Officially, Porsche offered a ‘Flat Nose’ or Flachbau version of the 911 Turbo from 1982 following the build of a handful of prototype cars during 1980 and 1981. Early versions of this factory-built special were produced on a 'special request' basis.

The Flachbau model originates from a time when wealthy customers wanted road-going 911 models that imitated the look of the successful Porsche 935 race cars. Kremer Racing and DP Motorsport had already started supplying converted 'Flat Nose' specials, and in 1981 the factory was commissioned to produce a '935 Street' for Mansour Ojjeh, the head of TAG. This car became the first official product of the new 'Special Wishes' program (Sonderwunsch Programm), and was the project that gave momentum to the 930 Flachbau or Flat Nose conversions built by Porsche from 1982 to 1989. Described officially as the 'Turbo SE' for the UK market, the car has also been referred to as a Slant Nose as well as the Flachbau. Double the cost of the standard car, in period it was viewed as the ultimate 930 Turbo and numbers sold were very low. In building any Flachbau, the conversion required extended sills, flared rear arches with vents and narrow and tapered flip-up headlights up front with functional louvres. Aftermarket specialist car builders such as Dage Sport Limited, offered an alternative outlet for obtaining the look of the genuine Porsche-built 'Flat Nose' or 'Flachbau' (Flat Construction) 911.

Currently displaying a non-transferable mark, 'JBW 91Y' is a UK supplied right-hand drive car with the chassis number showing it to have begun life as a 1983 Porsche 911 SC Cabriolet, first registered on 21^st April 1983. By 1989 Dage Sport Limited took on the work to make some dramatic cosmetic and mechanical changes to the car including the fitment of a 930-type 3.3 litre turbocharged '911 Turbo' engine. Dage were known to be specialists in conversions of the 911 to a Flat Nose design; much coveted and appreciated by enthusiasts of the 911 in motorsport. Post conversion, in 1989 Dage Sport Limited utilised 'JBW 91Y' as their company demonstrator. in addition to the Flat Nose conversion, the car benefited from a revamped interior by Zeemax in complementing Red / White leather seats piped with White, and Red carpets . Wearing the iconic Fuchs alloy wheels, but in desirable split rim form, and a Kremer style rear spoiler, the car now displays 72,000 miles of smiles and enjoyment. Based upon a UK supplied 911, the car has the Flachbau looks in a rarely seen right hand drive package.

Over the years the car has been subjected to mechanical work and improvement. In 2011 the car received a top end engine overhaul and a clutch at a cost of £5,565. Front discs and pads were sorted in 2020. Other work has included a new starter motor. Recently, 'JBW 91Y' was treated to a refresh with a repaint and a wheel refurbishment; there is a photographic record of the work done. The car is accompanied by an original Dage Sport Limited sales brochure and a parts catalogue, a new hood bag and two keys. There is also a large collection of invoices and a collection of old MOTs.
