Subaru loves boxers. No, not the kind that beat each other into bloody pulps, we're talking about the engine design, which places the cylinders directly across a horizontal plane, almost like they are swinging alternating punches away from the crankshaft – hence, the boxer name.

There are lots of good reasons to love the boxer engine – it allows for a decidedly low center of gravity and is inherently smooth due to its built-in balance – and Subie has certainly done much to advance the configuration since the days of the original Volkswagen Beetle (also boxer-powered). But what if you want your cylinders arranged in a V?

Well then, there's always the ever-popular engine swap. While some would be content to drop in the tried-and-true Chevy V8, not everyone wants Bowtie power in their engine bays. At least one Subaru Impreza owner decided on nothing less than a BMW V10 ripped from under the hood of an M5.

Thankfully, we have video evidence that such a beating-heart transplant can pay big dividends. See for yourself in the video after the break, which was apparently shot just after the conversion was completed and before the engine had been fully tuned. Enjoy!

      Obscenity. And it's only RWD. Too much power, not enough stickum.

      doesn't sound like a subie but neither does it sound like an M5. I am only seeing a single exhaust coming out the back. It seems like a dual exhaust would be a minimum requirement. no doubt it screams around the track and smokes a set of tires, but I'd like to check under the hood.

        It's definitely the V10. It is possible to recombine the exhausts at the back. Not sure why you'd do this but.. they did it!

        Better than ricer pimping their Dodge Neon with wings and fart can exhaust to make their car sound quicker than it actually is

      Whoever did this is an idiot who ruined a great car - albeit with a great engine. True, to some all cars are equal and the only difference is the engine hence the bigger the better.... Morons.

          Would an overweight body with expensive touchy-feely bits and a higher quality paint job actually make the engine any better? No d-bag stigma seems like an upgrade for the driver...

      Weak. Should have just stayed with the boxer. Everyone's talking about sound - V8 Mustang, Corvette sound way better. FAIL

          Along with Laser and Oceanblue, you have a giant hate for either a single car or a manufacturer. In this case, it's a car. All because the Corvette ZR-1 beat the GT-R around the Nurburgring. *Waits for him to come up with the excuse that it had "race slicks" on it to achieve that time, when it actually didn't.*

      Sounds great and all but a bit pointless IMO. Especially when you consider the capability of most Japanese-spec 2.0s out there than can achieve such power without ruining the car's already near-perfect handling and weight distribution. And to top it off, they turned it into a RWD car? Major FAIL! This is coming from a Mitsubishi fan btw.

      No way that's a V10. FAIL

        Someone things they know what they're talking about because it doesn't sound like a viper.. Pushrod V10 is a little different than a 4-valve V10...

        It doesn't sound like a V6. Sounds like a 4. If in fact that is a BMW V10 it sounds weak. Mustang or Corvette V8 sounds better.

      Its like taking the heart out of a lion and placing it in a sheep, you get mixed feelings.

        Light, agile, runs on all fours. Definitely fair to refer to a Subie as a lion... The soundtrack of a boxer rumble is all the video needs...

      I agree. That sounds wayy too whiny to be a V10 engine.
