The Nissan GA13DS is an inline 1.3 liter (1,295 cc; 79.02 cu-in) four-cylinder, four-stroke cycle carbureted gasoline engine from Nissan GA-family, utilizing cast iron for the block and aluminum alloy for the cylinder head.
It has a double overhead camshaft driving sixteen valves (two valves per cylinder) and carburetor. A 71 mm (2.8 in) cylinder bore and 81.8 mm (3.22 in) piston stroke give the engine a total of 1.3 L of displacement. Compression ratio rating is 9.5:1.
The Nissan GA13DS produces 79 PS (58 kW, 78 HP) at 6,000 rpm of horsepower and 104 Nm (10.6 kg⋅m, 76.7 lb·ft) at 3,600 rpm of torque.
The breakdown of the engine code is as follows:
- GA – Engine Family
- 14 – 1.3 Liter Displacement
- D – DOHC (Dual Overhead Camshafts)
- S – Carburetor

Cylinder head
The engine has an aluminum cylinder head with two chain-driven overhead camshafts. Intake valves are 26 mm in diameter, intake duration is 222°, and the exhaust valves are 21 mm in diameter, exhaust duration is 222°. The GA13DS does not have hydraulic lifters, so special shims are used to adjust the valve clearance.

Problems and malfunctions
The engine has two timing chains, their service life is about 150,000 miles of mileage (200,000-250,000 km). The valve clearance needs to be adjusted every 30,000 miles of mileage (40,000-50,000 km). The GA13DS motor life expectancy is 200,000 miles of mileage (300,000 km) or more.

Valve clearance adjustment data
Calculate the thickness of new adjusting shim so valve clearance comes within specified values.
R = Thickness of removed shim
N = Thickness of new shim
M = Measured valve clearance
Intake:
N = R + [M – 0.37 mm (0.0146 in)]
Exhaust:
N = R + [M – 0.40 mm (0.0157 in)]
Shims are available in 50 sizes from 2.00 mm (0.0787 in) to 2.98 mm (0.1173 in), in steps of 0.02 mm (0.0008 in).
Example (intake valve):
R = 2.10 mm
M = 0.52 mm
N = 2.10 + (0.52 – 0.37) = 2.25 mm, so we need a shim with code 225 or TS225.
