Radium Engineering Top Feed Conversion Fuel Rails - Subaru WRX / STI (EJ20 V3-V6)
Radium Engineering's 20-0569-02 fuel rails convert early Subaru EJ20 turbo engines with OEM side-feed intake manifolds to universal top-feed injectors. They are designed for the Version 3–6 JDM models and open up far more injector choices while simplifying the plumbing.
Each rail has three 8AN ORB ports (six in total), press-fit spacers thermally insulate the rails from intake manifold heat, and adaptable mounting brackets are included to suit a wide range of Subaru vehicles. The rails are compatible with all fuel types including E85.
Note: Do not use "WRX fitment" injectors. Compatible injectors must have a 48mm body length with 14mm upper and lower O-rings – verified options are Injector Dynamics ID1050, ID1300, ID1700 and ID2600 (XDS-48-14-14). Injectors and fittings are not included. Match your intake manifold to the correct Radium rail part number before ordering. Installation by a professional is recommended.
