The MK2A Zuisei engine was a 14-cylinder, supercharged, air-cooled two-row radial engine with a 140 mm (5.5 in) bore and 130 mm (5.12 in) stroke for a displacement of 28L (1,710ci) and a nominal power rating of 805 kW (1080 hp) for takeoff and 787 kW (1055 hp)

Mitsubishi used the standard designation system to identify this engine while it was under development. The MK2 designation starts with the Manufacturer's assigned identification letter, in this case, "M" for Mitsubishi, followed by a letter that identifies the engine arrangement, in this case "K"

was a 14-cylinder, supercharged, air-cooled, two-row radial engine used in a variety of early World War II Japanese aircraft. It was one of the smallest 14-cyl. engines in the world and the smallest diameter Japanese engine. The Mitsubishi model designation for this engine was

Mitsubishi also had a custom to name its engines with a short two syllable name that references objects found in the sky. The naming sequence started with this engine, the MK2 Zuisei "Holy star", and was followed in order by the MK4 Kinsei "Venus" and the MK8 Kasei "Mars".
