Infiniti VR30DDTT specs: 3.0L (182.9 ci) 6-cylinder, 86 x 86 mm (3.3858 x 3.3858 in) bore and stroke, 10.3:1 compression. Rated 300-400 hp, 2016–2024.
The Infiniti VR30DDTT is exactly square — 3.3858" bore and 3.3858" stroke are the same — which splits the difference between a high-revving layout and a torque layout. 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 30.5 ci (500 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 5 engines in the VG family, sitting between the 181 ci and 200 ci members. 18 factory variants share these dimensions, rated from 300 to 400 hp across 2016–2024.
