Radium Fuel Rail, Top Feed Conversion, Nissan SR20DET (S14/S15)

Application: Nissan Silvia / 200SX S14 and S15 (SR20DET)
Part Type: Top feed conversion fuel rail kit
Part Number: 20-0359


The Radium SR20DET fuel rail converts the S14 and S15 factory side-feed injector arrangement to top-feed, allowing high-flow aftermarket injectors to be used. It is CNC machined from solid 6061 aluminium and black anodised, with a 0.69" internal bore and three 8AN ORB ports.

The rail mounts to the OEM intake manifold bosses on thermal insulating spacers, with anodised and laser-etched billet injector seats. The OEM two-bolt IACV bypass hard line is replaced by the included IACV spacer kit, and a barb adapter with rubber hose reroutes the charge pipe connection externally. Compatible with all fuel types including E85.


Key Features

  • Top Feed Conversion: Converts OEM side-feed injectors to top-feed
  • Large Bore: 0.69" internal bore
  • 8AN ORB Ports: Three ports for flexible plumbing
  • Thermal Isolation: Insulating spacers and washers
  • IACV Solution: IACV spacer, gasket and barb adapter replace the OEM bypass hard line
  • Fuel Compatibility: Compatible with all fuel types including E85

What's Included

  • Black anodised aluminium fuel rail
  • Thermal insulating spacers and washers
  • Green anodised aluminium 25mm injector seats
  • Black anodised aluminium IACV spacer
  • IACV gasket for SR20DET S14/S15
  • Black anodised aluminium IACV barb adapter
  • Rubber hose and OEM clamp for the IACV
  • Stainless steel M8x1.25 mounting bolts
  • Stainless steel M6x1 mounting bolts

Optional Parts

  • Radium IACV Gasket - Nissan S14/15 (SR20DET) (18-0014) - replacement IACV gasket

Important Notes

  • Fuel injectors are not included
  • Injectors must be 34mm tall with 14mm upper and lower O-rings - the short height avoids bonnet clearance issues (e.g. Injector Dynamics ID1050-XDS, ID1300-XDS, ID1700-XDS, ID2600-XDS in 34mm)
  • The S13 SR20DET uses a different Radium kit
  • Fittings must be selected for your application - allow clearance around the ports for regulators, gauges and pulse dampers
  • Installation instructions are available in the Instructions tab
