The BMW 3 Series is a popular choice among car enthusiasts, especially the 330i model. However, many owners seek to enhance their vehicle’s performance to match the excitement of the M340i. One of the most effective ways to achieve this is through a turbocharger swap. In this article, we will explore the costs associated with this upgrade and the expected results.
Understanding the Turbocharger Swap
A turbocharger is a device that increases an engine’s efficiency and power output by forcing extra air into the combustion chamber. For BMW 330i owners, swapping the stock turbocharger for a more powerful unit can significantly boost performance, bringing it closer to M340i specifications.

In total, the cost of a turbocharger swap can range from approximately $2,600 to $6,300, depending on the choices made and the shop performing the work.
Expected Results from the Swap
Swapping the turbocharger can lead to impressive performance gains. Here’s what you can typically expect:
- Horsepower Increase: Expect an increase of 50-100 horsepower, bringing the total closer to the M340i’s output.
- Torque Increase: Torque can also see a significant boost, enhancing acceleration and responsiveness.
