The Nissan QG13DE is a 1.3 liter (1,295 cc, 79.0 cu·in) straight-four 4-stroke natural aspirated gasoline engine from Nissan QG-family.
The QG13DE motor has a cast-iron cylinder block and aluminum alloy cylinder head with two overhead camshafts (DOHC). The engine uses a multi-point fuel injection system; an electronic ignition system with individual ignition coil for each cylinder and ERG system.
A 71.0 mm (2.8 in) cylinder bore and 81.8 mm (3.22 in) piston stroke give the QG13DE engine a total of 1,295 cc of displacement. The compression ratio rating is 10.0:1. The Nissan QG13DE engine produced from 87 PS (64 kW; 86 HP) at 6,000 rpm to 90 PS (66 kW; 89 HP) at 6,000 rpm of maximum output power and from 113 N·m (11.5 kg·m, 83.3 ft·lb) at 4,400 rpm to 120 N·m (12.2 kg·m, 88.4 ft·lb) at 4,400 rpm of peak torque.
The breakdown of the engine code is as follows:
- QG – Engine Family
- 13 – 1.3 Liter Displacement
- D – DOHC (Dual Overhead Camshafts)
- E – Multi Point Fuel Injection

Cylinder head
The engine has an aluminum cylinder head with two chain-driven overhead single-piece cast camshafts and sixteen valves (four per cylinder). The QG13DE has a single timing chain. Intake valves are 26.0 mm (1.04 in) in diameter and the exhaust valves are 21.5 mm (0.85).
The QG13DE does not have hydraulic lifters, so special shims are used to adjust the valve clearance.

Valve clearance adjustment data
Calculate the thickness of the 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.
| For adjusting | For checking | ||
| Hot | Cold* | Hot | |
| Intake | 0.32-0.40 mm (0.013-0.016 in) | 0.25-0.33 mm (0.010-0.013 in) | 0.21-0.49 mm (0.008-0.019 in) |
| Exhaust | 0.37-0.45 mm (0.015-0.018 in) | 0.32-0.40 mm (0.013-0.016 in) | 0.30-0.58 mm (0.012-0.023 in) |
*: At a temperature of approximately 20°C (68°F)
Whenever valve clearances are adjusted to cold specifications, check that the clearances satisfy hot specifications and adjust again if necessary.
