Fiat 132 C2 040 specs: 2.0L (122 ci) 4-cylinder, 84 x 90 mm (3.3071 x 3.5433 in) bore and stroke, 8.1:1 compression. Built 1979–1980.
The Fiat 132 C2 040 is undersquare — the 3.5433" stroke exceeds the 3.3071" bore by 6.7% — a layout that trades peak RPM for leverage and torque low in the range. The 3.5433" stroke puts mean piston speed at 4,000 ft/min around 6,750 RPM, which is where a production bottom end is generally considered at its limit. Each of the 4 cylinders displaces 30.5 ci (500 cc).
8.1:1 is low by modern standards and generally happy on regular pump fuel.
It is one of 2 engines in the Fiat 122ci family, all of them 122 ci — the differences between them are in compression, heads and rating, not displacement. 2 factory variants share these dimensions across 1979–1980.
