The Nissan HR10DE is a 1.0 l (999 cc, 60.96 cu-in) straight three, four-stroke naturally aspirated internal combustion gasoline engine from Nissan HR family.
The HR10DE has an aluminum engine block with four main bearings and aluminum DOHC (dual overhead camshaft) cylinder head with four valves per cylinder (12 valves in total). The HR10DE is a Flex-Fuel engine and can use gasoline or ethanol.
It has a 78.0 mm (3.07 in) cylinder bore and 69.7 mm (2.74 in) piston stroke. Compression ratio rating is 11.2:1. The Nissan HR10DE produced 77 PS (56.6 kW; 75.9 HP) of horsepower and 98 Nm (10 kg·m; 72.3 ft·lb) of torque.
The breakdown of the engine code is as follows:
- HR – Engine Family
- 10 – 1.0 Liter Displacement
- D – DOHC (Dual Overhead Camshafts)
- E – Electronic Port Fuel Injection

Valve clearance adjustment data
Calculate the thickness of new adjusting valve lifter so valve clearance comes within specified values.
R = Thickness of removed valve lifter
N = Thickness of new valve lifter
M = Measured valve clearance
Intake:
N = R + [M – 0.30 mm (0.012 in)]
Exhaust:
N = R + [M – 0.33 mm (0.013 in)]
Valve lifters are available in 26 sizes range from 3.00 mm (0.1181 in) to 3.50 mm (0.1378 in), in steps of 0.02 mm (0.0008 in).
Example (intake valve):
R = 3.10 mm
M = 0.52 mm
N = 3.10 + (0.52 – 0.30) = 3.32 mm, so we need a valve lifter with identification mark 332.
| Cold | Hot | |
| Intake | 0.26-0.34 mm (0.010-0.013 in) | 0.304-0.416 mm (0.012-0.016 in) |
| Exhaust | 0.29-0.37 mm (0.011-0.015 in) | 0.308-0.432 mm (0.012-0.017 in) |
