The SUBARU EA ENGINE is a series of automobile internal combustion engines manufactured by Subaru
Subaru
, a division of Fuji Heavy Industries . All EA series engines are of a flat-4 design, and have always been water cooled.

The EA series engines have aluminum heads with aluminum blocks. Each cylinder has two valves, one for exhaust and one for intake. They came in either an OHV pushrod or SOHC configuration.

EA-82

The Subaru
Subaru
EA-82 engine was originally intended to be a 2.0L engine as its prototypes were, but Subaru
Subaru
destroked it to 1.8L for production, despite of having same displacement on the older EA81 engine; however the EA82 bore kept being the same found on their newer EJ20 engine. The EA82 was produced from 1984 to 1994. It came either with carburetor , single point fuel injection , or multi port fuel injection and hydraulic lifters. Most of the technical advancements introduced to the EA82 were utilized in the next generation Subaru
Subaru
EJ engine , specifically, the SOHC valvetrain, and multi-point fuel injection.

CHRONOLOGY

SUCCESSOR Subaru
Subaru
EG engine

The ER series is a flat-6 engine with a displacement of 2.7L manufactured by Subaru
Subaru
, a division of Fuji Heavy Industries . The ER series has aluminium engine blocks and aluminium cylinder heads. It is found on the 1988-1991 Subaru
Subaru
Alcyone VX (XT-6 in the United States).

Created as a refined luxury engine with improved power over the EA82T, Subaru
Subaru
introduced the ER series engine in 1988 exclusively to be featured in the Subaru
Subaru
Alcyone VX. Like the EA series engines, the ER series engine featured 2-valve cylinder heads with hydraulic lash adjusters and the block shared the same bore and stroke. While recognised as bearing many similarities to the Subaru
Subaru
EA82 engine, there are numerous differences in design between the two engines and a large portion of parts are unique to the ER27. The oil and water pumps are unique to the ER27, sharing similar bolt patterns and design to the EA82, but being of a higher flow in both cases. The intake manifold uses a two piece design with a lower section bolting to the heads containing the coolant bridge, injectors and various vacuum lines. The upper intake manifold then bolts to the lower section and is unlike the EA82 or EJ22 "spider" manifold designs in that there is no central plenum chamber. The valve timing system is belt-drive using two individual timing belts, curiously one belt uses a spring tensioner (like the EA82) whilst the other uses a hydraulic tensioner (like the EJ22 ). Both JDM and USDM versions of the ER27 used multi-point electronic fuel injection. The ER27 designation was the first time Subaru
Subaru
incorporated the engine's displacement into the series name and all future engines have retained this nomenclature.
