Nissan VQ30DE-K specs: 3.0L (182 ci) 6-cylinder, 93 x 73.3 mm (3.6614 x 2.8858 in) bore and stroke. Rated 222 hp, 2000–2001. Used in the Nissan Maxima. DOHC.
The Nissan VQ30DE-K is oversquare — the 3.6614" bore exceeds the 2.8858" stroke by 26.9% — a layout that favors airflow and RPM over leverage at the crank. The 2.8858" stroke does not reach 4,000 ft/min of mean piston speed until about 8,300 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 30.3 ci (497 cc).
It is one of 19 engines in the VQ family, sitting between the 121.9 ci and 243.8 ci members. 2 factory variants share these dimensions, rated at 222 hp across 2000–2001.
