The Nissan R90C was a platform used for Group C racing cars built in 1990 by Nissan Motors for competition in World Sportscar Championship (WSC) based in Europe and the All Japan Sports Prototype Championship (JSPC). The cars based on the basic R90C platform would compete until 1993 before Nissan chose to withdraw from sports car racing, not returning until 1997. It won three JSPC championships and several significant endurance races during its career.

The Nissan VRH engine family consists of several racing engines built by Nissan Motor Company beginning in the late 1980s. All VRH engines are in a V8 configuration, with either natural aspiration or forced induction. Some VRH engines are loosely based on Nissan's production V8 engine blocks, including the VH and VK engines, while others were designed from the ground up for racing and share no components with production blocks.
