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.

Applications:

GA16E

edit

The GA16E is a 1.6 L (1,597 cc) multi-point fuel injected SOHC engine. It produces 110 hp (82 kW; 112 PS).

GA16DE

TheGA16DEis a 1.6 L (1,597 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 (82 kW; 112 PS) at 6000 rpm and 146 N⋅m (108 lb⋅ft) at 4000 rpm, the North-American second-generation (1995-1999) NVCS (VTC), which produces 115 hp (86 kW; 117 PS) at 6000 rpm and 146 N⋅m (108 lb⋅ft) at 4000 rpm, and a European non-NVCS (VTC) version which makes 102 hp (76 kW; 103 PS).

The two variants of the North American NVCS engine are distinguished as such: in addition to differences in theintake manifoldsand (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 siamesedexhaust manifolds,while others keep the exhausts separated until thecatalytic converter.

The GA16DE shares its block andcrankshaftwith the GA16i; however, theirtiming chaincovers,connecting rodsand 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.

EarlierECUscontained 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.

Applications:

GA16DNE

edit
GA16DNE, front (Super Touring Sentra)

TheGA16DNEis a Mexican-specification 1.6 L (1,597 cc) engine, which produces 105 hp (78 kW; 106 PS). The main differences between the DE and DNE are noNVCS(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 3oxygen 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.
