This S14.5 makes 717 horsepower on its NA LS3 engine

While browsing YouTube in search of some amazing and rare cars, we came across YouTube user 19Bozzy92, and his video of an LS3 powered Nissan Silvia S14.5 he had the privilege of filming. The vehicle was built by a company called Brill Steel Motorsports, located in Villorba, Italy.

This is what 427 cubic inches of LS3 looks like, in case you were wondering.

Owner Enrico Sartori and his crew were determined to build a fast, completely custom, and race inspired car out of the S-chassis. What originally started out as an LS3 crate motor from the UK, was quickly gutted and replaced with almost everything you can imagine, then stroked to what is now a 427 cubic inch (7.0 liter) NA motor, putting down 717 horsepower and 896 lb-ft of torque to the wheels.

Horsepower and torque levels increase dramatically when hooked up to nitrous, making the car capable of 945 horsepower. The body work of this amazing vehicle is actually a combination of OEM Nissan S14 and S15 parts. The roof, rear quarter panels, and A/B pillars were all used to be recreated in dry carbon. The fender flares, created in dry carbon fiber as well, were inspired by Nakai-San’s RWB 911.

If you’ve got some time to kill, take a look at the rest of 19Bozzy92’s videos on his YouTube channel. He’s captured some great video of some amazing cars and their sounds.
