FUEL INJECTORS
There are two type of fuel rails made by Radium: upgrade rails and top feed conversion rails. Upgrade rails only upgrade the rail and the OEM fuel injectors can be reused. If an upgrade to the injectors is desired, they must be equivalent to the OEM injector, meaning they must be the same height and the upper & lower O-rings must match the OEM diameters and styles. Top feed conversion rails are used to convert a vehicle that has side feed (or sometimes air-assist) injectors over to a top feed injector.
This fuel rail is an upgrade rail. OEM or OEM equivalent injectors must be used.
Radium does not make fuel injector recommendations.
- Consult your tuner for injector brand or flow rate recommendations.
- Consult the injector manufacturer for a part number that has the correct dimensions.
OVERVIEW
20-0556-02 Fuel Rails Nissan R35 GT-R
These Radium Engineering fuel rails are compatible with the VR38DETT engine found in the Nissan R35 GT-R. They are machined from 6061 aluminum and anodized black for compatibility with all popular fuel types including E85. Manufactured with a large internal bore, the fuel rail can support all necessary engine power requirements. Each rail has four 8AN ORB ports (2 end ports and 2 top ports for a total of 8 ports).
The fuel rails mount with insulating spacers and washers for 100% fuel insulation from the hot intake manifold. The unique lower intake manifold mounting points permit shorter less restrictive rails. Additionally, the OEM injector clips can be reused, as shown below.
With 4 ports on each rail (8 total), it is easy to add fuel system accessories such as a pressure transducer, fuel pulse dampers, etc. There is also opportunity to plumb the fuel rails in parallel or series.
The fuel rail ports are tapped for 8AN ORB fittings.
- 8AN ORB Adapter Fittings 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.
