M177 NANOSLIDE Bore Coating: What It Is and Why It Matters for Tuning
What Is NANOSLIDE and Why Does AMG Use It on the M177? Every AMG 4.0-litre V8 — from the C63 S to the GT R — relies on a twin-wire arc-spray (TWAS) bore coating that Mercedes-Benz brands NANOSLIDE. Instead of pressed-in iron liners, the M177 block receives an ultra-thin iron-carbon layer sprayed directly onto its aluminium cylinder walls. The result is a lighter block, lower friction, and a bore surface that laughs at heat. If you are planning a Stage 2 or Stage 3 build on any M177-powered AMG, understanding this technology is non-negotiable. It defines the ceiling of what...
M177 LS1 vs LS2: Every Difference Between AMG's 4.0L V8 Engines

M177 vs M178 — What's the Difference Between AMG's 4.0L Twin-Turbo V8 Engines?
Mercedes-AMG uses two versions of its hand-built 4.0-litre twin-turbo V8: the M177 and the M178. They share the same bore, stroke, and hot-inside-V turbo layout — but they are not the same engine and they are not interchangeable. If you are ordering an engine build, turbo kit, or any internal component, you need to know which one you have. This guide explains the differences.

M177 Short Block Build — Forged 4.0L Twin-Turbo V8 Bottom End for C63, E63 & GT63 AMG
The M177 short block is the foundation of every big-power AMG 4.0L build. When you are pushing past 700–800 HP on the twin-turbo V8, the factory cast pistons and powder-metal rods become the limiting factor. Our M177 forged short block replaces them with a fully balanced, blueprinted bottom end built for 1,500 HP+ — assembled in-house at YPG Motorsport in Kuwait. What Is an M177 Short Block? A short block is the engine's bottom end: block, crankshaft, connecting rods, pistons, bearings, and internal seals. It does not include cylinder heads, turbochargers, intake, exhaust manifolds, or accessories. You supply and install...
M177 Crate Engine Build — Complete 4.0L Twin-Turbo V8 Long Block for C63, E63 & GT63 AMG
The Mercedes-AMG M177 is the workhorse of AMG's modern lineup — a 3,982 cc twin-turbo V8 with the now-legendary hot-inside-V turbo layout. It powers the C63 AMG (W205), E63 AMG (W213), AMG GT 63, GLC63, GLE63, and more. At YPG Motorsport, we build complete M177 crate engines with forged internals, race-spec tolerances, and the hardware to support 1,500 HP+ with upgraded turbochargers. What Is an M177 Crate Engine? A crate engine — also known as a long block — is a fully assembled engine ready to install. Our M177 crate engines include the complete rotating assembly (forged crankshaft, forged H-beam...
