Whenever the Subaru BRZ and its Toyota twin are talked about, the conversation inevitably turns to whether they would be even better sports coupes with more power. Since their introduction, rumors have popped up suggesting possibilities like more displacement turbocharging or even a hybrid setup to increase horsepower, but nothing has come to pass. Japanese tuner Jun Auto has decided on a completely different way to boost performance by chucking the 2.0-liter boxer four-cylinder entirely in place of a beautiful 2.4-liter V8.According to the YouTube description for this clip, the engine is based on two of the 1.2-liter inline four-cylinder units from a Kawasaki Ninja ZX-12R motorcycle . The result is a mill that makes a claimed 362 horsepower and revs to over 11,000 rpm. It also sounds like automotive nirvana. Finished in an eye-catching contrast of bright yellow paint with white wheels and a black wing at the back, the V8 BRZ certainly doesn't hide its performance, either. This video's text is in Japanese, but knowledge of the language isn't necessary to understand what's going on.
