Nissan VQ37VHR specs: 3.7L (225.8 ci) 6-cylinder, 95.5 x 86 mm (3.7598 x 3.3858 in) bore and stroke. Rated 332-350 hp, 2009–2020. Used in the Nissan Z. DOHC.
The Nissan VQ37VHR is oversquare — the 3.7598" bore exceeds the 3.3858" stroke by 11.0% — a layout that favors airflow and RPM over leverage at the crank. The 3.3858" stroke does not reach 4,000 ft/min of mean piston speed until about 7,100 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 37.6 ci (617 cc).
It is one of 14 engines in the VQ family, sitting between the 121.9 ci and 243.8 ci members. 24 factory variants share these dimensions, rated from 332 to 350 hp across 2009–2020.
