2005 Porsche 911 GT3 Cup Engine – 3.6L Mezger Flat-Six

The 2005 Porsche 911 GT3 Cup engine is a true motorsport-bred powerplant, developed for Porsche’s factory racing program and derived from the legendary Mezger architecture. This 3.6-liter M96/76 flat-six is renowned for its exceptional durability, high-revving performance, and race-proven reliability, making it one of the most desirable engines in Porsche’s modern history.

Built with four-valve cylinder heads and VarioCam variable valve timing, the engine delivers strong mid-range response and sustained high-RPM performance. A dry-sump lubrication system ensures consistent oil pressure under extreme cornering and track conditions, while titanium connecting rods reduce rotating mass and enhance throttle response.

Engine management is handled by a dedicated ECU, allowing precise fuel and ignition control optimized for competition use. Designed specifically for the 911 GT3 Cup, this engine is ideal for race cars, track builds, or collectors seeking authentic Porsche motorsport hardware.
