Japanese automakers have ascended the auto industry’s ladder to become some of the most popular and consumer friendly in the whole world.

Once known simply as the automotive company that built modest commuter cars like the Brat ('78 to '87), Subaru (a division of Fuji Heavy Industries) became internationally known for their boxer engines. Beginning in 1989 and continuing through to the present day, Subaru's horizontally opposed EJ-series motors are the mainstay engines of their model lineup.
Subaru has long been known for building some of the most capable and versatile vehicles in the world.
The Japanese company has long been known for producing fantastic, rally-inspired, performance-oriented vehicles to add to their pedestrian line-up. While it may not have production vehicles that can keep up with something like a Corvette Z06, this smaller automaker does still hold the advantage in the all-wheel drive performance car department.
But consumers look onto Subaru as affordable little tunable sports car. The Impreza STI WRX for instance can be tuned to up to or more than 550hp fairly easily.

Here is our top Subaru Engines list


Great engine to install and leave it alone. Too expensive and time consuming to build up.

260 PS/ 3629cc / 335 N·m / stock performance

The (Japanese: Subaru EZ series) was introduced in 1999 in the Japanese market, in the Subaru Outback, and in 2000 in the United States market. It is a flat-six, 24-valve, quad cam motor with an aluminium block and heads. The number of exhaust ports per cylinder varies. It is available in EZ30 and EZ36 variants. Though the second iteration of the EZ30D used from 2003 to 2009 was heavily updated from the early EZ30D used from 2001 to 2003, Subaru continued to identify it as EZ30D. "EZ30R" is a false engine code often used on the Internet for the later EZ30, but Subaru has never used it as an official engine code. The later EZ30D received new cylinder heads with 3 exhaust ports per head and variable intake valve timing. All use dual timing chains and coil-on-plug ignition.

The EZ36D, FB25, FA20 as well as Subaru's diesel EE20 engines incorporate an asymmetrical connecting rod. This design has been extensively used over the years in heavy diesel engine applications. The offset connecting rod was designed to allow additional displacement from a reduced dimensional foot-print. The design also reduces stress on the rod bearings and engine crank.
