The CA engine is a series of 1.6 to 2.0 L (1,598 to 1,974 cc) Inline-4 piston engines from Nissan. It is designed for a wide variety of smaller Nissan vehicles to replace the Z engine and some smaller, four-cylinder L series engines. The "CA" stands for Clean Air, due to the installation of Nissan emission reducing technology, called NAPS-X.
The CA is an iron block, aluminum head design with a timing belt, cheaper to make than the timing chain setup on the Z and L engines. Earlier versions featured SOHC and eight valves. The new CA block design was a scaled-up E series block with timing shaft and other ancillaries removed. The oil pump is fitted directly onto the crank nose and the distributor is driven by the end of the camshaft. Like the E series and the A block from which the E was derived, Nissan used a taller block for the largest stroked 2.0-litre engine. The CA was designed to be compact and light, with a CA16 requiring only 195 litres (52 US gal; 43 imp gal) of space (compared to 280 litres (74 US gal; 62 imp gal) for the earlier Z16), while weighing 23% less at 115 kg (254 lb).
Later versions featured DOHC with 16 valves for increased efficiency at high engine speeds and a smoother power delivery. The hydraulic lifters are interchangeable between all DOHC RB and VG series engines excepting those with solid lifters. The Nissan CA would also be developed into a diesel engine, known as the CD, which replaced the four-cylinder LD series.
Production of the CA series ceased in 1994. The engine was deemed too expensive to produce due to its cast-iron block, while it also no longer met the ever-changing Japanese emission standards emerging at the time. The 1.8 L and 2.0 L versions were replaced by the all-aluminium SR series as Nissan's primary four-cylinder engine, while the smaller 1.6 L version was replaced by the GA series. Engines for the low volume European markets, such as the 200SX, were supplied by the overstock between Japanese and Australian markets.




CA16


The CA16 series of engines is a 1.6 L (1,598 cc) engine produced from 1985 through 1990. Bore and stroke is 78 mm × 83.6 mm (3.07 in × 3.29 in) and it was built either with carburetors or fuel injection.

The CA16DE is a 1.6 L (1,598 cc) engine produced from 1987 through 1989. It produces 122 hp (91 kW; 124 PS) at 6400 rpm and 137 N⋅m (101 lb⋅ft) at 5200 rpm. Bore and stroke is 78 mm × 83.6 mm (3.07 in × 3.29 in). It was a 16-valve DOHC engine with multi-port fuel injection, for front wheel drive use. North American versions used Nissan's NICS (Nissan Induction Control System), which opened up the secondary intake ports to each cylinder via a butterfly valve in each port. Activated at 3,900 rpm, this improved flow and performance resultingly. Additionally, on activation of the secondaries under a heavy load the fuel injection also went from sequential mode to simultaneous-pulse mode. These features were also found on North American CA18DE engines.

= CA18DET

=

The 1.8 L (1,809 cc) CA18DET was the last version of the CA engine to be released, manufactured from 1985 to 1994. It is a turbocharged version of the CA18DE, producing 124 kW (169 PS; 166 hp) and 228 N⋅m (168 lb⋅ft). It has a brand new DOHC aluminum head with 16 valves. The turbocharger was also upgraded to a Garrett T25 (.48 A/R) unit for increased flow capacity, and as such, was fitted with an intercooler to help prevent the onset of pre-ignition and/or detonation. Fuel was delivered via Multiport Fuel Injection. Bore and stroke is 83 mm × 83.6 mm (3.27 in × 3.29 in). An electronically controlled fuel injection system was used with 370 cc (23 cu in) (flow capacity) injectors.
There were 2 versions of the CA18DET available, yet only one was produced for Japan. The late model Japanese CA18DETs received 8 port (low port) heads, with butterfly actuated auxiliary ports in the lower intake manifold which corresponded with 8 ports in the head.
Below c. 3,800 rpm, only one set (4 ports open, 1 per cylinder) of long, narrow ports would be open, accelerating the intake charge to the cylinder. This allowed for quick spool and good low-end tractability. At the 3800 rpm change over, not only would the ECCS shift into batch fire (as opposed to sequential) fuel injection, but it also opened the second set of short, wide ports (8 ports open, 2 per cylinder) which assisted in high RPM flow.
This engine is known for stronger torque characteristics, as well as faster spool at lower RPMs. However, due to displacement-based taxation and cost of emissions testing in Europe, the CA18DET was sold as the only available engine in the S13 chassis 200SX (Euro model) until replaced by the S14 in 1994. The Euro motors received the 4 port (high port) head and intake manifold, as well as revised ECCS ("Electronic Concentrated Control System") parameters.
It was used in the following vehicles:

1987-1988 Silvia S12 RS-X
1987-1989 Silvia S12 Grand Prix final edition in Europe
1988-mid 1990 Nissan Silvia/180SX S13 (Japanese market)
1987-1989 Nissan Bluebird RNU12 SSS ATTESA Limited (Japanese Market)
1989-1994 Nissan 200SX RS13-U Europe.
1985-1990 Nissan Auster "1.8Xtt" and "Euroform Twincam Turbo"




CA20


The CA20 is a series of SOHC 2.0 L (1,974 cc) engine produced from 1982 through 1991 (possibly longer for the CA20P). Bore and stroke is 84.5 mm × 88 mm (3.33 in × 3.46 in).




= CA20P

=

The CA20P is a carbureted, single overhead cam designed to run on LPG. It came in two claimed different power outputs, initially 90 PS (66 kW; 89 hp) JIS gross at 5,600 rpm and later 82 PS (60 kW; 81 hp) JIS net at 4,800 rpm. The respective torque figures are 15.5 kg⋅m (152 N⋅m; 112 lb⋅ft) at 2,800 rpm and 15.2 kg⋅m (149 N⋅m; 110 lb⋅ft) at 2,000 rpm. This engine was usually installed in professional cars and was not regularly available to private buyers. It was replaced by the NA20P engine in mid-1991.

= CA20DE/CA20DET/CA20ET

=
There was never a factory-produced twin-cam 2.0 L CA engine, nor there was a turbo version. However, the blocks are similar, and it is possible to fit the DOHC CA18DE/CA18DET twin-cam head into the SOHC CA20 block. However, the DOHC/SOHC manifolds are different and the timing pulley/belts are not compatible. Despite this, however, several examples of a CA20DET engine have been built.




Stroker kits


Tomei and JUN of Japan produced 2–litre stroker kits for the CA18. Also companies like Norris Designs and Spool Imports produces CA20 stroker kits as well as a CA20 engine.
