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 L13L16/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 .
Z16 The Z16 was available in the basic spec Nissan
Navara 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. Applications:
D21 1987- Nissan Navara 910 Nissan Bluebird
FB22 Nissan Atlas 1978.10-1981.06 Nissan VioletAuster/Datsun
160J E23, E24 1980-1990 Nissan Urvan
Z18 The Z18 is an 1.8 L 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 at 6,000 rpm with a twin-barrel carburettor
as fitted in 1980. An export version was rated 77 PS at 5,600 rpm in the Datsun 180K, with
power increasing to 86 PS in the Bluebird and 90–92 PS in twin-carb form, as fitted
to the Bluebird SSS and the export market Silvia.

Nissan VioletStanza/Datsun 180J Z18E
The Z18E is a 1.8 L 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 at 6,200 rpm
in 1980. Applications:
Nissan Bluebird 910 Nissan Skyline 1800TI
Nissan Skyline 1800TI Z18ET
The Z18ET is a 1.8 L 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.
Applications: 1979-1983 Nissan Silvia S110
1979-1986 Datsun Bluebird 910 Z20S
The Z20S is a 2.0 L 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.
Applications: 1979-1981 Datsun 510
1981-1984 Datsun 720 Nissan Cabstar
1980-1986 Nissan/Datsun CaravanNissan Homy E23
1986-1997 Nissan CaravanHomy E24 1979.10-1980.11 Nissan Laurel C230
1980.11-1984.10 Nissan Laurel C31 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.
Z20E 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. 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.
Applications: 1979-1981 Datsun 200SX
1985-1988 Nissan Pickup D21 Z22S
The Z22S is a 2.2 L four-cylinder engine produced from 1980 through early 1983. Bore
and stroke are 87.0 and 92.0 mm. It produces 86 hp SAE as fitted to the US-market Datsun
720. Applications:
1981-1983 Datsun 720 Z22E
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. Applications:
1981-1983 Datsun 200SX Z24
The Z24 is a 2.4 L inline-four produced from 1983 through August 1989. A throttle-body
fuel injected version was also produced, beginning in April 1985.
Applications: 1983.5-1986 Nissan/Datsun 720
1985.5-1986 Nissan/Datsun 720 1986-1990 Nissan Hardbody Truck
1986-1990 Nissan Pathfinder 1987-1990 Nissan Vanette/Nomad
various Forklift applications Z24 versions in gas and LPG
Note: All gasolene Z20, Z22 and Z24 engines were known as NAPS-Z, NAPZ motors had dual
sparkplugs 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 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.
