Hyundai Mighty II Turbo TD05H-14G-10: Specs, Fitment, and Ordering Guide

The Hyundai Truck Mighty II earns its keep on loaded routes, and its 4D34TI diesel leans on the turbocharger for every bit of boost. When the turbo wears out, power drops, fuel burn climbs, and the truck feels flat under load. The TD05H-14G-10 turbocharger (part number 49178-03123) is a direct replacement built for this exact truck and engine pairing.

This guide covers the full spec sheet, fitment, performance numbers, and installation basics. Every figure below comes from the product documentation for this unit, so you can order with the facts in hand.

Technical Specifications

Match every line of this table against your truck before you buy. The engine code on your block is the fastest way to check fitment.

Performance Benefits You Can Feel

Power Output

The headline number first: this turbo can lift engine output by up to 35%. A standard Mighty II 4D34TI makes 136 HP; with the TD05H-14G-10 installed, output reaches up to 184 HP. On a truck that hauls for a living, that difference shows up directly in acceleration and pulling power under load.

Fuel Efficiency

A turbo matched to the engine burns less fuel for the same work. By optimizing the air-fuel mixture and combustion efficiency, the TD05H-14G-10 reduces fuel consumption while holding performance steady. Over a fleet's yearly mileage, that compounds into real operating savings for both fleet operators and owner-operators.

Boost Response

Lag costs time on hills and in traffic. The TD05H-14G-10 design develops boost quickly, so the engine reaches its working output sooner during acceleration and climbing. Drivers feel this most when merging loaded or pulling a grade.

Fitment and Cross-Compatibility

Primary Application

This turbo is built for the Hyundai Truck Mighty II with the 4D34TI engine, a 3.9L diesel known for durability in commercial service. The 49178-03123 unit carries OEM numbers 28230-45100 and 2823045100, so it replaces the stock unit position-for-position. That direct-fit design is what keeps installation simple and performance predictable.

Cross-Compatibility With Fuso Engines

The unit also shows compatibility with Mitsubishi Fuso vehicles running similar 4D34T series engines, and the spec sheet lists the 4D34T4 and D4DA codes as alternatives. If you run a mixed fleet with shared engine platforms, one turbo reference can cover several trucks, which simplifies spare-parts inventory.

Prefer a second listing for the same unit? The Fits Hyundai Truck Mighty 2 TD05H-14G-10 Turbo Turbocharger 49178-03123 page carries the identical turbo and part number, so you can order from whichever listing is in stock.

Installation Notes

Turbos live or die by oil supply. Before you install the 49178-03123, plan the job around the oil system first:

• Make every oil line connection clean and tight — restricted oil flow is the fastest way to shorten turbo life.
• Follow the manufacturer-recommended break-in procedure before loading the engine hard.
• Torque all fasteners to spec and check for leaks at first startup.
• Professional installation is recommended to maximize performance and longevity.

An experienced mechanic can handle the swap in a shop, but the recommendation stands: correct oil lines and a proper break-in protect both the turbo and your 12-month warranty coverage.
