While I’m typically not on board with the whole “LS swap the world” mentality, there are instances where it truly transcends expectations—this build is one of them. Instead of following the usual route of airbag suspension and a standard tune-up, the team at Moore Performance took an unconventional approach with this Subaru Forester, now known as “Project Arkham.” Equipped with a supercharged LSx engine at the front, this unique creation delivers immense power to the rear wheels, distinguishing itself from the typical builds seen today.

Dressed in a Joker-themed paint job, this vehicle emits a growl that far surpasses the infamous laugh of the Batman character. A 1.9L LSA supercharger nestled in the engine’s V configuration boosts output to an impressive 554 horsepower and 534 lb-ft of torque, significantly outperforming any similarly modified flat-four engine. This power is transmitted through a modified GM 4L80-E four-speed automatic transmission, ultimately reaching the back wheels assisted by an upgraded Subaru rear end.

Images of the engine bay reveal the astonishing nature of this Subaru, and regardless of your opinion on the conversion, the craftsmanship involved deserves recognition. The LS’s fundamental simplicity and substantial power potential have transformed this Japanese wagon into an exhilarating vehicle that’s tough to rival.

Take a moment to watch this unusual scene as the Subaru effortlessly burns out in a parking lot, decimating its two rear tires.

Once you’ve processed that clip, enjoy the powerful roar of the 5.3L V8.
