High exhaust gas temperatures (EGTs) accelerate oil coking within the center housing rotating assembly (CHRA), starving internal surfaces of adequate lubrication. Additionally, internal wastegate pivot bushings wear loose over time, preventing complete wastegate closure and causing chronic underboost fault codes (P0299), sluggish spool, and exhaust smoke under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM dimensional specifications, this replacement unit features a high-speed balanced CHRA to suppress rotating assembly harmonics and ensure reliable boost delivery. The turbine housing is cast from high-nickel ductile iron to resist thermal distortion, cracking, and wastegate seat erosion. Machined with factory-spec coolant channels, oil inlet ports, and mounting flanges, this turbo integrates directly with existing oil feed, drain, and intercooler piping, restoring the factory mechanical integrity defined by OEM references \u003cstrong\u003e28231-2G410\u003c\/strong\u003e and \u003cstrong\u003e28231-2G420\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 × Turbocharger w\/ Gasket\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;\"\u003e2011-2015 Kia Optima, Sportage\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;\"\u003e2.0L Turbo G4KH (Theta II) \/ TF, SL\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;\"\u003e260-274 hp \/ 269 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;\"\u003e28231-2G400, 28231-2G410, 28231-2G420, 282312G400, 282312G410, 282312G420, 90142-01030, 90142-01031, 9014201030, 9014201031\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\u003e2011-2015 Kia Optima (SX, SXL Trims, 2.0L Turbo Engine)\u003c\/li\u003e\n  \u003cli\u003e2011-2015 Kia Sportage (SX Trim, 2.0L Turbo Engine)\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 TF \/ SL Optima, Sportage?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2011-2015 Kia Optima and Sportage equipped with the \u003cstrong\u003e2.0L Theta II (G4KH)\u003c\/strong\u003e engine; it does not fit naturally aspirated 2.4L or hybrid powertrains.\u003c\/p\u003e\n\n\u003ch4\u003eWhat maintenance must be completed prior to turbocharger installation?\u003c\/h4\u003e\n\u003cp\u003eClean or replace the oil feed and return lines, and complete a fresh engine oil and filter change to prevent residual carbon contaminants from starving the new bearings.\u003c\/p\u003e\n\n\u003ch3\u003eThe Kia Engineering Caliber\u003c\/h3\u003e\n\u003cp\u003eBuilt to factory forced-induction tolerances, this turbocharger withstands the continuous heat and backpressure of the high-compression Theta II platform to deliver dependable manifold pressure and daily driving reliability.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67916389351672,"sku":"DS-EMR696F8M","price":280.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/turbocharger-for-kia-optima-sportage-2011-2015-2-0l-1.jpg?v=1793475343","url":"https:\/\/performancechiptuning.com\/products\/turbocharger-for-kia-optima-sportage-2011-2015-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
