R31 House built this 1988 Nissan Skyline GTS-X at their company in Japan. The factory turbocharged 2.0 L RB20DET inline-six was swapped for a turbocharged 2.5 L RB25DET inline-six from a Skyline R33 GTST. Behind the motor is a five-speed manual transmission and Z31 300ZX limited-slip differential. The car rides on Blitz ZZ-R adjustable coilovers and RS Watanabe 16-inch wheels with Yokohama A052 tires (225/45, 245/45). The factory HICAS rear-wheel-steering system was disabled. On the outside R31 House installed their front lip, skirts, and rear bumper. The car was repainted to metallic gray. The interior features Recaro seats, Momo steering wheel, and R31 House floor mats.
