Si shares the smaller, 2.0 liter, F 20 C version of this engine.
As the saying goes, "form follows function." I was recently reminded that this engine produced the highest specific power out of any normally aspirated gasoline engine for a decade or more until it was recently surpassed by the 4.5 liter V-8 in the Ferrari 458 Italia. The engine in my Civic Si is butter-smooth and an absolute joy to drive.
