The Turbodelta is one of the more obscure Alfa Romeo homologation specials. Autodelta built only around 400 of them to qualify the Alfetta GTV for Group 4 rallying. Each was a standard 2.0 GTV from the Arese line, converted with a KKK turbocharger, pressurised Dellorto carburettors, and cooling vents cut into the inner wings and bonnet. The vented panels were painted matt black whatever the body colour, and inside there is a turbo boost gauge. This red 1979 car is said to be one of just two genuine examples in the UK.
It was imported from Germany in 2021. The page gives 51,647 km on the odometer (about 32,000 miles). The last work in Germany was in May 2020 at 50,500 km, by Formula GT, and covered front brake calipers and pads, spark plugs, fluids and filters, and four new tyres.
Since arriving in the UK, the car has had roughly £20,000 of work. The engine came out to cure oil leaks and the cylinder head was reworked. The carburettors were rebuilt, the fuel system was renewed, and a programmable boost distributor was fitted. The paint is described as presentable but not concours, with an excellent underside. It is MOT-exempt, but will be supplied with a new 12-month MOT, and the invoices and import paperwork come in a file.
