Only 17 examples of the ultimate 924, the Carrera GTR, were built, and this one is for grabs.

The 924 never was the Porsche’s purist cup of tea, mainly as the model adopted a front engine, rear wheel drive arrangement, an optional automatic transmission (the first Porsche to do so) and Volkswagen’s EA831 2.0 L I4 engine – used in the LT van.

But as far as it was from the German car maker’s pedigree, it didn’t carry the Porsche badge for nothing, shining at various racing events, including the infamous Le Mans.

This hard-looking variant is based on the 924 Carrera GT and GTS, a developed 924 Turbo created to homologate the race car in order to meet Group 4 racing regulations. But while 406 GT and 59 GTS were made in Stuttgart, only 17 GTRs left the factory – of which nine raced at various events.

It featured significant racing development, and featured a relocated intercooler, integrated roll cages, fully adjustable suspension, and four-piston 935 brake calipers. The 2.0l engine was heavily modified as well, producing no less than 375bhp and 299 lb/ft (405 Nm) of torque after receiving, among other things, a dry sump lubrication.

Combine that huge amount of grunt with a 930 Kg (2050 lbs), and you’ve got yourself a 924 that was good for 180mph (290kmh), and capable of sprinting from 0 to 100 Km/h in 4.7 seconds.

This particular unit is one of two car delivered to Japan from new where it covered only 109 Km on various track days in the first 7 year of ownership.

The ultimate incarnation of the 924 is currently offered for sale at Coys for an undisclosed price.
