Sourcing genuine Nissan parts for RB engines has gotten harder and more expensive as the JDM scene has grown, and this pump performs identically to the factory unit at a fraction of the price. Built to the factory pump's dimensional spec including the gasketless interface.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eThe water pump is a wear item on any RB engine. Bearings wear, seals fail, and a leaking water pump on a built RB is one of the worst possible reasons to be stranded. This pump is the right replacement choice when you need to refresh an aging RB without paying genuine Nissan dealer prices for parts that, for the JDM-only RB engines, often have to be ordered from Japan.\u003c\/p\u003e\n\n\u003cp\u003eThis is not a genuine OEM Nissan pump. It's an aftermarket OE Replacement built to the same spec and intended to replace the factory pump in a refresh, rebuild, or service job.\u003c\/p\u003e\n\n\u003ch3\u003eCritical Installation Note\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSilicone gasket maker required for installation.\u003c\/strong\u003e The factory RB25DET and RB26DETT water pump design does NOT use a paper or rubber gasket between the pump and the block. This pump follows that same design. Use a quality silicone gasket maker (Permatex Ultra Grey, Three Bond, or similar) when installing. Skipping the gasket maker will result in a leaking pump.\u003c\/p\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNissan RB25DET (Skyline GTS-t R33, GTS-t R32)\u003c\/li\u003e\n\u003cli\u003eNissan RB26DETT (Skyline GT-R R32, R33, R34)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eRB25DET and RB26DETT only.\u003c\/strong\u003e Not compatible with RB20DET, RB25DE (naturally aspirated), or RB26-based variants outside the DETT.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x OE replacement water pump for RB25DET \/ RB26DETT\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 OE-21010-24U26\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eType:\u003c\/strong\u003e Engine Water Pump (OE Replacement)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eEngine Fitment:\u003c\/strong\u003e Nissan RB25DET, RB26DETT\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eOEM vs Aftermarket:\u003c\/strong\u003e Aftermarket OE-style replacement (not genuine Nissan)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eGasket:\u003c\/strong\u003e None - requires silicone gasket maker for installation\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eApplication:\u003c\/strong\u003e Engine refresh, rebuild, or worn pump replacement\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":45957132091589,"sku":"OE-21010-24U26","price":71.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/2718\/9701\/files\/RB25_Water_Pump__89255.1630073070.500.659.jpg?v=1773346730","url":"https:\/\/www.isrcompetition.com\/products\/isr-performance-oe-replacement-water-pump-nissan-rb25det-rb26dett","provider":"ISR Competition","version":"1.0","type":"link"}
