The legendary Nissan Skyline GT-R, the predecessor of the current Nissan GT-R, is one of the most revered Japanese sports cars of all time, and its career spans over half a century. The Skyline GT-R is famous for a number of reasons, and one of the biggest is due to the engine that lurks beneath the hood. Since the introduction of the R31 generation, Nissan has stuffed RB inline-six engines into these compact sports machines, and as we've witnessed many times before, these engines can be tuned to produce massive performance. The owner of this crazy RB-powered speedboat clearly had the tuning potential of this engine in mind when he decided to take the famous JDM engine to the water, and the results are more than 900 horsepower of sheer awesomeness.

On the small islands of New Zealand, the humble boat plays a significant role in the lives of ordinary people. Combine that with an addiction to JDM cars, and it would only seem natural that this thing exists. Powered by an RB30 inline-six engine, this speedboat, originally built by Tony Ward of Kwikkraft fame, is now a super speed boat. The RB engine was most famous for the twin-turbo 276-horsepower RB26 that debuted in the R32 Skyline GT-R, but over the course of its life, it was available in a number of displacements with and without turbos. This RB30 was a 3.0-liter featured in the retro R31 Skyline GTS, but never featured a turbo in any OEM Nissan product. Tuning house Tommykaira turbo'd it, however, and a turbocharged version was even used in the Holden Commodore.

In this iteration, the motor was rebuilt with a stroker kit and 94mm crank to increase its capacity to 3.4 liters, after which a single Borg Warner 9180 EFR turbo was strapped to its side. According to the owner, this motor produces a massive 914 hp and 791 lb-ft of torque. In a boat that's just 15.5 feet long, that should mean explosive performance.

In the video, we get a glimpse of the build process, and the end product looks like something you'd expect to see from a manufacturer with a proper assembly line. We must admit that it feels a bit unnatural to hear that trademark RB sound, accompanied by blow-off noises while watching a video of a boat cruising the open waters, but that makes this water toy even cooler. We'd love to see this thing go up against Lamborghini's 4,000 hp luxury yacht, but our money is on the lightweight Kiwi. Either way, we think Paul Walker would be more proud of this creation than the latest Fast & Furious film.
