Toyota 2JZ-GTE specs: 3.0L (183 ci) 6-cylinder, 86 x 86 mm (3.3858 x 3.3858 in) bore and stroke. Rated 320 hp, 1993–1998. Used in the Toyota Supra. DOHC.
The Toyota 2JZ-GTE 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).
It is one of 6 engines in the 2JZ family, all of them 183 ci — the differences between them are in compression, heads and rating, not displacement. 6 factory variants share these dimensions, rated at 320 hp across 1993–1998.
