M177 Short Block — 1,500HP Forged Build
The M177 Short Block is a fully built foundation for extreme horsepower builds on the Mercedes-AMG M177 4.0L twin-turbo V8. Assembled from the ground up by YPG Motorsport, each short block is machined, balanced, and blueprinted with a forged rotating assembly rated to handle up to 1,500HP without breaking a sweat.
Supplied as a complete short block ready for your heads and accessories — no core exchange required. Ideal for C63, E63, GT, GLC63, and G63 builds pushing well beyond factory limits.

Forged Piston Specification
Every YPG M177 Short Block ships with the same coated forged pistons used in our world-record C63 W205 build and standalone M177 Forged Internals kit:
- Ceramic-Coated Piston Tops — Thermal barrier coating on all 8 piston crowns reduces heat transfer and detonation risk at high boost. Standalone coating service (Swain Tech, Calico) runs $200–400 per set.
- Teflon-Coated Skirts — Anti-friction coating reduces piston-to-wall contact friction and wear under sustained high-RPM operation.
- 4340 Aircraft-Grade Steel — CP-Carrillo or equivalent tier-1 forging house
- Factory Compression Ratio — Maintained for seamless calibration integration
Power Capacity
- Rated to 1,500HP+ on the rotating assembly
