Nissan CA20S engine
Content
Nissan CA is a piston internal combustion engine with a volume of 1,6 to 2 liters. It was developed for small Nissan cars and replaced the Z engines and some smaller L-series 4-cylinder engines.
The motor is completely metal, its head is made of aluminum. Unlike the internal combustion engines of the Z and L series, instead of an iron timing chain, it has a gas distribution belt. This makes this model cheaper.
Early CA models had 8 valves driven by a single camshaft.
Later versions of the engine received an electronic gasoline injection system.
The CA series units have been designed to be compact and lightweight, fuel efficient and fuel efficient compared to their Z series predecessors.
This is the first engine in which a system was installed to reduce exhaust gases into the environment, hence the name of the CA engine - Clean Air - clean air.
In later versions, the number of valves was increased to 16, which made the motor more powerful.
Due to the rather high cost of the metal, the production of engines was discontinued in 1991. They were never produced in a turbocharged version.
The 1,8 and 2 liter models were replaced by four-cylinder Nissan SR series engines. Subcompact 1,6 engines were replaced by the GA series.
Model description CA20S
In our article we will talk about the Nissan CA20S engine. The serial number speaks of the “clean air” system (CA, clean air), 2-liter engine capacity (20) and the presence of a carburetor (S).
It was produced between 1982 and 1987.
Working at the limit of its capabilities, it produces 102 horsepower (at 5200 rpm), its torque is 160 (at 3600 rpm).
His later models were the CA20DE with twin camshafts and electronic fuel injection, the CA20DET with turbocharging, the CA20T with turbocharging only, the CA20T with turbocharging and electronic petrol injection.
Models of Nissan cars on which this engine was installed: Stanza, Prairie, Auster, Bluebird (Series S, U11, T12), Laurel, Skyline, Cedric / Gloria Y30, Van C22 (Vanette).

Maintenance and repair
As we have said, the engine is economical in terms of gasoline consumption. Oil consumption is also minimal. According to the feedback from car owners with this engine, we can conclude that it is reliable, durable, hardy, does not require repair for a very long time (up to 200, and sometimes up to 300 thousand kilometers traveled).
The price of a fully equipped engine ranges from 50-60 thousand rubles.
As for the purchase of spare parts for this model, although the cost for them is not high, it will be quite difficult to find them on the secondary market, since the model has not been produced for a long time.
For example, the price of a fuel pump is 1300 rubles, a set of four candles is 1700 rubles, replacing an engine mount will cost you up to 1900 rubles, and a timing belt - up to 4000 rubles.
The second problem may be the lack of relevant literature on the repair of this model and the unwillingness of auto repair shops to take on such work.
However, cars of that generation provide easy access to the engine, so many drivers repair the engine themselves.
In winter, this motor will need up to 20 minutes of warm-up;
The camshaft position sensor may be damaged, this should be paid attention to.
Hack and predictor Aviator
To date, there are many cars left on the go (for example, Skyline, Stanza, Laurel) with CA20S series engines still running, which indicates their durability and reliability. This is facilitated by an all-metal body. Basically, tuning enthusiasts buy such cars, but according to their reviews, they are in no hurry to part with their native engines, but modify only the appearance of the car.
If we take into account all the features of this engine, namely its efficiency, environmental friendliness, ease of repair, then we can say that it was one of the best engines of its time.
