Toyota 2TR-FE specs: 2.7L (164.4 ci) 4-cylinder, 95 x 95 mm (3.7402 x 3.7402 in) bore and stroke. Rated 157-164 hp, 2005–2023. Used in the Toyota Tacoma.
The Toyota 2TR-FE is exactly square — 3.7402" bore and 3.7402" stroke are the same — which splits the difference between a high-revving layout and a torque layout. The 3.7402" stroke puts mean piston speed at 4,000 ft/min around 6,400 RPM, which is where a production bottom end is generally considered at its limit. Each of the 4 cylinders displaces 41.1 ci (674 cc).
It is one of 2 engines in the TR family, all of them 164.4 ci — the differences between them are in compression, heads and rating, not displacement. 20 factory variants share these dimensions, rated from 157 to 164 hp across 2005–2023.
