Production estimates for the Flachtbau (Flat Nose) vehicles (also referred to as Slant Nose and Slope Nose) range from 236 to 264 during the period from 1981 to 1986 when the modifications were only available through Porsche’s Sonderwunsche Programme (Special Wishes Program) in Germany. Completed cars were taken from the factory and delivered to Werke 1 where the modifications were done on a custom order basis. In addition to the body work and custom interior appointments, most customers specified the “Increased Performance” engine option which borrowed numerous modifications from the Group B (Gruppe B) racing engine. The optional engine (as installed in this car) was conservatively rated at 330bhp and included an upgraded turbocharger, larger inter-cooler, high-lift cam profile, boost  increase from .8 to 1.0 bar, and a free flow 4-pipe exhaust (the two tips exiting the left rear corner being for the waste-gate).

Starting with model year 1987 (and because the option was then offered as standard production option M505 to U.S. and M506 to R.O.W. customers) the Slant Nose cars were built on the assembly line along with the regular 930 Turbos. The M505 options cars for the U.S. were built with the standard (and already DOT approved) front Turbo valance instead of the R.O.W. air dam w/racing oil cooler which was deemed to be a possible fire hazard in event of a crash. Porsche elected to avoid this potential liability in the American market by moving the oil cooler to the passenger-side rear vent opening on the M505 cars. The engine and other specifications remained identical to the non-M505 Turbos offered in the U.S.
