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

Here is our top Subaru Engines list

Subaru’s 2.0L turbocharged “FA” H-4

Heading in the right direction !

268 PS/ 2.0L / stock performance

Few people would argue the downsizing trend has yielded a bunch of uninspired, underpowered 4-cyl. engines. They’re generally pretty good.

But one editor, struggling to mentally sort the 15 turbo-4s we drove for Ward’s 10 Best Engines over the past two months, rightly notes it can be hard to tell them apart.

Not true for the 2.0L turbocharged “FA” boxer 4-cyl. in the Subaru WRX, which introduces an uncommon sense of immediacy to the turbo-4 experience. The WRX’s rally-car pedigree shines through like a klieg light as the engine provides seemingly instant neck-snapping gratification at step-off. Turbo lag? Not here.

We tested this 2.0L turbo last year when it was new in the Forester CUV, but it comes back to us with an extra 18 hp in a sporty new application, which means an impressive specific output of 134 hp/L.

The WRX version features lots of fresh content intended to extend the performance envelope, including new camshafts, valves, rocker arms, cam sprockets and electronic controller. Plus, valve springs have been re-engineered to accommodate higher revving.

The refreshed engine now redlines at 6,700 rpm (with 6-speed manual transmission), instead of 6,000 rpm in the Forester. And torque peak lasts longer in the WRX – from 2,000 to 5,200 rpm, instead of 4,800 rpm in the Forester. The changes allow the WRX to develop its peak power using 15.9 psi (1 bar) turbo boost, rather than 17.1 psi (1.1 bar) in the Forester.
