Script error: No such module "Distinguish". Template:More references Template:Infobox automobile engine 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 Template:Convert 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.

Flat-2

In 1956, Prince developed a flat-2 engine, the FG2D, for their DPSK (later CPSK) concept car. It displaced 601 cc and produced Template:Convert. The engine suffered excessive vibration and noise issues and was replaced with the FG4C engine.[1]

Flat-4

Prince developed the FG4C, a flat-four displacing 599 cc and producing Template:Convert, as a replacement for the FG2D. The FG4C was used in the 1957 CPSK concept.[1]

G-1

The Prince G-1 was the improved GA-4, and was rated at 1.5 L, but displaced Template:Convert thanks to an entirely different Template:Convert bore and stroke. This undersquare arrangement was similar to the designs Nissan licensed from Austin Motor Company, though this is probably coincidental. This engine was also an OHV design and power output was similar to the Nissan G at Template:Convert and Template:Convert.

Applications:

G-2

The G-2 is a Template:Convert version used by Prince. Bore and stroke were square at Template:Convert, and output was Template:Convert and Template:Convert with a 2 barrel carburetor. It was an improved version of the GB-4 and was introduced in 1962 and was installed in the S40 series Prince Gloria as well as the Clipper and Super Miler commercial vehicles. The G-2 was an OHV design.

Applications:

G-15

The SOHC G-15 was a Template:Convert engine produced in 1967 for the Skyline. Bore and stroke was Template:Convert. With a 2 barrel carburetor equipped, the engine produced Template:Convert and Template:Convert. With a crossflow cylinder head, a V-shaped canted valve arrangement and a multi-spherical combustion chamber design, the G-15 was the most technologically advanced Japanese car engine of its day, eclipsing even Nissan's L series engine in their design. The Nissan G engine was not related to the Prince engine; the Nissan version was OHV and slightly smaller displacement. The G-15 was discontinued in 1972 when the C110 Skyline was introduced.

Applications:

G-16

Template:Convert inside diameter x stroke: Template:Convert mmin, SOHC

The G-18 was de-stroked to Template:Convert to form the G-16. Adapting the engine to more stringent US emissions was deemed too expensive, and it was replaced by the Nissan L16 engine in 1975.

Applications:

G-18

The G-18 was a Template:Convert. Its Template:Convert bore was the largest in the range (except for the G20 mentioned in the next paragraph), and the Template:Convert stroke gave it good oversquare dimensions. It was an SOHC cross flow cylinder head design like the G-15 and produced Template:Convert and Template:Convert.

This engine was discontinued in 1975 due to tightening emission regulations and replaced with the L18.

Applications:

G-20

Twin SU carburetor regular gasoline

Twin SU carburetor high octane gasoline

This engine was only used in the 1968-1975 C30 & C130 Laurel, and was discontinued in 1975 due to tightening emission regulations.

Straight-6

Prince used a straight-6 version of the G family in their famous Skyline cars. All of the Prince straight-6 engines used single overhead cam heads. Engine displacement was kept below 2000cc to limit the amount of Road tax to be paid yearly in addition to other Japanese Government mandated expenses.

G-7

Prince G-7 engine

The G-7 is a straight-6 version displacing Template:Convert. 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 Template:Convert and power output varied with the carburetor equipped. Plain versions featured a 2 barrel carb and 8.8:1 for Template:Convert and Template:Convert, while the 1965 Skyline GT-B used 3 twin-barrel Weber carburetors and 9.3:1 compression for Template:Convert and Template:Convert. It was influenced by the Mercedes-Benz M180 straight six engine.[2] The intake and exhaust manifolds are on the left side of the engine because Japanese drivers sit on the right side and the steering column would interfere, while the Mercedes-Benz engine places the intake and exhaust on the right side due to left hand driving conditions.

Applications:

G7B-R

Template:Convert inside diameter x stroke: Template:Convert

An improvement on the G7 using a cross-flow cylinder head and was converted into racing use during 1965 - 1966 in the S54 Skyline GT used for racing. Was not commercially available.

Racing engine used in the Prince R380 and Nissan R380-II, based on the G7 engine.[4] It used 4 valves per cylinders and DOHC, used 3 Weber carburetors model 42DCOE-18, producing a claimed Template:Convert for the R380 and Template:Convert for the R380-II.[3] The GR-8 used in the R380-III featured mechanical fuel injection.[3]

The Nissan S20 engine was derived from the GR-8.[5]

G-11

The G-11 is another straight-6 OHC version, displacing Template:Convert. Bore was up to Template:Convert like the G-2 4-cylinder, while stroke remained at Template:Convert as on the G-7. Power output with a 4 barrel carburetor was Template:Convert with Template:Convert of torque.

Applications:
