context_page_description: The Prince G-series engine was the company's only straight-four and straight-six engines which began production in 1955. A number of variations were made, with both OHV and OHC heads. A diesel four-cylinder with 1.9 L was also built, called the D-6. The G series was used in the Skyline, the Laurel, and the Gloria from the 1950s to the early 1970s.
  Note that, prior to its merger with Prince, Nissan also made a G series of engines. These are unrelated engines and are documented at the Nissan G engine page.

context_section_description: The G-7 is a straight-6 version displacing 2.0 L; 121.3 cu in (1,988 cc). It was the engine of the GT-model Prince Skylines and was an OHC engine unlike the mainly-OHV family that spawned it. Bore and stroke were square at 75 mm (2.95 in) and power output varied with the carburetor equipped. Plain versions featured a 2 barrel carb and 8.8:1 for 106 hp (79 kW; 107 PS) and 16 kg⋅m (157 N⋅m; 116 lb⋅ft), while the 1965 Skyline GT-B used 3 twin-barrel Weber carburetors and 9.3:1 compression for 127 hp (95 kW; 129 PS) and 17 kg⋅m (167 N⋅m; 123 lb⋅ft).
