If you're looking to enhance your Nissan Silvia S14 or S15 SR20DET, the Radium Engineering Fuel Rail Top Feed Conversion is just what you need. This fuel rail is expertly crafted to fit seamlessly with the OEM intake manifold of your SR20DET, ensuring a perfect match for your engine setup.
Manufactured with a generous 0.69" internal bore, this fuel rail is built to handle all your engine's power needs. It's CNC machined from solid 6061 aluminum and finished with a sleek black anodized coating, giving it a high-quality look and feel. Plus, the included insulating spacers help mount the rail to the OEM intake manifold, providing thermal isolation to keep everything running smoothly.
One of the standout features of this fuel rail is its ability to convert your OEM side feed fuel injector setup to a top feed configuration. This allows you to use high-flow fuel injectors (not included), making it a great choice for those looking to push their engine's performance. The fuel injector bores are designed with a 14mm ID, ensuring compatibility with a range of injectors.
To ensure longevity, the lower billet aluminum injector seats are anodized and laser etched to resist oxidation and corrosion. They are O-ring sealed and specifically designed for 14mm top feed injectors, making installation a breeze. This kit is versatile too, as it works with all fuel types, including popular alcohol mixtures like E85.
Replacing the OEM 2-bolt IACV bypass hard line is simple with the included billet aluminum IACV spacer kit, which provides the necessary clearance for the top feed fuel rail. An anodized aluminum barb adapter and rubber hose are also included to reroute the charge pipe hose externally to the manifold, ensuring everything fits just right. You'll receive a gasket for the IACV spacer as well, making for a complete package.
When you choose the Radium Engineering Fuel Rail, you can expect a hassle-free installation with all the necessary components included:
