Stage 1 Turbo Upgrade for Mercedes-AMG M177 – C63 / C63 S / AMG GT
OEM-based BorgWarner rebuild • Big power gains • Stock-like drivability
The 900 C63 / AMG GT Stage 1 Turbo Upgrade is designed for enthusiasts who want a meaningful jump in power without sacrificing reliability. Built using OEM BorgWarner rebuild kits, this upgrade delivers substantial WHP and WTQ gains while retaining factory-like response and durability.
This is not an oversized race turbo or experimental setup. It’s a refined, proven Stage 1 solution for the Mercedes-AMG M177 4.0L BiTurbo platform—ideal for aggressive street builds, tuned daily drivers, and performance-focused AMG owners.
A core deposit is required for your stock turbochargers unless you send your factory turbos in advance. If you ship your cores to us first, the core deposit is not needed (or will be refunded once your usable cores are received and verified).
Key Benefits
- Significant gains in wheel horsepower and torque over stock turbos
- Built with OEM BorgWarner internals for long-term reliability
- Improved airflow and boost efficiency without extreme lag
- Designed to support tuned M177 setups and supporting mods
- Maintains drivability suitable for street and spirited use
Vehicle Fitment
- Mercedes-AMG C63 (M177)
- Mercedes-AMG C63 S (M177)
- Mercedes-AMG GT (M177)
Engine: M177 4.0L BiTurbo
Application: Stage 1 turbo upgrade (tuning required)
If you receive turbochargers equipped with wastegates, do not use the supplied wastegate units. There is no guarantee on their condition or calibration. You must reuse your factory wastegates to ensure proper operation, reliability, and known functionality.
This turbo upgrade is best suited for owners looking to push beyond stock performance while keeping the core character of the AMG intact. If you want your C63 or AMG GT to pull harder, respond faster under boost, and fully take advantage of tuning and supporting mods—this is the right move.
Performance-focused builds • Proven components • Fitment support available
