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 60&ordm; 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.

[[Image:6G71_Supercharged.jpg|thumb|left|200px|Supercharged 2.0L V6 6G71]]The 6G71 is the rarest model of the 6G7x family, being a 2.0L single overhead cam V6 with 2 valves per cylinder. It displaces 1998cc with a 74.7mm bore and 76mm stroke.
 +
 
 +
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.

Three variants of the engine were produced:
