Key design features:

• Dedicated to petrol engines – adapting materials and seals to higher exhaust gas temperatures and the specificity of direct injection units.
• Factory supercharging system architecture – retains standard mounting points and connections, reducing the need for hardware modifications.
• Optimal flow characteristics – designed to balance low-rpm dynamics with high-end performance.

Condition, use and benefits of installation

The turbocharger offered is a used part, which represents an attractive cost solution compared to new components. For many Mini and BMW owners, this represents a reasonable compromise between price and maintaining the original manufacturer's specifications.

Choosing a used OEM turbocharger for your B38 petrol engine allows you to:

• restore the correct boost pressure and stable operation of the drive unit,
• maintain factory power and torque parameters,
• avoid fit problems typical of substitutes of uncertain origin.

This solution is particularly recommended for repairs where maintaining the original engine operating characteristics and compatibility with the serial controller software is crucial.
