The same engine also has a main page: Nissan VQ 10.3:1.
Infiniti VQ specs: 3.5L (213.6 ci) 6-cylinder, 95.5 x 81.4 mm (3.7598 x 3.2047 in) bore and stroke, 10.3:1 compression. Rated 255-298 hp. DOHC.
The Infiniti VQ is oversquare — the 3.7598" bore exceeds the 3.2047" stroke by 17.3% — a layout that favors airflow and RPM over leverage at the crank. The 3.2047" stroke does not reach 4,000 ft/min of mean piston speed until about 7,500 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 35.6 ci (583 cc).
10.3:1 on aluminum heads is in the range that usually runs on pump premium; aluminum sheds heat faster than iron, which makes the same number a little more forgiving.
It is one of 13 engines in the VQ family, sitting between the 121.9 ci and 243.9 ci members. 2 factory variants share these dimensions, rated from 255 to 298 hp. Factory fitments include the Infiniti G35, Infiniti FX35, Infiniti I35 and 5 others.
