Radium Engineering Fuel Rails – Nissan R35 GT-R (VR38DETT)

Part Number: 20-0556-02

Compatibility

• Nissan R35 GT-R

• VR38DETT Engine

Product Overview

The Radium Engineering 20-0556-02 Fuel Rails are precision-engineered upgrade rails designed specifically for the Nissan R35 GT-R equipped with the VR38DETT engine. These are upgrade rails, meaning they retain OEM or OEM-equivalent fuel injectors.

If upgrading injectors, they must match OEM height and use identical upper and lower O-ring diameters and styles. Radium does not provide injector recommendations—consult your tuner for proper flow rate guidance and the injector manufacturer for correct dimensional fitment.

Premium Construction & E85 Compatibility

Each fuel rail is CNC machined from high-quality 6061 billet aluminum and anodized black for maximum durability and corrosion resistance. They are fully compatible with all popular fuel types, including E85, and feature a large internal bore to support high horsepower applications.

Port Configuration & Plumbing Flexibility

Each rail includes:

• Four 8AN ORB ports per rail

  • (2 end ports + 2 top ports)

• Eight total ports across both rails

This versatile configuration makes it easy to integrate:

• Fuel pressure transducers

• Fuel pulse dampers

• Pressure regulators

• Fuel pressure gauges

The system allows plumbing in parallel or series, depending on your fuel system design.

Note: The ports are tapped for 8AN ORB fittings. Proper fittings must be selected based on your specific setup. Always verify clearance for larger accessories using dimensional reference drawings.

Thermal Isolation Design

To reduce heat transfer from the intake manifold, the rails mount using:

• Thermal insulating spacers

• Thermal washers

This ensures maximum fuel temperature control and improved system efficiency. The OEM injector clips can be reused for a secure and factory-style installation.

What’s Included

• Anodized Billet Aluminum Fuel Rails (x2)

• Thermal Washers (x4)

• Thermal Spacers (x4)

• Stainless Steel Mounting Hardware

Important Notes

• This is an upgrade rail, not a top-feed conversion rail.

• OEM or OEM-equivalent injectors must be used.

• Radium Engineering does not make fuel injector recommendations.

• Consult your tuner for injector sizing and your injector manufacturer for dimensional compatibility.
