950 Billet Turbo Upgrade for Mercedes-AMG M157 | High-Power Turbo Set

High-Level Overview:

These turbos retain the factory AMG turbo housings for perfect bolt-on fitment, while replacing and upgrading every internal component that actually affects airflow, boost, and durability.

The result: OEM fit and finish with performance far beyond stock.

What You’re Actually Getting

• Billet compressor wheels for increased airflow and efficiency
• Upgraded turbine wheels to support higher exhaust flow and sustained boost
• Completely replaced internal rotating assemblies (not refreshed)
• Precision CNC machining to optimize clearances and airflow paths
• High-speed VSR balancing for smooth, reliable operation at elevated RPM and boost
• OEM Mercedes-AMG turbo housings reused to ensure factory mounting, oiling, and coolant routing

Wolf in sheeps clothing. OEM housing; internals are fully upgraded.

Technical Configuration

Featuring a 54mm billet compressor wheel paired with a 53mm upgraded turbine wheel, this setup is engineered for high-output M157 engines that demand strong top-end power without sacrificing fitment or drivability.

By retaining OEM housings, heat management and exhaust geometry remain exactly as Mercedes-AMG intended, while internal airflow and boost capability are dramatically increased.

Vehicle Compatibility

• Mercedes-Benz S63 AMG (M157)
• Mercedes-Benz CL63 AMG (M157)
• Mercedes-Benz CLS63 AMG (M157)
• Mercedes-Benz E63 AMG (M157)

Recommended Supporting Upgrades

To fully utilize the airflow and power potential of these turbos, supporting modifications are strongly recommended. These upgrades help ensure reliability, consistency, and proper boost control.

• Catless Downpipes: Reduce exhaust backpressure and allow the upgraded turbines to operate efficiently.
• Aluminum Intake Tubes: Remove restrictive factory inlet piping and improve turbo response under high boost.
• Performance Radiator: Increased cooling capacity for high-power and sustained-load driving.

Core Return & Core Deposit

This upgrade utilizes OEM AMG turbo housings. A core deposit is required unless your stock turbos are sent in advance.

• Select “Core Deposit” to keep your vehicle operational during the build
• Select “Send Cores in Advance” if shipping your turbos prior to work beginning
• The core deposit is fully refunded once acceptable cores are received

• Wastegate actuators must be removed before shipping
• Prompt shipping helps prevent processing delays

Bottom line: You retain factory AMG fitment and reliability by keeping OEM housings, while gaining significantly increased airflow and power capability through fully upgraded internals.
