Toyota 5VZ-FE specs: 3.4L (206.1 ci) 6-cylinder, 93.5 x 82 mm (3.6811 x 3.2283 in) bore and stroke. Rated 183-190 hp, 1995–2004. Used in the Toyota Tacoma.
The Toyota 5VZ-FE is oversquare — the 3.6811" bore exceeds the 3.2283" stroke by 14.0% — 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 34.4 ci (563 cc).
It is one of 2 engines in the 5VZ family, all of them 206.1 ci — the differences between them are in compression, heads and rating, not displacement. 17 factory variants share these dimensions, rated from 183 to 190 hp across 1995–2004.
