Nissan GA engine

The GA engine is a 1.3 to 1.6 L inline-four piston engine from Nissan. It has a cast-iron block and an aluminum head. There are SOHC and DOHC versions, 8, 12, and 16 valve versions, carbureted, single-point, and multi-point injected versions, and versions with variable valve timing (GA16DE). The GA was produced from August 1987 through 2013. Since 1998, it was only available from Mexico in the B13.

In the code of the engine, the first two initials indicate engine class, the two numbers indicate engine displacement (in decilitres), the last two initials indicate cylinder-head style and induction type (D=DOHC, S=carburetor, E=injection). In the case of a single-initial suffix, the initial indicates induction type.

GA16DE


The GA16DE is a 1597 cc engine produced from November 1990 through 1999. All GA16DEs have 16 valves and a DOHC head. There are three versions: the North-American first-generation (1991–1994) NVCS (VTC), which produces 110 hp at 6000 rpm and 146 Nm at 4000 rpm, the North-American second-generation (1995-1999) NVCS (VTC), which produces 115 hp at 6000 rpm and 146 Nm at 4000 rpm, and a European non-NVCS (VTC) version which makes 102 hp.

The two variants of the North American NVCS engine are distinguished as such: in addition to differences in the intake manifolds and (resultantly) the heads, earlier motors used pistons with two compression rings and a single oil ring and put out five less horsepower, while later GA16DEs have a single compression ring and a single oil ring. Some engines have siamesed exhaust manifolds, while others keep the exhausts separated until the catalytic converter.

The GA16DE shares its block and crankshaft with the GA16i; however, their timing chain covers, connecting rods and pistons are different. Despite this, it is possible to interchange connecting-rod/piston assemblies between the GA16i and GA16DE with no damage to the valve-train.

Earlier ECUs contained the fuel & ignition maps on a discrete ROM microcontroller, making retuning relatively easy. Later ECUs integrated the maps onto a larger, more integrated microcontroller's firmware, making retuning require the use of a daughterboard.

GA16DNE
The GA16DNE is a Mexican-specification 1597 cc engine, which produces 105 hp. The main differences between the DE and DNE are no NVCS (VTC) and no ECCS plenum. The DNE has a vertical throttle body with an MAF inside; the air filter is diagonally oriented in its air filter housing. Since 2003, the DNE comes with a new ECU and 3 oxygen sensors.

The "N" in its nomenclature stands for "New EGI" (emission system), since this engine does not have an EGR system like the GA16DE. Other Nissan engines with the "N" nomenclature are natural gas powered.
