This Nissan Silvia/180SX/200SX fuel rail kit is designed specifically for SR20DET S13 style intake manifolds. This S13 SR20DET fuel rail will work on aftermarket intake manifolds that are compatible with the OEM side feed fuel rail. Manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements. The rail is CNC machined from solid 6061 aluminum and black anodized for a high quality surface finish. The included hardware mounts the fuel rail to the OEM intake manifold bosses.

The Radium fuel rail converts the OEM side feed fuel injector setup to top feed allowing the use of high flow 14mm O-ring short (34mm) fuel injectors. Fuel injectors are not included and not sold by Radium Engineering. Reference the diagram below to ensure you are using compatible fuel injectors.

Below are some of the many fuel injectors that are a direct fitment with this Radium fuel rail kit using the short spacers:

  • Injector Dynamics ID1050-34-14-14
  • Injector Dynamics ID1300-34-14-14
  • Injector Dynamics ID1700-34-14-14
  • Injector Dynamics ID2600-34-14-14

The lower billet aluminum injector seats are anodized and laser etched. They are O-ring sealed and designed for 14mm top feed injectors.  This kit is compatible with all fuel types including popular alcohol mixtures such as E85.

All parts listed below are included for a trouble and leak-free installation.

  • Black Anodized Aluminum Fuel Rail
  • Black Anodized Aluminum 30mm Injector Seats (20-0160-04)
  • 3x Stainless Steel Mounting Brackets
