The Nissan Z engine is a series of automobile and light truck engines that was engineered by Nissan Machinery, manufactured by the Nissan Motor Company from 1979 through August 1989. All Z engines had 4 cylinders, a total of 8 valves and a single overhead camshaft (SOHC). Displacements ranged from ranged from 1.6 L to 2.4 L.The Z series' engine blocks were nearly identical to those of the earlier L Series with the exception of the Z24. While the Z16 and Z18 engines had a deck height similar to the earlier L13/L14/L16/L18 variants, the Z24 had a taller deck height to accommodate a longer stroke. The most notable difference between the Z-series engine and its predecessor was the introduction of a new 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 NA and KA engines which, along with the smaller CA series, replaced the Z series .
The Z16 made its first appearance in 1978 in a new base-model version of the Nissan Navara (D21), which had debuted the previous year with the then-new Z18. Offered only in selected overseas markets, this version of the engine came with a single downdraft carburetor. Later it was also seen in a few low-end model Datsun Bluebird 910s for the Japanese domestic market and some Nissan commercial vehicles in a single-plug configuration.

The Z16E is an EFI version of Z16S adopted the Nissan EGI. Released at the same time as the Z16S, it is mainly used in intermediate grade. It has almost the same internal structure as Z16S, but some of the improvement in output have been made.

The Z18 debuted in 1977, the first model of the Z-type engine to be released. Displacing 1.8 L (1,770 cc) with a bore of 85.0 mm and stroke of 78.0 mm, it is essentially an older L18 type series four-cylinder with the new cross-flow cylinder head. A 1980 twin-carburetor version produced 105 PS (77 kW) @ 6,000 rpm ( SAE ). Export specification is 77 PS (56.6 kW) those of Datsun · 180K (C210 type Skyline) @ 5,600 rpm ( DIN / net [Note 2] ), is 86 PS (63.3 kW) those of 910-series Bluebird, twin carburetor specifications 910 Bluebird SSS and Sylvia for export was 90-92PS (66.2-67.7 kW).
