Transform your Mercedes-Benz 5.5L V8 Biturbo into an absolute performance powerhouse with our M157 Stage 2 Hybrid Turbo Upgrade. Engineered specifically for elite AMG performance, this direct bolt-on modification delivers an astonishing 800+ HP potential-delivering up to a 50% power increase over factory output.
By combining custom 6+6 billet compressor wheels with high-flow 9-blade turbine wheels, this hybrid turbo set eliminates top-end exhaust restriction while delivering lightning-fast spool-up and relentless pull all the way to redline.
Key Highlights & Performance Benefits
- Massive Power Output: Capable of supporting 800+ HP and extreme torque levels on tuned M157 platforms.
- Custom 6+6 Billet Compressor Wheels: Lightweight CNC-machined wheels maximize air density and transient throttle response.
- 9-Blade High-Flow Turbine: Significantly lowers exhaust backpressure and reduces Exhaust Gas Temperatures (EGTs).
- Direct OEM Fitment: Retains factory housing footprint, oil/coolant lines, and connection points for a clean installation.
- Reinforced Heavy-Duty Bearings: Upgraded journal and thrust bearing assembly built to handle extreme boost pressure.
- VSR Precision Balanced: Core assemblies balanced at high operational speeds for vibration-free reliability.

Engineered for Elite AMG Performance
The factory Mercedes M157 5.5L V8 engine is famous for its massive low-end torque, but the stock turbochargers quickly run out of breath above 5,000 RPM. Our Stage 2 Hybrid Turbo Upgrade solves this bottleneck by re-engineering the factory Biturbo units with enlarged, precision-crafted internals.
1. 6+6 Billet Compressor Wheel
Our custom-milled billet wheel reduces rotational mass, allowing for instantaneous spool-up that preserves the iconic AMG “wall of torque.” The redesigned blade geometry pushes vastly higher air volume at lower temperatures.
2. High-Flow 9-Blade Exhaust Turbine
Stock turbines generate restrictive exhaust backpressure at high boost. Our bespoke 9-blade turbine wheel allows the 5.5L V8 engine to exhale freely, lowering EGTs, enabling safer aggressive tuning, and maintaining violent top-end power straight to the rev limiter.
3. High-Load Reinforced Bearing System
High-boost AMG builds demand superior durability. We upgrade internal thrust and journal bearings to heavy-duty components capable of handling continuous high axial and radial loads.
