Nissan Z20 specs: 2.0L (119 ci) 4-cylinder, 85 x 86 mm (3.3465 x 3.3858 in) bore and stroke. Built 1984–1986. Used in the Nissan Datsun / Nissan Pickup.
The Nissan 119ci (Z20) is close to square: 3.3465" bore against 3.3858" stroke, within 1.2%, 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 4 cylinders displaces 29.8 ci (488 cc).
It is one of 3 engines in the Nissan 119ci family, all of them 119 ci — the differences between them are in compression, heads and rating, not displacement. 3 factory variants share these dimensions across 1984–1986.
