Chronology
Predecessor Nissan VEJ30 engine

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.

The name "VRH" comes from the engines' V configuration ("V"), their purpose as racing engines ("R"), and the fact that all of them have eight cylinders (with "H" being the eighth letter of the Latin alphabet).[ citation needed ]

History

In 1987, Nissan began work on an engine exclusively for race use; the result was the VEJ30 engine, developed by Yoshikazu Ishikawa. This engine was based on old technology, and was not a success. For 1988, the VEJ30 was improved by Yoshimasa Hayashi and renamed the VRH30. Changes included increasing the displacement to 3.4 L (3,396 cc).

This engine was, however, still based on the obsolete VEJ30, and development of the all-new VRH35 [1] was started in parallel with the VRH30. In 1989, the VRH35 appeared as a new development engine and was used in the Nissan R89C.

A 3.0-litre variant of the VRH35Z was also used in the 1998 Courage-Nissan C51 at the 1998 24 Hours of Le Mans. Both C51s failed to finish. [2]

The design of the engine was later sold to McLaren, where it served as the basis of their M838T and M840T engines (which were used in all of McLaren's line-up since the McLaren MP4-12C). [3] [4]

Other VRH engines

The VRH34A and VRH34B are naturally aspirated engines used by Nissan in their GT-R Super GT race car from 2010.

The VRH34A is 3.4 L (3,396 cc) and produces 450–500 PS (331–368 kW; 444–493 bhp) and over 290 lb⋅ft (393 N⋅m) of torque.

The VRH34B is 3.4 L (3,396 cc) and produces 500–530 PS (368–390 kW; 493–523 bhp) and over 325 lb⋅ft (441 N⋅m) of torque.
