Mercedes-Benz M157 Stage 2 Hybrid Turbo Upgrade | S63 E63 CL63 AMG | 800+ HP

Serious Performance Upgrade

The M157 V8 engine is a torque monster, but the factory turbochargers quickly become the limiting factor when chasing elite performance levels. Our Stage 3 Hybrid modification re-engineers the factory Biturbo system into a high-flow powerhouse. By integrating significantly larger internals and precision-machining the housings, we provide the airflow necessary to unlock up to 370 HP over stock. This is the ultimate upgrade for owners who want their AMG to dominate both the drag strip and the autobahn.

Why This Turbo Wins

• Massive power potential of 800+ HP
• Custom 6+6 Billet compressor wheel for maximum air density
• 9-Blade high-flow turbine wheel to significantly reduce backpressure
• Reinforced journal bearing system to handle extreme boost levels
• CNC machined housings and sealing plates for precision aero fitment
• VSR balanced at maximum operating speeds for total reliability
• Retains the original factory footprint and fitment

Internal Upgrades

• 6+6 Billet Compressor Wheel: Custom CNC-machined wheel designed for a “quick start” response and massive top-end flow.
• 9-Blade High-Flow Turbine: A bespoke exhaust wheel that allows the V8 to exhale efficiently, lowering EGTs and allowing for more aggressive tuning.
• Reinforced Internals: Upgraded thrust and journal bearings specifically designed to maintain stability under the high-load demands of 800+ HP.
• CNC Machining: Both the turbine and compressor housings are profiled to ensure the tightest tolerances for the new, larger wheels.
• VSR Precision Balancing: Each core is balanced at speeds mimicking actual vehicle operation to ensure smooth, vibration-free performance.

Performance Characteristics

The Stage 2 M157 upgrade is designed to enhance the engine’s brutal torque delivery. Thanks to the lightweight billet wheels, spool-up remains incredibly responsive, ensuring that the signature AMG “wall of torque” is preserved. However, the true difference is felt at the top end, where the 9-blade turbine prevents the power drop-off common with stock units, allowing the car to pull violently all the way to the redline.
