Radium Engineering - Fuel Rails, Top Feed Conversion, Subaru EJ V3-6 - 92-01 Subaru Impreza
The "conversion" fuel rails convert the OEM side feed fuel injector setup to top feed allowing the use of high flow fuel injectors (not included). 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. Machined press-fit phenolic spacers are included to insulate intake manifold heat transfer. Two sets of spacers are included to accomodate popular 34mm or 48mm height universal fuel injectors from popular manufacturers.
DO NOT purchase "WRX Fitment" injectors. See more information about injector fitment below.
The 20-0335 kit included adapter brackets (shown above), which are required for certain applications.
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.
For the 20-0335-02 conversion fuel rails, adaptable mounting brackets are included that permits a wide range of Subaru vehicles to be used.
This 20-0335-02 kit is ONLY COMPATIBLE with 48mm height injectors. Below are some of the many fuel injectors that are a direct fit:
