Toyota 1ZZ-FE specs: 1.8L (109 ci) 4-cylinder, 79 x 91.5 mm (3.1102 x 3.6024 in) bore and stroke, 10:1 compression. Rated 126-130 hp, 2003–2008.
The Toyota 1ZZ-FE is undersquare — the 3.6024" stroke exceeds the 3.1102" bore by 13.7% — a layout that trades peak RPM for leverage and torque low in the range. The 3.6024" stroke puts mean piston speed at 4,000 ft/min around 6,650 RPM, which is where a production bottom end is generally considered at its limit. Each of the 4 cylinders displaces 27.3 ci (447 cc).
10:1 is in the range that usually runs on pump premium.
6 factory variants share these dimensions, rated from 126 to 130 hp across 2003–2008.
