If you thought the 2.0-liter boxer engine pumping out 200-horsepower wasn’t enough, Weapons Grade Performance has a solution.

With a company name as intimidating as the upgrade it’s carrying out on the Subaru BR-Z, Weapons Grade Performance is on the verge of making one of the most powerful BR-Zs to run the streets.

How does it does it pull off this task? Slap a good ol’ American V-8 in there, of course. Yup, W.G.P chose the old-school-but-still-awesome method of increasing horsepower by mounting an LS2 V-8 from a Pontiac GTO that produces 400-horsepower, twice more powerful than the stock 4-pot boxer engine.

While the idea of a V-8 powered BR-Z sounds good, it may not do wonders when it comes to weight distribution. A picture of your pot-bellied uncle is a good comparison to this build. Then again, this sort of uncle can be rather exciting to hangout.

Here’s to hoping that W.G.P will pull off this build, hassle free. We’ll update this review as more information rolls out, as this is a work in progress. And for those that think this is a Photoshop trick rather than the real deal, see the video after the jump for a live shot of the car. There’s no Photoshopping a video…
