Stage 3 turbocharger upgrade engineered for the Mercedes-AMG M178 4.0L twin-turbo V8 platform (GT/GTC/GTS/GTR) — a complete drop-in performance upgrade that transforms the engine's response and top-end capability without sacrificing reliability. Upgraded internals hold boost and spool aggressively where the factory units give up, with proven power capability up to 900+ HP.

Each turbo is CNC-machined in-house to strict tolerances and features upgraded billet compressor wheels, an upgraded turbine wheel, and ceramic-coated housings to manage extreme exhaust gas temperatures. All supporting internals are uprated to match.

  • Upgraded billet compressor wheel: Higher airflow capacity, faster spool
  • Upgraded turbine wheel: Improved efficiency under high exhaust flow
  • Ceramic-coated housing: Manages extreme EGTs and improves underhood thermal management
  • Upgraded internals: Uprated bearings and shafts for sustained high-boost reliability
  • CNC-machined: All components precision-machined in-house
  • Fitment: Plug-and-play — uses factory mounting, no modifications required
  • Power target: Up to 900+ HP with supporting mods and tune
  • Warranty: 1 year
