• Nissan Skyline R34 GTS-T RB25DET NEO Engine

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.

This Radium Engineering fuel rail is CNC machined from extruded 6063 aluminum, black anodized, and laser etched for a high quality surface finish. Features a large 0.69' center bore that will easily support all stock and modified version of the RB25DET NEO.
The rails are compatible with all fuel types including popular alcohol mixtures such as E85.

This fuel rail is for the Nissan RB25DET NEO engine ONLY! This is commonly found in the R34 Skyline among others. For the Nissan RB25DET (non NEO) fuel rail, go HERE.
