RADIUM ENGINEERING Nissan S14/S15 SR20DET Fuel Rail Kit

Radium Engineering 20-0359 - Top Feed Conversion SR20DET (S14/S15) fuel rail.

A lightweight plug-and-play fuel rail that converts the factory side feed injector system to top feed on SR20DET engines from S14 and S15 models. Provides high fuel flow and full compatibility with E85 blends.

Key features

• CNC body made of 6061 aluminum, black anodized - low weight, corrosion resistance and aesthetic laser marking.
• Large 0.69″ (≈17.5 mm) inner diameter and three -8 AN ORB ports ensure sufficient flow for high-power applications.
• Conversion to 14 mm top feed: allows use of high-performance injectors (e.g. ID1050X, ID1300X, ID1700X, ID2600X) without manifold modifications.
• POM insulating spacers reduce heat transfer from the intake manifold, reducing the risk of fuel evaporation.
• Compatible with gasoline, E85 and methanol thanks to anodized aluminum and Viton® seals.
• Aluminum IACV spacer + hose and spigot included, allowing the idle bypass to be routed outside the manifold for trim clearance.
• Ports fit pulsation dampeners, FPR regulators and Radium gauges mounted directly on the trim (optional accessories).
