High-performance GT1749S (industry reference: GT17-9W) replacement turbocharger for Hyundai Porter H100, Grace, and H200 2.5L D4BH / 4D56TCi engines. Engineered with a dynamically balanced CHRA to resolve underboost lag and eliminate turbine shaft snapping. OEM: 28200-42610 | Cross ref: 715924-0001.
In stock for fleet supply and export.
The Hyundai Porter Turbocharger (OEM 28200-42610), also designated in manufacturing catalogs as GT17-9W, is a critical automotive engine core part engineered to sustain the thermal and mechanical loads of the 2.5-liter D4BH and 4D56TCi diesel engines. Frequently deployed in high-utilization commercial fleets of the Hyundai H100 Porter light trucks and Grace passenger vans, this GT1749S wastegate turbocharger operates under continuous heavy-cargo hauling cycles. In these light-duty logistics transport vehicles, the primary failure mode is immediate turbine shaft snapping. This catastrophic failure is typically driven by severe oil starvation, occurring when hot shutdowns coke the oil within the narrow feed lines. Additionally, exhaust 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 GT1749S 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 workshops, fleet operators, and global distributors seeking a reliable, direct-fit replacement, our factory-calibrated wastegate turbocharger restores original 100 HP torque curves and fuel efficiency.

Oil starvation and turbine shaft snapping in H100 Porter D4BH engines are typically caused by carbon sludge clogging the turbo oil feed line. The D4BH/4D56TCi 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.
The GT1749S (28200-42610) represents a higher-capacity wastegate turbocharger designed for Euro 3 intercooled D4BH / 4D56TCi engines producing 100 HP. In contrast, older naturally aspirated or low-boost 2.5L engines used the smaller TD025M or TD04 turbochargers. The GT1749S and TD025M utilize entirely different exhaust manifold flange configurations, water jacket connections, compressor outlet angles, and wastegate pressure relief thresholds. Attempting to install this GT1749S head onto an older TD025M block will cause timing belt alignment issues 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 GT1749S’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 GT1749S features an integrated water-cooled bearing core jacket that connects directly to the engine’s coolant circuit. In commercial vehicles like the Porter H100 truck, heavy-load cargo hauls raise internal turbo temperatures significantly. When a driver shuts off the engine immediately after a hard run, oil remaining inside an oil-only turbo will instantly bake and carbonize, forming hard sludge that scores the bearings during subsequent starts. The water-cooling jacket continues to dissipate residual heat through a natural thermosiphon effect after engine shutdown, completely preventing oil carbonization and significantly extending bearing life.
