High-performance GT1752S replacement turbocharger for Kia Sorento and Hyundai H-1 / Starex 2.5L CRDi engines. Engineered with a dynamically balanced CHRA and premium bearing housing to solve underboost lag and eliminate turbine shaft snapping. OEM: 28200-4A101 | Cross ref: 733952-0001.
In stock for workshop and fleet supply.
The Kia Sorento Turbocharger (OEM 28200-4A101) is a critical automotive engine core part engineered to sustain the thermal and mechanical stresses of the 2.5-liter D4CB CRDi diesel engine series. Powering high-use family SUVs of the Kia Sorento (2002–2006) and light commercial fleets of the Hyundai H-1 / Starex, this GT1752S wastegate turbocharger operates under continuous stop-and-go load cycles. In these 140 HP common-rail diesel platforms, the primary failure mode is immediate turbine shaft snapping. This catastrophic failure is typically driven by severe oil starvation, occurring when hot shutdowns bake stagnant oil into carbonized sludge inside the narrow oil feed galleries. Furthermore, soot accumulation in the wastegate bypass valve triggers severe linkage stiction, leading to sluggish acceleration and underboost lag.
To resolve these premature failures, Ruich Value produces this GT1752S turbocharger with heavy-duty material and mechanical upgrades. The turbine housing is cast from high-silicon ductile iron, offering vastly superior resistance to thermal cracking under continuous 750°C exhaust gas temperatures compared to standard cast iron. The turbine wheel is manufactured from premium K18 alloy to prevent blade tip erosion. Every central housing rotating assembly (CHRA) undergoes precise dual-plane high-speed dynamic balancing on Schenck machines under 150,000 RPM, completely eliminating high-frequency harmonic vibrations. For automotive machine shops, fleet operators, and global distributors seeking a reliable, direct-fit replacement, our factory-calibrated wastegate turbocharger restores original 103 kW torque curves and fuel efficiency.

Oil starvation and turbine shaft snapping in early Sorento D4CB engines are typically caused by carbon sludge clogging the turbo oil feed line. The D4CB CRDi engine is highly prone to carbon blow-by if injector copper crush washers are leaking. This carbon sludge mixes with engine oil, forming carbon deposits that settle inside the narrow oil feed line, restricting oil flow to the turbo bearing housing. Under high-speed boost, this oil starvation causes immediate shaft scoring and bearing wear, leading to axial play and eventual shaft snapping. Ruich Value highly recommends replacing the oil feed line with every turbo installation to prevent recurring shaft snapping.
No, they are completely incompatible. The 28200-4A101 is a wastegate turbocharger (WGT) designed for early Euro 3 D4CB engines producing 140 HP. Late-generation D4CB engines (such as the 170 HP versions found in 2007+ Sorento models) utilize a Variable Geometry Turbocharger (VGT) with an electronic or vacuum-actuated nozzle ring. The WGT and VGT models utilize entirely different exhaust manifold flange configurations, water jacket connections, and ECU engine mapping. Attempting to bolt this WGT head onto a VGT engine block will cause incorrect boost signaling and severe mechanical mismatch.
A turbocharger failure deposits microscopic metallic fragments directly into the engine’s oil system. If you do not completely replace the oil feed pipe and thoroughly flush the oil galleries, trapped metallic debris will wash directly into the new GT1752S’s journal bearings on first start-up, causing immediate bearing scoring. Additionally, before starting the engine, you must manually prime the new CHRA by pouring clean engine oil directly into the oil inlet port while manually rotating the compressor wheel. This prevents dry-friction scuffing on the first engine start.
Our GT1752S features a precision-cast turbine housing with a balanced A/R ratio (0.44) that matches the pulsating exhaust gas characteristics of the 2.5L D4CB engine perfectly. Cheap aftermarket housings often have irregular internal surfaces that restrict exhaust gas velocity, creating high backpressure and severe turbo lag. Our high-silicon ductile iron housing ensures smooth exhaust gas flow, which allows the turbine to spool up rapidly at low RPM. This quick spooling restores low-end torque, reduces combustion temperatures, and significantly improves the overall fuel efficiency of the vehicle.
