contributed to the team's success. The SOHC VG30ET was making upwards of , with a power band that extended from 4000 to 9000 rpm on a single turbo. From 1990 to 1995, Steve Millen drove the twin-turbo 300ZX for Clayton Cunningham Racing. The car dominated the IMSA in its GTO, then later GTS categories due to its newly designed chassis and engine. Millen would rank as the #1 Factory Driver for Nissan for 7 years and earn two IMSA GTS Driving Championships and two IMSA GTS Manufacturer's Championships. Among enthusiasts and the team themselves, the biggest triumph for the race Z32 was the victory in the 24 Hours of Daytona. In the same year at the 24 Hours of Le Mans, the 300ZX ranked first in the GTS-1 class and 5th overall. In an attempt to level the playing field in the GTS-1 class by reducing the allowable horsepower, the IMSA declared the twin turbo VG engine ineligible. The 1995 GTS 300ZX car would debut with the V8 Nissan VH engine at Daytona and would place first in the GTS-1 class at the 12 Hours of Sebring and Mosehead Grand Prix in Halifax. The JUN-BLITZ Bonneville Z32 holds the E/BMS class land speed record of set at the 1995 Bonneville Speed Trial. The vehicle was built as a partnership between JUN Auto and BLITZ. This record remains unbroken. In 1990, JUN's first Z32 went 339.2 km/h at their Yatabe test course and hit 373 km/h after some tuning at Bonneville. The 350Z replaced the Skyline GT-R and Silvia as the car for Nissan's factory and customer teams in the JGTC/Super GT's GT500 class and GT300 class respectively. The GT500 cars used were heavily modified and featured a longer nose and tail (requiring the production of the Type-E homologation special), carbon fiber bodywork, and a tube chassis. In 2004, Nismo won the GT500 championship. Until the 2007 season, the car was powered by a VQ30DETT V6. In order to increase competitiveness, however, a new 4.5L V8 powerplant has been developed. The 350Z, with slightly more pedestrian modifications also competes in the GT300 class (having started there even before the Skyline GT-Rs were replaced) by teams such as Endless Sports and Mola. In 2003 Hasemi Sports won the GT300 championship with the 350Z. In 2008 season, the 350Zs were all replaced by Nissan GT-Rs in the GT500 class, but they have continued
