What's the Difference Between M177 and M178?
Both are AMG 4.0L twin-turbo V8s sharing the same block architecture and cross-plane crankshaft. The M177 uses wet-sump lubrication — found in the C63, E63, GLC63, and G63. The M178 uses dry-sump lubrication and a lower, rear-mounted engine position — exclusive to the AMG GT family. The dry-sump system allows the engine to sit lower in the chassis, improving center of gravity and enabling sustained high-G cornering without oil starvation.
What's Included
Complete forged long block assembly — heads, block, forged crankshaft, forged connecting rods, forged pistons, and valve train. Ships as a long block, but can be configured with upgraded turbos, manifolds, and accessories depending on your build requirements. Contact YPG Motorsport to spec your build.
Forged Rotating Assembly Specification
Every YPG M178 crate engine is built with the same forged rotating assembly used in our standalone M178 Forged Internals kit. Included:
