The Mosselman Upgrade Turbocharger Set (MSL65-80) for the S55 engine combines a huge boost in performance with an unmatched spool. By increasing the airflow and reducing backpressure, these turbos delivered beyond expectation with power levels that literally maxed out the dyno, still with proven reliability. Depending on the modifications done to the car and fuel type, this turbo set can deliver up to 800hp!*

Based on brand NEW MHI turbos, but with several components of our own design to ensure the highest quality and reliability. Thanks to their OEM origins, the set is easy to install and requires no additional modification. The set comes with a limited 1-year warranty.


This product requires a core charge of a set of working set of S55 turbos or a $425 core charge. If paying the $425 core, simply send in your working S55 turbos within 60 days of purchase for a full refund of the $425 core fee.
