[PN: 20-0359] Radium Fuel Rail, Top Feed Conversion, Nissan SR20DET (S14/S15)

PORTS AND FITTINGS

The fuel rail features three 8AN ORB ports.

8AN ORB Adapter Fittings can be found HERE.

8AN ORB Direct Mount Regulators can be found HERE.

8AN ORB Fuel Pulse Dampers can be found HERE.

Fuel Pressure Gauge Adapters can be found HERE.

Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.

This Nissan Silvia fuel rail is specifically designed for the SR20DET S14/S15 OEM intake manifold. For the SR20DET S13 fuel rail kit, go HERE. 

Manufactured with a 0.69" large 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 insulating spacers mount the rail to the OEM intake manifold bosses thermal isolation. The Radium fuel rail converts the OEM side feed fuel injector setup to top feed, allowing the use of high flow fuel injectors (not included). The fuel injector bores are 14mm ID. The kit is designed for specific upper and lower O-ring spacing, as depicted.

Below are some of the many fuel injectors that are a direct fitment:

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

To resist oxidation corrosion, 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. The OEM 2-bolt IACV bypass hard line is replaced by a billet aluminum IACV spacer kit to gain clearance for the top feed fuel rail. An anodized aluminum barb adapter and rubber hose is supplied to reroute the charge pipe hose externally to the manifold. One gasket is included for the IACV spacer. To replace the original IACV gasket, go HERE.
