Expert's advice:

Our Stage 2 MSL Upgraded Turbocharger Set for the S55 engine offers a huge boost in performance. By increasing the airflow and reducing backpressure, these turbos increase performance levels significantly without sacrificing reliability. To ensure maximum compatibility, they’re based on OEM quality turbos, but with several components of our own design to ensure the highest quality and reliability. 

Thanks to their OEM origins, the MSL Turbochargers are easy to install and require no additional modification. Of course they work beautifully with our ECU Remaps and the other high-performance parts. Each MSL Turbocharger is manufactured according to Poka-Yoke and ISO standards on the in-house production line. They are subjected to rigorous quality control and VSR reports and come with a limited 1-year warranty.

Stage 2: S55 Upgrade Turbocharger Set

  • Manufactured In-House
    Each Mosselman Turbo upgrade is carefully designed and manufactured at the
    Mosselman Turbo Systems facility in the Netherlands.
  • Low-Lag, High-Boost
    MSL Turbochargers feature fast spool-up combined with high flow-rates to guarantee
    a low amount of lag and a wide powerband.
  • Plug and Play Installation
    Our turbos are designed for plug-and-play installation. Any automotive mechanic should
    be able to replace a stock turbo with one of our high-end units.
  • Low Core Charge
    The core charge is a deposit. This means that you have the option to send your old turbo
    back to us or you can keep it. If you decide to send it to us here then we will refund you
    the core charge after an inspection in our facility.
