Prince G engine

March 09, 2024

Not to be confused with Nissan G 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 1.9 L (1,862 cc) 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.

Flat-2 edit

In 1956, Prince developed a flat-2 engine, the FG2D, for their DPSK (later CPSK) concept car. It displaced 601 cc and produced 24 hp (24 PS). The engine suffered excessive vibration and noise issues and was replaced with the FG4C engine.[1]

Flat-4 edit

Prince developed the FG4C, a flat-four displacing 599 cc and producing 38 hp (39 PS), as a replacement for the FG2D. The FG4C was used in the 1957 CPSK concept.[1]

G-1 edit

 
Prince G-1 engine of Nissan Prince Skyline 1500 Van Deluxe V51B

The Prince G-1 was the improved GA-4, and was rated at 1.5 L, but displaced 1.5 L; 90.6 cu in (1,484 cc) thanks to an entirely different 75 by 84 mm (2.95 by 3.31 in) 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 73 hp (54 kW; 74 PS) and 12 kg⋅m (118 N⋅m; 87 lb⋅ft).

Applications:

G-2 edit

The G-2 is a 1.9 L; 113.6 cu in (1,862 cc) version used by Prince. Bore and stroke were square at 84 mm (3.31 in), and output was 96 hp (72 kW; 97 PS) and 15.7 kg⋅m (154 N⋅m; 114 lb⋅ft) 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 edit

The SOHC G-15 was a 1.5 L; 90.5 cu in (1,483 cc) engine produced in 1967 for the Skyline. Bore and stroke was 82 mm × 70 mm (3.23 in × 2.76 in). With a 2 barrel carburetor equipped, the engine produced 94 hp (70 kW; 95 PS) and 13.3 kg⋅m (130 N⋅m; 96 lb⋅ft). 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.

Applications:

G-16 edit

1.6 L (1,593 cc) inside diameter x stroke: 85 mm × 70.2 mm (3.35 in × 2.76 in) mmin, SOHC

  • maximum output (gross) 100 PS (74 kW; 99 bhp) @ 6000 rpm
  • Maximum torque (gross) 13.8 kg⋅m (135 N⋅m; 100 lb⋅ft) @ 4000 rpm

The G-15 was bored out 3 mm (0.12 in) to form the G-16. Adapting the engine to more stringent US emissions was deemed too expensive, and it was replaced by the L16 engine in 1975.

Applications:

G-18 edit

The G-18 was a 1.8 L; 110.8 cu in (1,815 cc). Its 85 mm (3.35 in) bore was the largest in the range (except for the G20 mentioned in the next paragraph), and the 80 mm (3.15 in) stroke gave it good oversquare dimensions. It was an SOHC cross flow cylinder head design like the G-15 and produced 105 hp (78 kW; 106 PS) and 15.9 kg⋅m (156 N⋅m; 115 lb⋅ft).

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

Applications:

G-20 edit

2.0 L (1,990 cc) inside diameter x stroke: 89 mm × 80 mm (3.50 in × 3.15 in), SOHC

  • compression ratio 8.3:1
  • maximum output (gross) 120 PS (88 kW; 118 bhp) @ 5800 rpm
  • maximum torque (gross) 17 kg⋅m (167 N⋅m; 123 lb⋅ft) @ 3600 rpm

Twin SU carburetor high octane gasoline

  • compression ratio 9.7:1
  • maximum output (gross) 125 PS (92 kW; 123 bhp) @ 5800 rpm
  • maximum torque (gross) 17.2 kg⋅m (169 N⋅m; 124 lb⋅ft) @ 3600 rpm

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

Straight-6 edit

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 edit

 
Prince G-7 engine

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). 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 edit

2.0 L (1,988 cc) inside diameter x stroke: 75 mm × 75 mm (2.95 in × 2.95 in)

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.

GR-8 edit

  • maximum output (gross) more than 200 PS (147 kW; 197 bhp) @ 8400 rpm[4]

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 200 hp (149 kW; 203 PS) for the R380 and 220 hp (164 kW; 223 PS) 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 edit

The G-11 is another straight-6 OHC version, displacing 2.5 L; 152.2 cu in (2,494 cc). Bore was up to 84 mm (3.31 in) like the G-2 4-cylinder, while stroke remained at 75 mm (2.95 in) as on the G-7. Power output with a 4 barrel carburetor was 134 hp (100 kW; 136 PS) with 19.9 kg⋅m (195 N⋅m; 144 lb⋅ft) of torque.
