T3 turbocharger flange, 44mm MVR wastegate flange, and thick Schedule 10 weld-el piping for serious durability. The geometry is purpose-designed to retain A\/C and power steering on the SR20DET, which is rare for a top-mount manifold and a major win for street-driven swaps.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eTop-mount manifolds position the turbo above the engine rather than below it, which gives you better packaging for high-mounted intercooler piping, easier access for service, and visual presence. The tradeoff on most top-mount manifolds is that A\/C and power steering have to come out to make room. The ISR RamHorn solves that problem with a specific geometry that routes around both accessories, so you can run a top-mount turbo on a street-driven S-Chassis without giving up A\/C or power steering.\u003c\/p\u003e\n\n\u003cp\u003eSchedule 10 weld-el piping is significantly thicker than typical aftermarket tubular manifolds, which means better resistance to thermal cracking and longer service life under heat cycling. This is the upgrade over the V3 bottom-mount SCH10 manifold for builds going top-mount.\u003c\/p\u003e\n\n\u003ch3\u003eCritical Specs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eT3 turbocharger flange\u003c\/strong\u003e (matches Garrett T3 and T3\/T4 hybrid turbos)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e44mm MVR external wastegate flange\u003c\/strong\u003e (matches TiAL MVR 44mm and equivalent external wastegates)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSchedule 10 weld-el piping\u003c\/strong\u003e (thicker than standard tubular)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eA\/C and power steering compatible\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eRecommended Companion Parts\u003c\/h3\u003e\n\u003cp\u003eTo build a complete top-mount SR setup around this manifold, plan for:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eT3-flange turbocharger (ISR RSX3076 ball bearing, ISR RSX3582, or similar)\u003c\/li\u003e\n\u003cli\u003eExternal wastegate with 44mm MVR flange\u003c\/li\u003e\n\u003cli\u003eISR O2 housing for top-mount SR20DET manifold\u003c\/li\u003e\n\u003cli\u003eISR Downpipe for SR20DET S13\/S14\u003c\/li\u003e\n\u003cli\u003eOil restrictor (required for dual ball bearing turbos)\u003c\/li\u003e\n\u003cli\u003eOil drain flange (GT Series with integrated -10AN)\u003c\/li\u003e\n\u003cli\u003eISR Hot Side Top Mount IC Piping Kit (works with standard S-Chassis ISR intercooler kits)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNissan SR20DET S13 (Redtop)\u003c\/li\u003e\n\u003cli\u003eNissan SR20DET S14 (Notchtop and Blacktop)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x ISR Performance RamHorn top-mount turbo manifold, Schedule 10\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e ISR Performance\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e IS-SSHT-NS13\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eType:\u003c\/strong\u003e Tubular Top Mount Turbo Manifold (RamHorn)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eEngine Fitment:\u003c\/strong\u003e Nissan SR20DET (S13 and S14)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eConstruction:\u003c\/strong\u003e Tubular, Schedule 10 weld-el piping\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eTurbocharger Flange:\u003c\/strong\u003e T3\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eWastegate Flange:\u003c\/strong\u003e 44mm MVR (external wastegate required)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eA\/C Compatible:\u003c\/strong\u003e Yes\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003ePower Steering Compatible:\u003c\/strong\u003e Yes\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eApplication:\u003c\/strong\u003e Top-mount turbo builds chasing serious power while retaining street accessories\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eSold:\u003c\/strong\u003e Individually\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eLegality:\u003c\/strong\u003e Off-road and competition use only\u003c\/p\u003e","brand":"ISR Performance","offers":[{"title":"Default Title","offer_id":45957132058821,"sku":"IS-SSHT-NS13","price":770.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/2718\/9701\/files\/IMG_6393__01388.1630073069.500.659.jpg?v=1773346480","url":"https:\/\/www.isrcompetition.com\/products\/isr-performance-ramhorn-top-mount-manifold-mvr-sch10-nissan-sr20det-s13-s14","provider":"ISR Competition","version":"1.0","type":"link"}
