Stage 1 Turbo Upgrade — Mercedes-AMG C63 & C63 S (W205)

M177 4.0L V8 BiTurbo • OEM BorgWarner rebuild • Stock-like drivability

The Stage 1 Turbo Upgrade for the W205 C63 and C63 S is built for owners who want a serious jump in power without giving up reliability or daily drivability. Built on OEM BorgWarner rebuild kits, it delivers substantial wheel horsepower and torque gains while keeping factory-like response.

This is not an oversized race turbo or an experimental setup. It is a refined, proven Stage 1 solution for the M177 4.0L V8 BiTurbo — ideal for aggressive street builds, tuned daily drivers and owners building toward more later.

Core Deposit: a core deposit is required for your stock turbochargers unless you send your factory turbos in advance. Sending cores in advance is the lower price — choose the option that suits you above.

Key Benefits

  • Significant wheel horsepower and torque gains over the factory turbos
  • OEM BorgWarner internals for long-term reliability
  • Improved airflow and boost efficiency without extreme lag
  • Retains the drivability that makes the C63 usable every day

Vehicle Fitment

  • Mercedes-AMG C63 (W205) — M177 4.0L V8 BiTurbo
  • Mercedes-AMG C63 S (W205) — M177 4.0L V8 BiTurbo

Important Wastegate Notice:
If your turbochargers arrive with wastegates fitted, do not use the supplied wastegate units — their condition and calibration are not guaranteed. Reuse your factory wastegates for known, reliable operation.

What These Turbos Need

Tuning is required; the factory calibration has no strategy for these turbos. The rest controls heat and airflow so the turbos deliver what they are capable of.

Core Return

  • Core return required — remove your factory wastegate actuators before shipping
  • The core deposit is fully refunded once acceptable cores are received
