Toyota 2ZR-FXE specs: 1.8L (109.7 ci) 4-cylinder, 80.5 x 88.3 mm (3.1693 x 3.4764 in) bore and stroke, 13:1 compression. Rated 121-138 hp, 2020–2026.
The Toyota 2ZR-FXE is undersquare — the 3.4764" stroke exceeds the 3.1693" bore by 8.8% — a layout that trades peak RPM for leverage and torque low in the range. The 3.4764" stroke puts mean piston speed at 4,000 ft/min around 6,900 RPM, which is where a production bottom end is generally considered at its limit. Each of the 4 cylinders displaces 27.4 ci (449 cc).
13:1 is high for a production gasoline engine; running a ratio like that on pump fuel depends on chamber design and fuel delivery rather than the number alone.
It is one of 4 engines in the ZR family, all of them 109.7 ci — the differences between them are in compression, heads and rating, not displacement. 7 factory variants share these dimensions, rated from 121 to 138 hp across 2020–2026.

Factory specification sheet.
| Bore/stroke character | 0.912 — undersquare — stroke exceeds bore, which favours low-end torque |
|---|---|
| Mean piston speed at 6,000 RPM | 3,476 ft/min — conservative for a street engine |
| Displacement per cylinder | 27.4 ci |
| Static compression | 13:1 — high enough that pump premium or better is normally required |
