Description

The Radium Engineering Fuel Rail is a top-feed conversion kit designed for the Nissan SR20DET S14 and S15 engines. It allows for the use of high-flow aftermarket fuel injectors by converting the OEM side-feed setup to top-feed. The rail is CNC machined from 6061 aluminum with a 0.69-inch internal bore to support high engine power requirements.

This kit includes billet aluminum injector seats that press into the intake manifold, providing a sealed base for the top-feed injectors, which require specific 34mm height and 14mm upper and lower O-rings. It also features insulating spacers for thermal isolation and an IACV spacer kit to reroute the charge pipe hose externally. The fuel rail has three 8AN ORB ports for additional fittings.
