Nissan CA engine Overview Production 1982-1991 Layout 1.6L 1.8L 2.0L alloy alloy SOHC & DOHC Combustion Single (CA18ET, CA18DET) system Carburetor (CA16S, CA18S, CA20S) Throttle body fuel injection (CA18i) Multi port fuel injection (CA16DE, CA18DE, CA18ET, CA18DET, CA20E) Water-cooled Chronology Predecessor & Successor (all except CA16) (CA16) The CA engine is a 1.6 L to 2.0 L from designed for a variety of smaller vehicles to replace the and some smaller, four-cylinder series engines. It 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 and eight valves. The new CA block design was a scaled-up 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 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 of space (compared to 280 litres for the earlier ), while weighing 23% less at 115 kg (254 lb).

The engine was called the 'CA' series for Clean Air, due to the installation of Nissan emission reducing technology, called. Later versions featured with 16 valves for increased efficiency at high engine speeds and a smoother power delivery. The hydraulic lifters are interchangeable between all and series engines accepting those with solid lifters. The motor was expensive to produce being cast iron, Production ceased in 1991. The 1.8 L and 2.0 L versions were replaced by the series as the primary Nissan four-cylinder engine, while the smaller 1.6 L was replaced by the. Engines for the low volume American and European markets, were supplied by the overstock between Japanese and Australian markets.

Contents. CA16S The CA16S is a 1.6 L (1598 cc) water cooling serial 4-cylinder OHC engine. It produces 81 PS (60 kW; 80 hp) at 5200 rpm and 123 N⋅m (91 ft⋅lbf) at 3200 rpm.

Applications:. 1989 U11 - 90 PS (66 kW; 89 hp), 13.6 kg⋅m (133 N⋅m; 98 lb⋅ft). 1985-1990 T12/T72. 1986-1990 T12 '1.6Vc', '1.6Mc'. 1986-1990 JDM T12 'Supreme 1.6'.

88 PS (65 kW; 87 hp), double-barrel carburator CA16DE The CA16DE is a 1.6 L (1598 cc) engine produced from 1987 through 1989. It produces 122 hp (91 kW) at 6400 rpm and 137 N⋅m (101 ft⋅lbf) at 5200 rpm. Bore and stroke is 78.0 mm (3.07 in) and 83.6 mm (3.29 in). It was a 16-valve engine with multiport, for 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. Applications:. NX SE (United States and Canada). (Australia and Japan).

It has the same head as the CA18DET, however it did not use piston oil squirters that are found on the CA18DETs. A crank girdle as found on all CA18DET's is fitted to some versions for some markets, Nissan's parts data system 'FAST' has to be consulted or the sump removed to determine if it's fitted.

1985-1990 '1.8Xtt' and 'Euroform Twincam Turbo' 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. 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 tractibility. 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 motor 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.

However the blocks are similar, and it is possible to fit the DOHC CA18DE/T twincam head to the SOHC CA20 block. However the DOHC/SOHC manifolds are different and the timing pulley/belts are not compatible. Despite this, CA20DET turbos have been built. Tomei and JUN of Japan produced 2 litre stroker kits for the CA18. Also companies Norris Designs and Spool Imports produces CA20 stroker kits as well as a CA20 engine.
