Toyota 3VZ-E specs: 3.0L (180.5 ci) 6-cylinder, 87.5 x 82 mm (3.4449 x 3.2283 in) bore and stroke. SOHC. Rod ratio and piston speed worked out.
The Toyota 3VZ-E is oversquare — the 3.4449" bore exceeds the 3.2283" stroke by 6.7% — a layout that favors airflow and RPM over leverage at the crank. The 3.2283" stroke does not reach 4,000 ft/min of mean piston speed until about 7,450 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 30.1 ci (493 cc).
It is one of 2 engines in the 3VZ family, all of them 180.5 ci — the differences between them are in compression, heads and rating, not displacement.
