fuel rail mounting hardware, and OEM Honda gaskets, as shown in the below picture. It is compatible with all fuel types including popular alcohol mixtures such as E85.

The fuel rail features a large 0.63" internal diameter bore. It is CNC machined from extruded 6063 aluminum and laser etched for a high quality surface finish. All 4 ports are machined with an 8AN ORB (3/4-16 female) threads. Note that the 2 top fuel rail ports will need to be plugged with 14-0150 unless the plastic OEM wiring harness carrier is modified (see in pictures).

Machined phenolic mounting spacers and washers are included to completely isolate the fuel rail from heat created by the cylinder head and transferred through the mounting bolts. The injectors are at a specific angle to ensure proper spray into the intake ports, as shown above.

This kit is designed for specific top feed fuel injectors with upper and lower O-ring spacing, as depicted below. The upper and lower injector O-rings must be 14mm diameter. The included fuel rail mounting brackets permit 2 different height fuel injectors to be used, as shown above.

Injectors are not included, consult the fitment guide below before purchasing injectors.
