Subaru six cylinder engines come with a history of performance and longevity. It seemed like the only way Subarus could produce more power out of the same engine was to add more cylinders, primarily by adding more cylinders. The result is a strong engine that can last for years of ownership.
When people buy a Subaru they’re choosing quality, durability and reliability. This is why many drivers choose to stick with Subaru’s engines and these qualities are no different in the Subaru six cylinder engines. Let’s take a look at what the Subaru six cylinder engines have to offer drivers over their alternatives.
Subaru has earned a reputation for producing great cars over the years. Not only in the way they perform, but also in their longevity. We’ve seen that Subaru’s engines are no different and that they can last a very long time when properly maintained. The Subaru six cylinder engine is one of the best options you can get when looking for a new engine in your car. Whether you’re looking to replace your current engine or maybe looking to get something more powerful than what you already have, there are plenty of great reasons why the Subaru six cylinder engine should be at the top of your list.
ER 27 Engine
Here’s an engine that was well ahead of its time—the ER27! And, as it turns out, it’s still ahead of the competition—21 years later!
In the 1980s, Subaru worked in collaboration with Toyota to create a new kind of engine for a new kind of car. The Epicyclic Reducer Transmission system was created as a refined luxury engine with improved power and torque over the EA82T engine which it replaced. When the ER27 was introduced, it was the only water-cooled flat-6 automobile engine on the market.
EA series engines from Subaru had their heyday in the late 90s to early 2000s when WRXs, Legacies, Foresters, and Imprezas were kicking a lot of arse on the rallying and road racing circuit. They offered a broad range of power across a part-controlled turbocharger and saw plenty of development in the motorsport scene. As you can probably imagine, it would be quite difficult to realise those same qualities without help from Subaru themselves.
The Australian built EA series engines have long been known for their durability and ability to perform well under high stress applications. However since the closure of the manufacturing plant, these engines have become increasingly hard to find. The Japanese designed ER27 engine is a mechanically similar engine, with many parts interchangeable and comparable in terms of performance.
The Subaru EJ25 is an automobile engine from the company Subaru. It was introduced in 1997 and was used through 2002, when it was replaced by the newer MY03 version of the EZ30. In 1997, the original version of this engine (the EJ25D) first appeared in the Subaru Legacy B4 Sedan, with a twin-scroll turbocharger. The second variety of this engine, known as the short-stroke ER27 came with an active intake manifold called Active Valve Control System (AVCS). It was only 2.7 litres in displacement and had a slightly lower output than most other versions of the EJ series. Both versions were produced in Ota, Gunma, Japan.
The Subaru EA series also known as the Subaru ER27 is a series of flat-6 engines produced by Subaru in the early to mid-1990s. The first EA was introduced in 1988, and was a 2.7-litre engine with throttle-body fuel injection. In 1991, the engine grew to 2.8L, 2242cc and featured DOHC heads. The block, crankcase and intake manifold were unique to Subaru, but many other parts were shared with the Subaru EA81 engine and several other engines found in Japanese vehicles of the 1980s and 1990s.
EG 33 Engine
As if the SVX wasn’t wild enough, the Alcyone featured another unique innovation: a six-cylinder engine. The EG33 was essentially a detuned version of the EJ22 which powered models such as the Legacy and Impreza. The EJ22 had a displacement of 2.2 L and produced 115 horsepower, while the EG33 displaced 3.3 L and produced 170 horsepower! The EG33 was also used in the Japanese-spec Legacy Touring Wagon, but not for long since it was discontinued in 1993 at only 18,000 units produced due to poor sales.
Unlike the SOHC EJ22 it shared some dimensions with,the EG33 featured dual overhead cams; both engines used four valves per cylinder.The EG33 used a single toothed timing belt which drove the exhaust camshafts on each bank in addition to the water pump (mounted on the right bank); the intake camshaft on each cylinder bank was driven in turn by a set of helical gears via the belt-driven exhaust camshaft.
EZ36 and EZ30 Engine
Today’s article is strictly analyzing the differences between the EZ30 and EZ36 engines. I am by no means a car expert, so please take this simply as a discussion of their differences and not an endorsement of one or the other. To begin, let’s talk about how each engine was introduced. The EZ30 was first introduced in Japan, and a twin-turbo version first appeared on the B11S concept car which has only been seen once in history. But this design never made it to production cars as far as I know. The EZ36 was introduced in 2008 for the Tribeca and eventually migrated to certain Legacy and Outback models starting in 2010. And if you’ve read my other content, you already know that Subaru’s naming conventions are weird and confusing at times, so let me clarify these engines further. The “EZ” name comes from the fact that these engines were designed to be used on both horizontally-opposed (or boxer) engines like Subaru normally uses, and also cast-block inline engines which they normally do not use. Thus, they are easy to manufacture across multiple platforms. Continuing with this theme, we see that both engines are flat or horizontal rather than vertical like most Subaru engines
