Nissan E engine

The Nissan E engine name covers two different families. The first was an older OHV inline-4 used from the late 1950s into the 1960s. The second is a later SOHC inline-4, produced from 1.0 to 1.6 liters (988 to 1,597 cc) between 1981 and 1988, and then replaced by the GA series.

Design and specs
- Configuration: inline-4 engines
- Block and head: cast-iron block with an aluminum head
- Valvetrain: originally OHV, later SOHC
- Displacement options: 1.0 L (E10), 1.3 L (E13), 1.5 L (E15), 1.6 L (E16)
- Bore and stroke (examples): E10 73 mm × 59 mm; E13 76 × 70; E15 76 × 82; E16 76 × 88
- Compression: 8.3:1
- Turbocharging: available on E15 and E16 in certain versions
- Fuel system: Solex carburetor or throttle-body fuel injection
- Fuel type: gasoline
- Cooling: water-cooled
- Power range: roughly 48 to 115 PS (35–85 kW; 47–113 hp)
- Torque range: roughly 82.3–91.2 N·m (60.7–67.3 lb-ft)

Variants and what they did
- E10: 1.0 L engine (73 × 59). Around 50 PS (varies by market); about 75 N·m of torque in early form. Notable for its over-square bore/stroke (large bore, short stroke), which helped high-rev performance.
- E13: 1.3 L (76 × 70). About 60 PS in the base version, with higher output in some markets (67 PS in twin-carb form; up to around 75 PS in Japanese market).
- E15: 1.5 L (76 × 82). Several versions existed: single carb, twin-carb E15S, fuel-injected E15E, and turbocharged E15ET (turbo version discontinued in 1987). Turbos boosted power significantly in suitable markets.
- E16: 1.6 L (76 × 88). North American carb version produced about 69–70 hp; injected version about 71 hp. European E16S with no catalytic converter produced around 84 PS. A turbo variant was used in some markets (about 93 hp in turbo setup) with a modified air system.

Applications
- The E-series engines were first used in the N10 Pulsar/Cherry and later in the B11 Sentra/Sunny models.
- They were gradually replaced by the GA-series by 1988–1989, though some markets kept using E-series engines into the late 1980s and beyond (for example, Malaysia’s B11 Sunny 130Y used E-series engines into the mid-1990s).

Extra notes
- The E-series engine line evolved from Nissan’s earlier designs, with the switch from OHV to SOHC reflecting a move to lighter heads and better airflow.
- The E15ET turbo and the E16 turbo adaptations show how Nissan used turbocharging to boost power in smaller displacements during the era.
