With turbocharging prevalent in Formula 1 at the time, Ferrari decided to adopt it on the Italian market 208 GTB in 1982, to redress the power difference between the 2 litre and 3 litre engines, without increasing the tax burden on the client.
The 208 GTB Turbo models had a tubular chassis with factory type reference F 106 DB 100. Disc brakes, with independent suspension via wishbones, coil springs, and hydraulic shock absorbers, were provided all round, with front and rear anti roll bars. All models were numbered in the Ferrari odd number road car chassis sequence, with only left hand drive available. Production ran from 1982 through to 1985, during which time 437 examples were produced in the chassis number range 41357 to 59277.
The transversely mid-mounted aluminium V8 engine was essentially of the same design as that used in the 208 GTB model. It was of a 90 degree configuration, with belt driven twin overhead camshafts per bank, having a total capacity of 1991cc, with a bore and stroke of 66.8mm x 71mm, and a compression ratio of 7:1, bearing factory type reference F 106 D 000.
The engine was coupled in unit with the all synchromesh five speed transmission assembly, which was below, and to the rear of the engine’s sump. It was fitted with an exhaust driven KKK turbocharger unit with waste gate, Bosch K Jetronic fuel injection and Marelli MED 804A electronic ignition, and had a claimed power output of 220bhp at 7000rpm.
