Expert's advice:

The Mosselman Upgrade Turbocharger (MSL75-95) for the BMW S58 engine combines a huge boost in performance with an unmatched spool. Our S58 turbocharger set does not only make your car faster, it is designed to make the car feel better to drive: smoother, stronger and more alive. ​Airflow is the core of every Mosselman design. By increasing airflow and reducing backpressure, our turbos deliver faster spool, stronger mid-range performance and clean, consistent power right up to the redline, with boost that builds naturally, without lag, surges or sudden steps. Resulting in a predictable, controlled and seamlessly integrated driving experience. Depending on the modifications done to the car and fuel type, this turbo set can deliver up to 950hp!

Thanks to their OEM origins, the set is easy to install and requires no additional modification. The Mosselman S58 Turbocharger Set is designed for the BMW G8x platform equipped with the S58 engine and can be configured with flow-optimized custom intakes for use with the stock intake, as well as Eventuri or Mishimoto air intake systems. If you have any doubts about your turbocharger version, feel free to contact us.

Note: This turbocharger set is compatible with an Mishimoto air intake. If you are using an OEM or Eventuri intake, please select the appropriate version below.

At Mosselman Turbo Systems, every performance turbo begins with precision engineering.

The compressor wheels are CNC-milled from forged billet aluminum for maximum strength and airflow efficiency, while the turbine wheels are built from Inconel or MAR–M to withstand extreme exhaust gas temperatures. Each component is machined to exact tolerances before being assembled into the CHRA, the core of the turbo where strength, sealing and smooth rotation are critical.

Balancing is the defining step in our process. Our turbos operate at speeds up to 200,000 rpm, so every wheel is balanced individually before the complete CHRA is high-speed balanced under oil pressure to replicate real-world conditions. Microscopic corrections are made until the core runs flawlessly, ensuring fast spool, stable boost and long term durability.

The result is a compact, high-performance unit that delivers predictable response, clean power delivery and the reliability Mosselman is known for. Engineered to elevate BMW engines far beyond their factory limits.
