M177 CAMTRONIC Cylinder Deactivation: How It Works and Tuning Implications
What Is CAMTRONIC and How Does It Work on the M177? Every M177-powered AMG — the C63, E63, AMG GT, GT 63, and GLC 63 — uses a cylinder-deactivation system Mercedes-Benz calls CAMTRONIC. Under light loads, four of the engine’s eight cylinders shut down to cut fuel consumption. The moment you press the throttle, all eight fire again in milliseconds. For tuners, CAMTRONIC matters because it directly affects camshaft behaviour, ECU calibration tables, and exhaust-gas temperature management. Whether you are running a Stage 1 ECU flash or building a 900 HP monster, you need to understand what this system does...
AMG Engine Build Cost Guide 2026 — What Does a Forged M156, M177, or M178 Build Cost?
Building a forged AMG engine is a significant investment — and one of the best decisions you can make for a high-power build. But what does it actually cost in 2026? This guide breaks down the market ranges for AMG engine builds so you can budget realistically, understand what drives the price, and avoid surprises. Market Price Ranges (2026) Pricing varies by engine code, build level, and specification. These are general market ranges — not specific YPG pricing. Contact us for an exact quote on your build.

M178 CNC-Ported Heads — Flow-Matched Cylinder Heads for AMG GT Dry-Sump 4.0L V8
The AMG GT platform demands heads that can flow under sustained high-RPM, high-boost, high-heat conditions — lap after lap. Our M178 CNC-ported heads are flow-bench developed for the dry-sump 4.0L V8, assembled with upgraded valvetrain, and sold as a matched pair. Built at YPG Motorsport in Kuwait, shipped worldwide. What Are CNC-Ported Heads? CNC porting reshapes the intake and exhaust ports using computer-controlled machining to our flow-bench program. Every port is cut to identical runner volumes and matched flow rates across all eight cylinders. On a twin-turbo engine like the M178, ported heads reduce pumping losses, improve turbo spool, and...
M177 CNC-Ported Heads — Flow-Matched Cylinder Heads for 4.0L AMG Twin-Turbo V8
On a turbocharged engine, the heads are not just an airflow component — they are a thermal management system. Our M177 CNC-ported heads are flow-bench developed and assembled with upgraded valvetrain to reduce pumping losses, improve spool, and let your turbos push more air through the combustion chambers efficiently. Built at YPG Motorsport in Kuwait, sold as a pair. What Are CNC-Ported Heads? CNC porting reshapes the intake and exhaust ports using computer-controlled machining. Every port is cut to our flow-bench program — matched runner volumes, identical flow rates across all eight cylinders. On a twin-turbo engine like the M177,...
M156 CNC-Ported Heads — Flow-Matched Cylinder Heads for 6.2L AMG V8
The factory M156 cylinder heads flow well from the factory — but "well" is not "race-ready." Our M156 CNC-ported heads are flow-bench developed, precision-machined, and assembled with upgraded valvetrain to unlock the airflow your forged bottom end needs. Built in-house at YPG Motorsport in Kuwait, sold as a pair, and shipped worldwide. What Are CNC-Ported Heads? CNC porting uses computer-controlled machining to reshape the intake and exhaust ports inside your cylinder heads. Every port is cut to our proven flow-bench program — identical runner volumes, matched flow rates across all eight cylinders. The result is more air in, more exhaust...
