The Ferrari 208 GTS Turbo is one of the six available versions of the 208 model produced by the Italian company. The 208 GTB Turbo is the first road Ferrari to have supercharging via a turbocharger.
The following year it will also be mounted on the GTS Turbo.
At first, the idea of producing a variant with a targa type roof of the 208 Turbo was not even hypothesized, but in response to the demand generated by customers, the 208 GTS Turbo was designed, which was officially launched in 1983.
As for the version with fixed roof, the changes made to the bodywork designed by Pininfarina regarding the 208 GTS are not many: a rather deep front spoiler appears, equipped with five air intakes for cooling housed under the radiator grille.
The front hood is equipped with satin black air vents: the high temperatures generated by supercharging the engine require an increase in the amount of air flow directed towards the radiator.
A pair of electrically adjustable exterior mirrors become part of the standard equipment, and on the lower part of the sides, right in front of the rear fenders, there is a NACA-type air intake, i.e. an air intake seen also in Formula One, easily recognizable by its Delta shape, designed to collect and convey the air flow that caresses, in laminar form, a smooth and flat surface of the frame.
In addition, a rear spoiler is placed at the end of the roof, astride the buttresses that descended towards the car's fenders. The word Turbo is engraved on the rear panel, while the pair of twin exhausts no longer have the protective cover on the two end pipes. Pirelli P7 tires with 16-inch rims are available as an optional alternative to the Michelin TRX, fitted as standard.
Disc brakes, independent suspension with wishbones, coil springs and hydraulic shock absorbers are present on all wheels, in addition to the front and rear anti-roll bar.
All the prototypes are numbered with the odd number sequence typical of road Ferraris. The model is only available with the driver's seat positioned on the left.
Production of the 208 GTS Turbo began in 1983 and ended in 1985. A total of two hundred and fifty units will be built, with chassis numbers from 42863 to 59279. The transversely mounted aluminum V8 engine, derived from that of the Dino 208 GT4, it essentially consists of the same design used in the 208 GTB models. The unit had a 90° V configuration, with double overhead camshafts per cylinder bank, and its camshafts are driven by a toothed belt.
The total displacement is 1,991 cm³, with bore and stroke equal to 66.8 by 71 millimeters, the compression ratio is 7:1 while the internal reference code is F106 D 000.
The drive unit contains in a single block the five-speed synchronized gearbox, located in the lower part behind the engine oil pan. The engine is equipped with a KKK turbocharger driven by exhaust gases, and equipped with a wastegate valve, Bosch K Jetronic fuel injection, and Marelli MED 804A electronic ignition.
The declared power reaches 220 horsepower at 7,000 rpm.
