In what would become the final season of JSPC, Nissan would once again upgrade their cars into the R92CP.
 Nova Engineering retained their R91CK, while Team Le Mans would leave the series.
 Team Take One would take up their place with a former factory R91CP.
 For the 1992 season, the championship was actually divided into two classes, with the older Nissans running in C1, while cars which conformed with the 1992 World Sportscar Championship 3.5L engine specifications would run in C.  This meant that although Nissan would be competing against newer and faster cars, they would still be able to compete for victories against competitors in their class.

At the opening round at Suzuka, no C class cars would compete, leaving Nissan open to take the race victory in the R92CP's debut, with Jeff Krosnoff and Masahiko Kageyama replacing Anders Olofsson on the winning car's driver line-up.
 Nova's R91CK took second, ahead of a trio of new Toyota 92C-Vs.
 At the next round, the 1000 km Fuji, Mazda's Mazda MXR-01 C class car would show, yet suffer reliability problems.
 Problems for Toyota as well allowed Nissan to take the top four spots.

The next race at Fuji would once again go to Nissan, as Hoshino and Suzuki would beat the fastest Toyota by over a minute.
 This would be repeated at Sugo, although Nissan would manage to take that victory by a mere three seconds.
 However, Toyota would bring their C class competitor, the TS010 to the second 1000 km Fuji, and easily take the win over the second place R92CP.
 A second TS010 would join at the final round at Mine, but Nissan chose to bring their C class competitor to the event as well, the NP35.
 Even with five Nissans, they would not be able to overcome the Toyota challenge, as the TS010 once again took the win, leaving Nissans in second and third.
 Even with losing the final two rounds, Nissan was able to take the championship in their class, even though Toyota won the separate C class.
 Kazuyoshi Hoshino would take the solo drivers championship.
