| - In the 1980s, Group C was where the most competitive GT racing occurred. Nissan engineers had the ideal engine for this class: a newly developed 3.5-liter twin turbocharged V-8. Their quandary was where to put this motor. It didn't take long to find an appropriate candidate. Dubbed the R89C, the race car was built upon a chassis co-developed by the British company, Lola. Nissan entered the R89C in the European World Championships, the American IMSA, the All Japan GT Championships and the 24 Hours of Le Mans. Nissan also worked on developing its own chassis based on the R89C. However, when the FIA revised vehicle regulations for Group C cars in 1990, prohibiting turbocharged engines from the field, the R89C's racing days in Europe and America were over. Nissan started development of a new Group C car for race series abroad, while the R89C continued its winning ways in Japan. This was because the All Japan Championship continued with the old group C regulations until the end of 1992. Therefore, the turbocharged engine continued, and the R92CP was born. The revised VRH35 engine produced more than 888 HP, with the Le Mans qualifying special generating 1200. The race car reached a maximum seed of 249 mph plus on the main straight at the Fuji Speedway. It generated more than 3.5 tons of downforce. The new race car was impressive indeed, winning all six All Japan Championship races it entered.
