The Nissan Z series of automobile engines ranged from 1.6 L to 2.4 L and were produced from 1979 through August 1989. The Z series engines retained a nearly identical block to the earlier L Series with the exception of the Z24 which utilized a taller deck height to accommodate an increased stroke. The Z16 and Z18 engines used a shorter block similar to the earlier L13/L14/L16/L18 variants. All Z engines were SOHC. The most notable feature of the Z-series engine was the change from the L series head, to a crossflow cylinder head which reduced emissions by moving the intake ports to the right side of the engine opposite the exhaust ports. This change allows the exhaust port velocity to more effectively scavenge the cylinder and reduce reversion pulses to enhance induction. The Z-series evolved into the Nissan NA,and KA engines which along with the smaller CA series replaced the Z series .
The Z16 was available in the basic spec Nissan Navara (D21) in certain markets. It is an inline-four with SOHC, eight valves and a single downdraft carburettor. It was also seen in a few low-end model Datsun Bluebird 910s for the Japanese domestic market.

The Z18 is an 1.8 L (1,770 cc) straight-four engine with SOHC and eight valves and was essentially a crossflow version of the older L18. Bore and stroke are 85.0 x 78.0 mm. It produces 105 PS (77 kW) (SAE) at 6,000 rpm with a twin-barrel carburettor as fitted in 1980. An export version was rated 77 PS (56.6 kW) (DIN) at 5,600 rpm in the Datsun 180K (C210 Skyline), with power increasing to 86 PS (63.3 kW) in the Bluebird and 90–92 PS (66.2–67.7 kW) in twin-carb form, as fitted to the Bluebird SSS and the export market Silvia.

The Z18E is a 1.8 L (1,770 cc) fuel injected engine produced primarily for the Japanese market. Most specs were the same as for the Z18, but max power increased to 115 PS (85 kW) (SAE) at 6,200 rpm in 1980 (Bluebird, Skyline).
The Z18ET is a 1.8 L (1,770 cc) turbocharged and fuel injected engine first introduced in the 1979 S110 Silvia/Gazelle it was produced primarily for the Japanese market. It produces 135 hp (101 kW).
The Z20S (S denotes carbureted) is a 2.0 L (1,952 cc) engine, with an 85.0 x 86.0 mm bore and stroke, produced from 1979 through 1984. It replaced the L20B using many of the same lower end components.

In the US, the Z20S was only available in the 1980-81 510/A10 and 1984 720pickup w/MPG option.
The Nissan Caravan and Homy with this engine produced a maximum speed of 160 km/h. It was noted for being faster than its competitor Toyota Hiace, primarily because Z20S produced more power than the engines available in the Hiace.
The Z20E is a fuel-injected version of the Z20S engine produced from 1979 through July 1984. It also had longer connecting rods and shorter compression-height pistons than the 1980-81 Z20S. It produces 100 ps (74 kW). The Z20E was not available in the 720 pickup, which only used carburetted versions. The Z20 engine was not available at all in US-spec. 720 pickups nor California-spec. D21 pickups.

The Z22S (carb only) is a 2.2 L (2,188 cc) four-cylinder engine produced from 1980 through early 1983. Bore and stroke are 87.0 and 92.0 mm. It produces 86 hp (64 kW) SAE as fitted to the US-market Datsun 720.
- 1981-1983 Datsun 720
The Z22E is a fuel injected version of the Z22 engine produced from 1981 through 1983, mainly for North America. This engine also has longer connecting rods and shorter compression-height pistons than the carbureted Z22S engine.
The Z24 is a 2.4 L (2,389 cc) inline-four produced from 1983 through August 1989. A throttle-body fuel injected version (Z24i) was also produced, beginning in April 1985.

various Forklift applications Z24 versions in gas and LPG
Note: All gasolene Z20, Z22 and Z24 engines were known as NAPS-Z (NAPZ or NAPS-Z Nissan Anti Performance System), NAPZ motors had dual sparkplugs (2 per cylinder) except the pre-82 versions and latest versions of the Z24i as fitted to the Pathfinder. However all NAPZ engines sold in California reportedly had dual plug heads regardless of the year.
The fuel injected version referenced above was denoted as the Z24i (Throttle Body Fuel Injection) and was first available in the Nissan Model 720 ST pickup during the 1985 model year and was replaced in 1990 by the KA24E engine. Beside the fuel injection, a significant change for the Z24i was the addition of an optical crank angle sensor in the distributor rather than a vacuum advance and ignition module. This allowed the JECS throttle-body injection system to identify cylinder #1 top dead center (TDC).
