PTG X M177.1 Exhaust Manifold + M177.2 Turbine Housing Conversion Set

Take the M177.1 platform beyond the limitations of the factory turbo and manifold configuration with the PTG X M177.1 Exhaust Manifold and M177.2 Turbine Housing Conversion Set, available through Zefer Performance.

This system was engineered by Premier Tuning Group for high-output M177.1 and M178 builds that need the airflow and turbo compatibility required for serious power. The conversion allows M177.1-equipped vehicles to use larger M177.2-style turbochargers, including compatible OEM and PTG M177.2 turbo configurations.

What Makes the PTG X-Manifold Different

• Investment-cast Inconel construction for high-temperature durability
• 4-to-1 collector design engineered for improved exhaust flow
• PTG reports a 59% flow increase with the replacement M177.1 manifold design

• Allows compatible PTG or factory M177.2 turbo fitment on M177.1-equipped engines
• Designed to support increased boost, airflow and high-horsepower applications
• Developed, tested and validated in-house by PTG

Fitment / Application

Designed for Mercedes-AMG applications using the M177.1 / M178 4.0L twin-turbo V8 where an M177.2 turbo conversion is desired. This is a specialized performance component, so Zefer Performance strongly recommends confirming the complete vehicle and turbo setup before ordering.

PTG Part Number: 009-0906-4510

Installation

PTG describes the system as a 100% bolt-on application when used in the intended configuration. Because this conversion involves the turbocharger and exhaust manifold system, professional installation by an experienced Mercedes-AMG performance shop is strongly recommended.

Important: Supporting modifications, tuning and fuel-system requirements depend on the vehicle, turbo setup and desired power level. Contact Zefer Performance with your VIN, current modifications and power goals before ordering so we can help verify the correct configuration.
