A 1979 Ferrari 512 BB, extensively modified by Ferrari specialist and tuner Bob Norwood, is being auctioned off by RM Sotheby’s on Friday, January 17.

While this 512 BB has spent most of its life much like any other, Norwood got his hands on it back in 2002 and set about turning it into an absolute animal. He did just that by swapping out the standard 4.9-liter flat-12 engine for a highly-tuned 5.0-liter Testarossa powertrain that was cranked up to a remarkable 1,100 hp. The car quickly became revered in Ferrari tuning circles and was featured in the May 2002 issue of Forza.

According to the listing, the car retained this crazed Testarossa engine until 2018 when in a bid to improve its day-to-day driveability, it was fitted with a factory flat-12 engine from a Ferrari F512 M with 440 hp. Numerous other modifications were made at the same time. For example, the customized 512 BB includes bespoke carbon fiber air boxes and Ohlins coilovers with special valving and custom spring rates.

In addition, the car features a bespoke stainless steel exhaust system with titanium mufflers and a new braking setup. As it stands, the car sits on a set of bespoke wheels inspired by those of the 288 GTO and viewed from the outside, doesn’t appear all that different to most other 512’s.

Curiously, the listing fails to state the mileage of the chassis nor the mileage of the F512 M engine. Nonetheless, the car is still expected to sell for between $225,000 and $275,000.
