Thermal coking degrades the journal bearing lubrication film, inducing severe shaft play, dynamic oil seal breakdown, and compressor wheel rubbing against the housing. Additionally, the factory wastegate actuator spring softens over time from continuous heat soak, cracking open prematurely and causing erratic manifold pressure, low boost derates, excessive black smoke, and sluggish throttle response under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement turbocharger is engineered to original \u003cstrong\u003eGTA3782BD\u003c\/strong\u003e specifications, incorporating a heavy-wall ductile iron turbine housing and high-efficiency cast alloy compressor wheel to resist thermal distortion under heavy load. The oil-cooled center housing features precision-machined journal and 360-degree thrust bearings to withstand extreme thrust loads and avoid coking. Built with a calibrated pneumatic wastegate actuator rated for engines producing up to 300 hp, it bolts straight to the stock manifold and exhaust downpipe without line modification.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Turbocharger with Wastegate Actuator\u003c\/li\u003e\n  \u003cli\u003e1 Turbine Inlet Flange Gasket\u003c\/li\u003e\n  \u003cli\u003e2 Oil Line Gaskets\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2002-2006 International 4300,4400\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eDT466 \/ DuraStar\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e215-300 hp \/ 560-860 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2506784C91, 1830497C93, 1830499C93, 1836094C93, 1836094C92, 1830497C91, 1830497C92, 751361-1, 751361-6, 715138-9\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2002-2006 International 4300 with Navistar DT466 \/ DT466E 7.6L\u003c\/li\u003e\n  \u003cli\u003e2002-2006 International 4400 with Navistar DT466 \/ DT466E 7.6L\u003c\/li\u003e\n  \u003cli\u003eNavistar I530E diesel applications matching listed cross-reference numbers\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the DuraStar 4300,4400?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2002-2006 International 4300,4400 equipped with the \u003cstrong\u003eDT466 \/ DT466E\u003c\/strong\u003e engine. \u003cstrong\u003eDoes not fit non-wastegated GTA3776B \/ GTA3782B turbo systems or 2007+ MaxxForce DT engines with electronic VGT systems.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eIs oil pre-priming required before the first engine startup?\u003c\/h4\u003e\n\u003cp\u003eYes, you must pour clean engine oil into the center housing oil inlet cavity and rotate the compressor wheel by hand prior to startup to prevent dry bearing seizure.\u003c\/p\u003e\n\n\u003ch3\u003eThe International Commercial Standard\u003c\/h3\u003e\n\u003cp\u003eCommercial transport demands sustained boost integrity and thermal endurance under severe gross combined weight ratings; this turbocharger restores the torque delivery, lower exhaust gas temperatures, and continuous hauling reliability demanded by fleet operations.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67610968817912,"sku":"DS-ETO5HRONQ","price":242.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/turbocharger-gta3782bd-for-international-4300-4400-2002-2006-7-6l-1.jpg?v=1791567171","url":"https:\/\/performancechiptuning.com\/de\/products\/turbocharger-gta3782bd-for-international-4300-4400-2002-2006-7-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
