The \u003cstrong\u003eRadium Engineering Top Feed Fuel Rail Conversion Kit for the Nissan SR20DET (S14\/S15)\u003c\/strong\u003e is the definitive fix, designed specifically for the S14\/S15 OEM intake manifold: a 0.69\" internal bore rail CNC machined from solid 6061 aluminum, black anodized, converting the engine to 14mm ID top feed injection. Green anodized billet injector seats press into the manifold providing a sealed base, phenolic spacers thermally isolate the rail at the OEM bosses, and the kit even solves the IACV problem, replacing the OEM 2-bolt bypass hard line with a machined spacer, barb adapter, hose, and gasket. All fuels including E85. S13 SR20DET uses Radium's separate kit.\u003c\/p\u003e\n\u003ch3\u003eWhat You'll Feel\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModern top feed injectors from ID850 through ID2600 unlocked on the SR\u003c\/li\u003e\n\u003cli\u003eFuel delivery that stays consistent under high pressure where the restrictive OEM rail chokes\u003c\/li\u003e\n\u003cli\u003eA complete, leak-free conversion, with the IACV rerouting engineered instead of improvised\u003c\/li\u003e\n\u003cli\u003eCooler fuel from phenolic isolation between rail and manifold\u003c\/li\u003e\n\u003cli\u003eBoost-sealed injector bases via O-ring sealed press-in billet seats\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned specifically for the SR20DET S14\/S15 OEM intake manifold; converts side feed to top feed\u003c\/li\u003e\n\u003cli\u003e0.69\" internal bore, CNC machined solid 6061 aluminum, black anodized\u003c\/li\u003e\n\u003cli\u003e14mm ID injector bores; requires 34mm tall universal injectors with 14mm upper and lower O-rings (not included)\u003c\/li\u003e\n\u003cli\u003e4x Radium 20-0161 green anodized 25mm billet injector seats, O-ring sealed, press into the manifold\u003c\/li\u003e\n\u003cli\u003eIACV solution included: 20-0162 black anodized spacer kit, 18-0014 gasket, barb adapter, hose, and OEM clamp reroute the charge pipe hose externally\u003c\/li\u003e\n\u003cli\u003e3x phenolic spacers and washers, stainless M8x1.25 and M6x1 bolts; all fuels including E85; fittings NOT included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Details\u003c\/h3\u003e\n\u003cp\u003eInjector selection is fully documented, which removes the usual conversion guesswork: the rail requires a 34mm tall universal injector with 14mm O-rings top and bottom, a configuration most major suppliers offer, with direct fitments including the Injector Dynamics ID1050, ID1300, ID1700, and ID2600 in XDS-34-14-14 form plus the ID850 and ID2000 34-14-14 family and Evolved Injection DPI options. The IACV hardware is the part other conversions skip, since the factory idle valve's bypass hard line occupies rail territory, and Radium's spacer, gasket, and barb adapter relocate that plumbing cleanly rather than leaving it to the builder. Note that top feed injectors designed for 11mm bores can also work by switching their top O-rings to 14mm style. Ports are covered separately: this kit ships without fittings, so select Radium 8AN ORB adapters, a regulator, and a damper per your system plan.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Black anodized aluminum fuel rail\u003c\/li\u003e\n\u003cli\u003e3x Phenolic mounting bolt spacers and 3x washers\u003c\/li\u003e\n\u003cli\u003e4x Radium 20-0161 green anodized 25mm injector seats\u003c\/li\u003e\n\u003cli\u003e1x Radium 20-0162 IACV spacer kit, 1x 18-0014 IACV gasket, IACV barb adapter, rubber hose, and OEM clamp\u003c\/li\u003e\n\u003cli\u003e3x Stainless M8x1.25 and 3x M6x1 mounting bolts\u003c\/li\u003e\n\u003cli\u003eInjectors and port fittings NOT included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1995-2002 Nissan Silvia \/ 240SX S14 and S15 with SR20DET (OEM intake manifold)\u003c\/li\u003e\n\u003cli\u003eSR20DET swap applications using the S14\/S15 manifold; S13 manifolds use Radium's separate S13 kit\u003c\/li\u003e\n\u003cli\u003e34mm top feed injectors with 14mm upper and lower O-rings\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672696094787,"sku":"20-0359","price":275.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0159-28681824239686_b92bb421-60ac-490c-b38f-f3bd25fe7caf.jpg?v=1786717157","url":"https:\/\/www.tunedbyshawn.com\/products\/1995-2002-nissan-s14-15-sr20det-fuel-rail-kit-by-radium-engineering-20-0359","provider":"Tuned by Shawn","version":"1.0","type":"link"}
