The previous Nissan R89Cs were run by the European team. A lone JSPC R90CP was run by the Japanese team but did not finish. By the second round of the season at Monza, the first three R90CK chassis were completed with Northern Ireland's Kenny Acheson and Brits Julian Bailey and Mark Blundell joining Italian Gianfranco Brancatelli in the driving line-up. Although both cars ran well, one car would not have enough fuel to reach the end of the race. The second car would finish seventh. Both cars ran towards the top of the field at Silverstone before a suspension failure and fuel problems eliminated both cars in the final few laps. The team would finally see some success at Circuit de Spa-Francorchamps, with both cars finishing and the Acheson-Bailey car taking third place, two minutes behind the winning Mercedes-Benz. The driver line-ups were switched for Dijon, and the new Bailey-Blundell duo took a podium. Although the Nissans would not win podiums at the Nürburgring, the team finished both cars in the top ten for the first time. As the season went on, the team continued to improve. At Donington Park, both cars finish in the top six, with Acheson and Brancatelli finishing fourth following the post-race disqualification of both Jaguars. At the fly-away round at Montreal, the R90CKs would take their best finish so far that season with a second-place finish. The race was stopped early due to dangerous conditions, but Bailey and Blundell were running only six seconds behind the leading Mercedes-Benz when the red flag was shown, with the second car Nissan finishing fifth. The good results for the team continued into the final round of the season at Mexico City with Bailey and Blundell taking second place once again, although this time two laps behind the winning Mercedes-Benz. Acheson and Brancatelli finished fourth place. In the team championship, Nissan finished third, four points behind Jaguar. Bailey was the highest ranking Nissan driver in the driver's championship, finishing in ninth place. Following the season, Nissan chose to leave the World Sportscar Championship and concentrate on the JSPC and its efforts in the IMSA GT Championship in North America. Nissans only competed one other time before the World Sportscar Championship was abandoned after 1992, with Nova Engineering's R91CK running in an invitational class at the 1992 1000km of Suzuka, finishing in fourth place.
