Application and compatibility

The presented BMW N47 turbocharger housing has been designed to work with diesel engines used in the 1, 3 and 5 Series. The design corresponds to the factory solution used in the 120d, 320d and 520d versions after modernization (LCI), which allows the original operating characteristics of the supercharging system to be retained.

By maintaining the geometry and mounting points consistent with the factory solution, the housing provides a solid base for:

• regeneration of the existing turbocharger,
• restoring the original configuration after mechanical damage,
• professional repair of the supercharging system without the need to use substitutes with uncertain fit.

Construction and technical characteristics

The turbine housing is responsible for the proper routing of exhaust gases through the turbine wheel, and thus for the stable buildup of boost pressure. The presented component includes:

• factory mounting points for the exhaust manifold and other turbocharger components,
• original geometry of exhaust gas channels, ensuring proper flow and load response characteristics,
• a design prepared to work with the accessories intended for the N47 engine in the 120d, 320d and 520d versions.

This type of element is particularly important in repairs where the factory housing has been cracked, deformed or has suffered excessive thermal wear, and the remaining turbocharger components are still suitable for further use after remanufacturing.

Product Condition and the Benefits of Choosing a Used Case

The turbine housing is offered as a used part, significantly reducing repair costs compared to purchasing a new turbocharger assembly. With proper workshop inspection and any necessary preparation for installation (sandblasting, faceplate inspection, thread check), it represents a rational service solution.

Choosing a used OEM component has several practical advantages:

• original fit for the specific type of turbocharger used in the N47 engine,
• stable operating parameters resulting from maintaining the factory geometry,
• the possibility of economically regenerating an existing turbine instead of replacing the entire assembly.

What is this turbine housing good for?

The turbocharger housing for BMW with the N47 engine will be suitable primarily for:

• workshops specializing in turbocharger regeneration,
• users who have suffered mechanical damage to the housing while maintaining a functional rotor and accessories,
• people who want to restore the original configuration of the supercharging system after unsuccessful modifications or the use of an incompatible substitute.

Before installation, standard workshop procedures are recommended: inspection of the contact surfaces, checking the threads, cleaning the exhaust ducts and checking for any micro-cracks.
