Following the cancellation of the P35 project in 1992, the car was briefly considered as a possible replacement for the NPT-90 in the IMSA GTP Championship, replacing the VRT35 V12 with the 3.0L turbocharged VG30 V6 that had previously been used. Wind tunnel tests were carried out on what was termed the 93GTP. However, Nissan was looking elsewhere and decided to pursue Indy Car racing. This lasted only briefly (though Indy Car concepts were beginning to be developed in the wind tunnel) and the realities of the widening recession hit home. This eventually led to the closing of NPTI in 1993.
