Radium Engineering Fuel Rail, Top Feed Conversion for Nissan SR20DET S14/S15

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.

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
