Ferrari's '80s creation was emulated 16 years later by a tuner, marking a significant achievement for the latter.

In the world of modified supercars, one name stands out - the Koenig 512. This unique vehicle, a product of the popular tuning house Koening Specials in the 1970s and 1980s, is currently up for sale.

The Koenig 512 started life as a Ferrari 512 Berlinetta Boxer, but it's the modifications that set it apart. The car received its widebody treatment just a year after it rolled off the assembly line, followed by a series of upgrades that included a suspension upgrade, Campagnolo wheels, and engine work.

The most significant modification, however, was the twin-turbo conversion, which boosted the engine's output to a staggering 644 hp, making it more powerful than the Lamborghini Countach Quattrovalvole (449 hp) and Ferrari Testarossa (385 hp) in 1986. In 1986, the car's engine was further rebuilt with stronger internals, fuel injection, and twin Rajay turbochargers.

Willy Koenig, the head of Koening Specials, was the mastermind behind this powerful creation. Unfortunately, the history of who first sold the car to Koenig in 1978 or where the twin-turbo conversion was performed remains a mystery.

The Koenig 512, with its 644 hp, is a testament to the appreciation trend for older modified supercars. Prices for such vehicles are expected to follow this appreciation trend, and the Koenig 512 is no exception. Currently, the one-off Koenig 512 is available for purchase at Rock n Roll Classics in Belgium for €249,900 (approximately £215k / $292k).

Interestingly, the Koenig 512 is less expensive than a stock example of similar cars, which can cost 15-30 percent more and be less powerful. The car boasts only 10,000 miles (16,000 km) on its odometer, adding to its appeal.

For those who miss the era of questionable hairstyles and turbo lag, the Koenig 512 might just be the perfect time machine. Its unique history, powerful engine, and affordable price make it a standout in the world of modified supercars.

So, if you're in the market for a piece of 1980s supercar history, the Koenig 512 could be the car for you. You can find the listing for the Koenig 512 here. However, information about the current location or price of the car for sale is not provided.
