Sold a unique experimental Ferrari turbo engine from the eightiesApril 16, 2020
In Switzerland, an experienced Ferrari eighties turbo engine is for sale. The unique engine is assembled in only a few copies – in open sources there is data only about one more surviving engine, which is exhibited at the Ferrari Museum in Maranello.
This is an eight-cylinder engine with a camber angle of 90 degrees and a displacement of two liters. The index – F121A is stamped on the cylinder block, but the engine of this model has never been mass-produced. The serial number of the unit is 00002.
In the eighties, Ferrari produced two-liter turbocharged V8s in series: the 208 GTB Turbo coupe and the 208 GTS Turbo Targu for the Italian market were equipped with F106D engines without an intercooler, and the GTB Turbo and GTS Turbo models that replaced them received an engine in the F106N version with an intercooler.
Although the displacement is very close, the geometry of the cylinders differs dramatically. The experimental engine is very short-stroke (cylinder diameter 77 mm, piston stroke 53.6 mm), while production engines were long-stroke (66.8 x 71 mm).
Heads – with four valves per cylinder. These appeared in 1982 on three-liter naturally aspirated F105AB engines of the same family as the 308 GTB Quattrovalvole, 308 GTS Quattrovalvole and Mondial Quattrovalvole sports cars. But two-liter supercharged engines to the very end had only two valves per cylinder.
Finally, serial engines were equipped with only one KKK German turbine for both halves of the engine – there was nowhere to place two turbines due to the transverse arrangement of the power unit. But the experimental engine is equipped with two turbochargers of the Japanese company IHI – and the transmission shows that it is intended for longitudinal installation.
There were other differences that can be seen on the engine at the Ferrari Museum: the experimental unit was equipped with a Weber IAW electronic injection system with two nozzles per cylinder. Serial engines were equipped with a K-Jetronic mechanical system.
The prototype engine was created in the mid-eighties under the guidance of motorist Nicola Materazzi – probably during experiments to create a 2.9 turbo engine for the 288 GTO or F40 supercar. According to official figures, the power was about 400 horsepower at 7500 rpm.
Five years ago, this engine was already surfacing: then at the RM Sotheby’s auction in Paris, it was sold for 38,025 euros. The new owner had plans to build a track sports car – but the plans have changed, and now he is selling the engine. A piece of history Ferrari can be yours for 40 thousand euros.
