The Porsche 911 2.3 and 2.4 ST/GT cars were produced in 1970 and 1971. These were intended as racing cars and served as a replacement for the T/R that had been in limited production since 1968. The ST/GT ran in Group 4 competition and the FIA allowed Porsche to increase the bore and ultimate enlarge the engine. Displacement increased to 2247cc due to the 85mm bore and unchanged stroke of 66mm. Porsche dubbed these vehicles as the 911/20.

Porsche took the opportunity to enhance all areas of the engine. Biral cylinders, higher compression ratios, Mahle pistons, twin-plug heads, polished connecting rods and plastic intake trumpets were a few of the improvements. Horsepower jumped to an astonishing 240. The body material was exchanged for lightweight material and all non-essential interior items were removed. Alloy doors, hoods, bumpers and wheel arches were comprised of an exotic and ultra-thin fibre-glass material. When work was completed, the vehicles weighed just 850 kg.

For 1970 Porsche retained three of the cars as factory works vehicles. They were given chassis numbers 911 030 001, 911 030 002 and 911 030 003. An additional fifteen vehicles were created for privateers.

In 1971 Porsche continued to developed the agile racer. Displacement was increased, going from 2.3 to 2.4 liters. Weight was further reduced to 800kg. Using titanium and additional glassfiber components, weigh was lowered again to 789kg. The customer cars were given the 2.4liter engines that produced around 250 horsepower. There were about 12 examples produced. The factory cars were given an experimental 2395cc Type 911/21 engine that had an enlarged stroke of 70.4mm. Horsepower was reported to be around 260.

The example shown is an ex-factory works car. It was driven in the African Safari Rally.
