Direct drop-in upgrade with hose fittings positioned for SR20DET swap routing in the S13 chassis. A cost-effective alternative to premium aluminum radiator brands while delivering comparable cooling performance.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eThe factory S13 radiator was sized for a naturally-aspirated KA24, not a turbocharged SR20DET pushing significantly more heat into the cooling system. As SR20DET swaps make more power and see harder use, the factory radiator becomes a real cooling bottleneck. This aluminum radiator handles the increased heat load on a built SR20DET while staying within a sensible budget.\u003c\/p\u003e\n\n\u003cp\u003eTIG welded aluminum construction throughout, with a direct drop-in fit on the S13 chassis when running an SR20DET swap. Comparable in size and cooling capacity to premium options like Koyo at a significantly lower price.\u003c\/p\u003e\n\n\u003ch3\u003eCritical Fitment Note\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eThis radiator is built for the S13 chassis with an SR20DET engine.\u003c\/strong\u003e The hose fitting positions are sized for SR20DET swap routing, which differs from the factory KA24 layout. For factory KA24DE S13 builds, use the KA24-specific S13 radiator (IS-240KA-RADS13).\u003c\/p\u003e\n\n\u003ch3\u003eRecommended Install Timing\u003c\/h3\u003e\n\u003cp\u003eThe ideal time to install this radiator is during the SR20DET swap itself, while the front of the car is already apart. Adding it later after the swap is finished works, but means you're tearing the front back down for a cooling upgrade that's much easier to do up front.\u003c\/p\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1989-1994 Nissan 240SX (S13) with SR20DET swap\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eBest Paired With a Fan Shroud Kit\u003c\/h3\u003e\n\u003cp\u003eFor the best cooling results, pair this radiator with an aftermarket dual electric fan shroud kit sized to match the radiator.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x ISR Performance aluminum radiator (S13 SR20DET fitment)\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-240SR-RADS13\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eType:\u003c\/strong\u003e Performance Aluminum Radiator\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eVehicle Fitment:\u003c\/strong\u003e 1989-1994 Nissan 240SX (S13) with SR20DET swap\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eEngine Restriction:\u003c\/strong\u003e SR20DET hose routing - use IS-240KA-RADS13 for factory KA24DE\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eMaterial:\u003c\/strong\u003e TIG welded aluminum\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eComparable To:\u003c\/strong\u003e Koyo and similar premium aluminum radiators\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eInstallation:\u003c\/strong\u003e Direct drop-in upgrade\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eApplication:\u003c\/strong\u003e Daily-driven SR20DET-swapped S13 through track and competition use\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eRecommended Pairing:\u003c\/strong\u003e Dual electric fan shroud kit\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":45957127962821,"sku":"IS-240SR-RADS13","price":330.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/2718\/9701\/files\/radiator__95052.1317752052.1280.1280__60788.1630073047.500.659.jpg?v=1773346594","url":"https:\/\/www.isrcompetition.com\/products\/isr-performance-aluminum-radiator-nissan-240sx-s13-89-94-sr20det","provider":"ISR Competition","version":"1.0","type":"link"}
