The Honda H engine was Honda's larger high-performance engine family from the 1990s and early 2000s. It is largely derived from the Honda F engine with which it shares many design features. Like Honda's other 4-cylinder families of the 1980s and 1990s, It has also enjoyed some success as a racing engine, forming the basis of Honda's touring car racing engines for many years, and being installed in lightweight chassis (such as the Honda CR-X) for use in drag racing. The F20B is a part of the F-series family of engines; it is basically a cast-iron sleeved down destroked version of the H22A. It was developed by Honda to be able to enter into the 2-liter class of international racing.

H-Series consisted of two different displacements; H22 2.2 L (2,157 cc) and H23 2.3 L (2,259 cc). Both versions were using the same block; different crankshafts and connecting rods were utilized to achieve displacement variation.[1]
