| − | + | Mitsubishi's '''6G7x family''' of engines (also known as the Cyclone V6) was Mitsubishi's first V6 engine, introduced to the Japanese market in 1986. The engines have a 60º vee angle, cast iron blocks with aluminum alloy cylinder heads and belt driven camshafts. The engine has seen service in front, rear and all-wheel drive applications. As with the [[Sirius family]] there can be many variants within a single model of engine. | |
As with many other Mitsubishi engine families, the 6G7x was also used in Hyundai and Chrysler vehicles. | As with many other Mitsubishi engine families, the 6G7x was also used in Hyundai and Chrysler vehicles. | ||

| + | |||
| + | The engine was available in normally aspirated versions (some with single-point fuel injection, others with multi-point fuel injection) with a 8.9:1 compression ratio and a supercharged version with a 8.0:1 ratio. | ||
| + | |||
| + | The supercharged engine was transversely mounted in some Japanese Debonair Vs and used a Mikuni DM51 supercharger and water-to-air intercooler. The supercharger was mounted to the front cylinder bank and connected directly to the throttle body. | ||
