Technical characteristics of the N55B30A engine

The offered bare engine block belongs to the family of modern BMW inline petrol units. The engine is designed to run on petrol fuel, and its construction is based on a multi-cylinder layout, ensuring high refinement and smooth power delivery. The N55B30A engine code is widely known in the BMW community as a base for dynamic yet comfortable powertrain configurations.

The cylinder layout has been designed for even load distribution and stable operation across the entire rev range. As a result, the block performs well both in daily use and in more demanding applications, such as software modifications or light mechanical tuning (after proper preparation and condition inspection).

New timing chain – a key operational advantage

A significant advantage of this unit is the new timing chain system, which significantly increases its utility value. In practice, this means reducing the risk of typical failures associated with a worn-out timing system and enabling safer operation after installation in the vehicle. For workshops and end-users, this translates into:

• reduced costs of additional service work after installation,
• greater peace of mind during the initial period of use,
• better predictability of the unit's performance with proper oil maintenance.

Combining the new timing system with the N55B30A engine design makes this block an attractive base for engine replacement in F-series BMW cars with this generation of petrol engines.

Application in BMW F30, F31, F34, F32, 335i and 435i models

The presented block is intended for installation in selected BMW 3 and 4 series models, such as the F30, F31, F34, and F32 in 335i and 435i versions, factory-equipped with the N55 engine. Consequently, it serves as a coherent solution for:

• replacing a damaged engine in cars from the same engine family,
• restoration projects where preserving the original BMW specification is a priority,
• vehicle modernization based on an original, structurally compatible block.

The bare block allows for the use of existing accessories from the previous engine, which facilitates fitting to a specific vehicle configuration and reduces the need to search for additional components.

Condition, mileage, and potential for further use

The engine comes from the secondary market, meaning it is a used component, but with preserved potential for further operation after proper installation and verification by a workshop. The declared mileage of the unit allows for assessing its service history and planning any additional maintenance tasks (e.g., checking seals, compression testing, lubricating system inspection) before installation in the target vehicle.

For professional workshops and informed users, this is a beneficial solution – they receive a complete bare block with a new timing system, which can be thoroughly checked, prepared, and integrated with existing accessories, maintaining full control over the quality of the work performed.

Selection, compatibility, and technical support

When selecting this engine, it is crucial to verify the compatibility of the unit code and vehicle generation to ensure full integration with the car's electronics, accessories, and drivetrain. The product has an assigned OEM part number and associated interchangeable numbers, which facilitates precise identification in BMW catalogs and service systems.
