Honda LEA specs: 1.5L (91.3 ci) 4-cylinder, 73 x 89.4 mm (2.8740 x 3.5197 in) bore and stroke. Rated 110-130 hp, 2011–2016. Used in the Honda CR-Z. DOHC.
The Honda L-series (LEA) is undersquare — the 3.5197" stroke exceeds the 2.874" bore by 18.3% — a layout that trades peak RPM for leverage and torque low in the range. The 3.5197" stroke puts mean piston speed at 4,000 ft/min around 6,800 RPM, which is where a production bottom end is generally considered at its limit. Each of the 4 cylinders displaces 22.8 ci (374 cc).
It is one of 8 engines in the L-series family, the largest at 91.3 ci. 10 factory variants share these dimensions, rated from 110 to 130 hp across 2011–2016.
