RADIUM ENGINEERING TOP FEED FUEL RAIL CONVERSION KIT
FUEL INJECTORS
Do NOT purchase "WRX top feed" injectors.
This application uses universal injectors. Injectors must have 14mm O-rings top and bottom and must match the 34mm height dimensions shown below.
Many injector manufacturers will have applications with these dimensions. Here are a few examples of applicable injector part number from Injector Dynamics:
- Injector Dynamics ID1050-XDS 1050.34.14.14
- Injector Dynamics ID1300-XDS 1300.34.14.14
- Injector Dynamics ID1700-XDS 1700.34.14.14
- Injector Dynamics ID2600-XDS 2600.34.14.14
OVERVIEW
Each fuel rail features three 8AN ORB threaded ports (6 total). Press-fit spacers are included to thermally insulate intake manifold heat transfer. Conversion fuel rails convert the OEM side feed fuel injector setup to top feed allowing the use of high flow fuel injectors. The fuel rail injector bores are 14mm ID. 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 engraved for a high quality surface finish. The fuel rails are compatible with all fuel types including popular alcohol mixtures such as E85. The four billet injector seats are anodized and laser etched and provide a sealed receptacle for top feed fuel injectors. The seats are designed for injectors with 14mm lower O-rings.
Fuel Injectors are NOT included and must be purchased elsewhere.
