one more t810 chassis, (#3) would be constructed by lola, sold to japan but then sent to, and adapted by electramotive by the end of 1987. some of these cars actually shared their tub off of an earlier lola design, the t710, better known as the chevrolet corvette gtp. however, modifications to the cars would eventually extend to the point that electramotive would begin to construct their own chassis to replace the older cars, no longer relying on lola for the cockpit tubs. a total of five electramotive-built tubs were completed in 1988. electramotive later became nissan performance technology inc. (npti) in 1990, finally retiring the gtp zx-turbos once the new npt-90s were completed halfway through the season.
