The most common units of the GA series are, of course, 1.5-liter GA15DS and GA15DE. At first it was a carbureted GA15DSB, and in 1994 it was replaced by the GA15DE with multi-point electronic fuel injection. Thanks to electronic injection, the power increased to 105 hp at 6000 rpm, and the torque reached 135 N*m at 4000 rpm. This engine was produced until 2000.
Like all other 4-cylinder engines of the GA series, these engines have a simple design: a cast-iron block, an aluminum head, and two timing chains, since the crankshaft is connected to the camshafts through an intermediate shaft. There are no hydraulic lifters.
Different indexes for engines due to the fuel system:
- GA15S is a carbureted version with a single 12-valve camshaft. Its power is quite decent for its class 85 hp and 123 Nm.
- GA15E – everything is the same here, but it costs distributed injection, so this modification managed to get a little more, namely 97 hp and 128 Nm.
- GA15DS – the combination of a carburetor and a sixteen-valve head with two camshafts gives an impressive 94 hp and 126 Nm.
- GA15DE – the most common version uses multi-point injection, a DOHC 16v head and a proprietary ECCS electronic control system. Power corresponding to 105 hp and 135 Nm.
The engine was installed on:
- Nissan Sunny 2 (B12) in 1985 – 1990;
- Nissan Pulsar N13 in 1986 – 1990;
- Nissan Pulsar N14 in 1990 – 1995;
- Nissan Pulsar N15 in 1995 – 2000;
- Nissan AD 2 (Y10) in 1990 – 1998;
- Nissan Presea 1 (R10) in 1990 – 1995;
- Nissan Presea 2 (R11) in 1995 – 2000;
- Nissan Rasheen in 1994 – 2000.

Disadvantages of the GA15DE engine
- The carburetor versions have the most problems. Due to clogged strainers and jets inside the fuel system, the engine starts to work very unstable, or even just stall for no reason. The fault is usually low-quality gasoline.
- On injection engines, the idle valve is most often clogged, which is expressed in unstable engine speeds. Although it is not very difficult to remove the assembly itself for cleaning, it is best to contact a specialist, as there is a chance of accidentally damaging it.
- Also, the speed of this power unit can float due to a failure of the mass air flow sensor. Usually, experienced servicemen offer to change it, since cleaning it does not help him for a long time.
- If a strong oil burner has begun, more than a liter per 1000 km, then it is high time to assess the condition of the oil scraper rings and caps. Replacing them helps in about 50% of cases. If not, then get ready for a very expensive overhaul.
- Sometimes the lubricant flies out into the pipe due to the drying of the gasket, which should limit the ingress of fuel and lubricants along with gases from the crankcase into the intake. It is necessary to inspect the crankcase ventilation filter, if it is covered in oil, then this is definitely the reason.
