The three-liter EZ30 engine was the flagship engine of all large Subaru cars for a full decade (1999-2009). It replaced the EG33 and in turn was gradually superseded by the more modern EZ33. The power unit was designed from scratch, and did not become a revision of some old motor, which allowed the designers to initially introduce advanced systems and technologies.

Subaru engines
Subaru is a Japanese automobile manufacturer owned by Fuji Heavy Industries (FHI). Subaru cars are multiple winners of various auto races, and the brand itself is often the standard and benchmark for other automakers.
Subaru uses a four or five letter code to label its engines.
- The first letter is always Latin E (from engine) (before the FB series).
- The second letter indicates the engine family.
- The next two indicate the displacement (or version, before 1989).
- The fifth character is optional and indicates the version, for example: turbo, DOHC, Fuel Injection, etc.
Unlike most manufacturers who use in-line and V-shaped configurations, Subaru prefers boxer engines, the sound of which is difficult to confuse with something else. The most famous is the EJ series. Subaru’s EJ20 and EJ25 boxer engines are probably one of the most famous and popular among all encountered. In atmospheric versions, they can be found in different models, and in turbocharged versions, most often under the hood of the legendary Impreza WRX and WRX STI. Other models of Subaru engines under the designation FB20 and FB25 are also common. Of the 6-cylinder engines, on larger cars, there are EZ30 and EZ36.
The catalog contains engines for the following Subaru models: Baja | Forester | Impreza | Impreza WRX | Legacy/Outback | Tribeca | XV.

Engine Subaru EJ25
The EJ25 engine, which had a displacement of 2.5 liters, was launched by Subaru in 1995. The block of this engine was identical to the block of the EJ20 engine – just like its older brother, it was made of aluminum alloy and had a height of 201 mm. The only difference was in the diameter of the cylinders – unlike the 2.0-liter engine, which had 92 mm, the 2.5-liter engine had 99.5 mm. Continue reading Engine Subaru EJ25
Engine Subaru EZ36
The production of EZ 36 boxer motors began in 2007 at the Japanese Gunma Oizumi Plant and continues to this day. EZ 36 is a unit designed for gasoline with an octane rating “95”. The engine block is made of aluminum, fuel injection – injection; depending on the modification, the power can be 245 hp. and 258 hp. Continue reading Engine Subaru EZ36
Engine Subaru FA20
The FA20 is a completely new two-liter engine with an aluminum cylinder block. It is compact and takes up minimum space in the engine compartment. With its power ratings, this engine consumes a minimum of fuel, having fuel economy indicators in mixed mode at 7.8 liters per 100 kilometers. For a mid-size crossover, such fuel consumption figures are almost record-breaking. Continue reading Engine Subaru FA20
Engine Subaru FB20
The FB20 engine has an AVCS variable valve timing system on the intake and outlet camshafts. The timing chain uses a maintenance-free chain. The engine is characterized by the installation of a plastic intake manifold with TGV flaps at the intake to improve environmental performance. Most often, this engine is called FB20B, its power reaches 150 hp at 6200 rpm, with a torque of 197 Nm at 4200 rpm. Continue reading Engine Subaru FB20
Engine Subaru FB25
The FB25 boxer engine is an aluminum 6-cylinder injector with a nominal displacement of 2498 “cc” and a pair of light cylinder heads, each equipped with two camshafts. Gas distribution scheme – 16-valve DOHC, compression in the range of 10.0-10.3 (after 2014). The camshafts use a dual AVCS system, each driven by a maintenance-free timing chain. Continue reading Engine Subaru FB25
Engine Subaru EJ20
Mass production of the EJ series engines began back in 1989. The first car to receive the 2.0L EJ20 powerplant was the Subaru Legacy. This engine replaced the outdated EA82 engine with a volume of 1.8 liters. Continue reading Engine Subaru EJ20
