Nissan VRH engine
V8 gasoline engine family manufactured by Nissan
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).
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 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.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Nissan VRH engine”, the useful work is to connect “v8 gasoline engine family manufactured by Nissan” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Dec 22, 2025.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
