When it comes to custom-built cars, many come up short in the pursuit of maintaining the essence of the car it was built upon. Fortunately, that is not the case with this highly customized Ferrari 512 BB.

In 2002 well-known Ferrari specialist and tuner Bob Norwood, previously of Norwood Auto Italia, was commissioned to build the custom Berlinetta Boxer. Initially, the stock 4.9-liter engine was swapped out for a highly tuned 5.0-liter Testarossa unit. Having improved the internals and a host of other mechanical features, the car reportedly made upwards of 1,100 horsepower. The car’s popularity among the Ferrari community grew—so much so that it was featured in the May 2002 issue of Forza.

However, the car would later undergo further improvements. While the 1,000-plus-horsepower engine was impressive in its own right, it affected the day-to-day drivability of the car. As such, another engine swap would take place. The work was entrusted to marque expert Paul Newman of Barrie, Ontario. In 2018 Newman would oversee a host of changes, most notable among them the transplant of a factory F512 M engine. According to the consignor, the engine was purchased directly from Ferrari by Newman—no small feat, considering only 501 F512 Ms were ever produced worldwide. Now utilizing a 440-horsepower flat-12 engine, one of the last of its kind, the custom 512 BB could now be enjoyed for normal and reliable road use.

In order to further ensure the car’s drivability, the Ferrari features a host of improvements and upgrades. Custom carbon-fiber air boxes were installed, along with Ohlins coilovers that featured special valving and custom spring rates. The car would also make use of a one-off, full stainless-steel exhaust system with titanium mufflers fabricated by Mark Robles. Further, in order to support the chassis’ increase in power, a custom braking system was also built. The BB also benefits from air-conditioning for comfortable warm-weather touring.

Riding on custom-built 288 GTO–like multi-piece forged wheels, the Boxer is a natural blend of new and old Ferrari elements. Its 512 BB chassis and body, F512 M drivetrain, and menacing Nero exterior add up to a truly unique experience, suitable for any hot rod connoisseur or Ferrari enthusiast.
