WTK-CA18

[Duo-x2]

Would really like to know if the CA-18 uses a timing chain or belt..If it uses the belt is it hard to get it @ a local parts shop?..also the durablility of the engine components.eg. water pump, starter.......Thanks..

I had a carbureted CA18 and mine was belt drive and I used to buy them by PT auto parts , I think they moved from Petit Bourg to over the hiway El Socorro. I also bought a water pump by El socorro Auto Supplies. P.S. It was a very powerful engine.Make sure and check the timing belt when U buy the engine and change one time.

CA18de and det both use timing belts ( I believe its 152 teeth). These engines are old so it is a good idea to change the water pump and timing belt before you install. Parts are pretty easy to find, you can get oem at nissan or I order from Tuner Imports. Generic replacement parts can be found at roach's, A1, Mathuras and many other places. The CA is very durable and lots of other nissan parts can be substituted. Lots of fun and power once tuned properly.

33 hertz > Well said. In addition to hertz's contribution, there are many versions of the CA-18 series. Although some of the parts maybe interchangeable, the series and year needs to be known otherwise is real headache. The series available are:

The CA18(i) is a naturally aspiration engine it delivers 91 hp (68 kW) at 5200 rpm. The fuel in this engine is not delivered via Multi Port Fuel Injection (E letter code on MPFI engines), it's instead delivered by Throttle Body Fuel Injection hence the (i) letter on the engine code. 83.0 x 83.6 mm bore and stroke, 1,809 cc (110.4 cu in).

The CA18DE is a 1.8 L DOHC 16v (1809 cc) engine produced from 1987 through 1989. It produces 131 hp (98 kW) @6400 rpm and 159 N·m (117 ft·lbf) @5200 rpm. 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.

The 1.8 L (1809 cc) CA18ET produces 135 hp (99 kW) and 141 lb·ft (183 Nm) from a single Garrett T2 turbocharger which did not feature an intercooler (Autocar 1986). It was built from 1984 through 1990. The engine has fuel delivered via Multiport Fuel Injection.

The 1.8 L CA18DET was the last version of the CA engine to be released. It produces 169 hp (124 kW) and 166 lb·ft (228 Nm). It received 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 is 83 mm (3.3 in), and stroke is 83.6 mm (3.29 in). This near square design, coupled with the head design, allows CA18DETs to spin well beyond 8,000 rpms, even in stock trim. The CA18DET is a robust built engine considering that many people have produced over 600 hp (450 kW) with modification. Often referred to as the four cylindered RB engine

The 1.8 L CA18(s) was a carbureted version of the CA engine available in Japan. It produces 90 hp (66 kW) and 110 lb·ft (149 Nm). Bore is 3.27 in (83 mm) and stroke is 3.29 in (83.6 mm).

There are also two versions of the ca18det, the older/jdm version and the newer local/edm version. Both are almost identical except for the heads. The edm version has a 4 port intake manifold where as the jdm version has a 8 port intake manifold with a actuator controlled butterfly valve system. The fuel rail and position of the injectors are also different.

The jdm version is supposed to improve torque in stock form while the edm flows better and is recommended for modified engines.
