{"product_id":"sr20det-s14-s15-top-feed-fuel-rail-conversion-kit","title":"SR20DET S14\/S15 Top-Feed Fuel Rail Conversion Kit","description":"The Radium Engineering Fuel Rail, Top Feed Conversion, is engineered for the Nissan SR20DET engine found in the S14 and S15 chassis. This kit facilitates the upgrade to high-flow, top-feed fuel injectors, replacing the factory side-feed system.\n\nConstructed from CNC-machined 6061 aluminum with a substantial 0.69-inch internal bore, this fuel rail is built to handle significant power demands. It features anodized and laser-etched billet aluminum injector seats that integrate into the OEM intake manifold, ensuring a secure seal for top-feed injectors. The design specifies a 34mm injector height with 14mm upper and lower O-rings, commonly available from popular aftermarket suppliers. Thermal insulating spacers are included to mount the rail to the OEM intake manifold bosses, providing thermal isolation.\n\nInstallation involves replacing the OEM 2-bolt IACV bypass hard line with an included billet aluminum IACV spacer kit to accommodate the top-feed rail. A barb adapter and rubber hose are provided to reroute the charge pipe hose externally from the manifold. The fuel rail is equipped with three 8AN ORB ports, allowing for the connection of various accessories such as fuel pressure regulators, gauges, and pulse dampers; appropriate fittings must be selected based on application and clearance.\n\nThis kit is compatible with all fuel types, including alcohol mixtures like E85. It is important to note that fuel injectors are not included with this kit. The system is specifically designed for the SR20DET S14\/S15 OEM intake manifold.","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":52663426974008,"sku":"RAD20-0359","price":275.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687532199.jpg?v=1784326800","url":"https:\/\/store.motormia.co\/products\/sr20det-s14-s15-top-feed-fuel-rail-conversion-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
