Technical characteristics of the BMW N55 turbocharger housing

This turbocharger housing for the BMW E90 LCI and F20 with the N55 engine is a fundamental structural element of the turbocharger system. It ensures proper exhaust and charge air routing, as well as a stable turbo core seat. By maintaining factory design parameters, it allows for the restoration of the turbocharger's original operating conditions, resulting in correct boost pressure and predictable torque characteristics.

The housing is designed for use in systems based on the N55 engine, where precise fit with the manifold, oil and coolant lines, and exhaust components is crucial. Proper channel geometry influences efficient exhaust and air flow, which is crucial for both performance and the durability of the entire supercharging system.

Application in BMW E90 LCI and F20 with N55 engine

The BMW E90 LCI and BMW F20 with the N55 engine utilize a turbocharger as a key component to increase engine power and flexibility. A properly selected turbo housing is essential for:

• repair of a damaged turbocharger while maintaining the original configuration,
• regeneration of the charging system using OEM parts,
• restoring serial operating parameters after modifications or failures.

A used component with preserved material structure allows for cost-effective turbocharger rebuilds without the need to purchase a complete new kit. This solution is particularly beneficial for service projects and modifications where maintaining the factory hardware is crucial.

Used condition and the benefits of using OEM parts

The turbocharger housing is in used condition, meaning it was removed from the original BMW system. This component provides:
