Engine Nissan GA14DE (GA14S/DS)

4-cylinder engines of the GA14 series have a very simple design: a cast-iron block with an aluminum head without hydraulic compensators. But the timing chain drive is unusual here, it has two chains.

The family includes 3 engines:

• The GA14S is a simple carburetor and only has one 12 valve camshaft. Its power and torque were decent for its time 79 hp and 111 Nm.
• GA14DS – 16-valve head with two camshafts, electronically controlled carburetor and catalyst. Total here is 75 hp and 112 Nm.
• GA14DE – here is a DOHC 16v head and injection injection. This most common modification has a power of 87 hp and a torque of 116 Nm.

The assembly of internal combustion engines was carried out at a plant in the Japanese city of Yokohama from the late 80s until 2000, and then it was transferred to the conveyors of third world countries.

The engine was installed on:

• Nissan Pulsar N13 in 1986 – 1990;
• Nissan Pulsar N14 in 1990 – 1995;
• Nissan Sunny 3 (B13) in 1990 – 1993;
• Nissan Sentra 2 (B12) in 1985 – 1990;
• Nissan Sentra 3 (B13) in 1990 – 1995;
• Nissan Almera 1 (N15) in 1995 – 2000.

Disadvantages of the GA14DE engine

• Owners of carburetor engines must constantly monitor the cleanliness of all kinds of meshes, filters and jets that clog due to bad gasoline.
• On versions with electronic injection, the idle valve fails, as well as the mass air flow sensor. The main symptom is floating idle speed.
• The cause of the oil burner on long runs is most often: stuck oil scraper rings, hardened valve caps or a leaky gasket, which should limit the ingress of fuel and lubricants along with crankcase gases into the intake tract.
