Toyota 3VZ-FE specs: 3.0L (180.5 ci) 6-cylinder, 87.5 x 82 mm (3.4449 x 3.2283 in) bore and stroke, 9.6:1 compression. Rated 185 hp, 1992–1993.
The Toyota 3VZ-FE 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).
9.6:1 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 3 engines in the 3VZ family, all of them 180.5 ci — the differences between them are in compression, heads and rating, not displacement. 2 factory variants share these dimensions, rated at 185 hp across 1992–1993.
