Toyota 7A-FE specs: 1.8L (107.5 ci) 4-cylinder, 81 x 85.5 mm (3.1890 x 3.3661 in) bore and stroke, 9.5:1 compression. Rated 105-115 hp, 1993–1997.
The Toyota 7A-FE is undersquare — the 3.3661" stroke exceeds the 3.189" bore by 5.3% — a layout that trades peak RPM for leverage and torque low in the range. The 3.3661" stroke does not reach 4,000 ft/min of mean piston speed until about 7,150 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 4 cylinders displaces 26.9 ci (440 cc).
9.5:1 is in the range that usually runs on pump premium.
It is one of 10 engines in the A-series family, the largest at 107.5 ci. 9 factory variants share these dimensions, rated from 105 to 115 hp across 1993–1997.
