Honda H Engine

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 80s and 90s, 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 CRX) for use in drag racing. The F20B is technically coded as part of the F-series family of engines; it is basically a 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 (2.2L) and H23 (2.3L). Both versions were using the same short block; different crankshafts and connecting rods were utilized to achieve displacement variation.

The H22 debuted in the U.S. in 1993 as the H22A1 for use in the Honda Prelude VTEC. Since then, versions of the H22 would become the Prelude's signature high-performance engine worldwide until the end of Prelude production in 2001. Variations were also used in the Honda Accords SiR in Japan and Honda Accord Type R in Europe. In 1994, Honda of Europe used the H22A cylinder head and the H22A engine block as the Formula 3 engine which was an H22A engine destroked from 2.2 liters to 2.0 liters (F3-2000cc) to compete in the European F3 series. It was then used by Mugen Motorsports as the F20B(MF204B) from 1997-2001. In 1995-1997, Honda of Europe used the same H22A-based F3 engine in the British Touring Car Championship (BTCC) Honda Accord. Also, in 1996-1997 Honda of Japan used the same H22A-based F3 engine in the Japan Touring Car Championship (JTCC) Honda Accord and won the JTCC for both years. Honda of Europe hired Neil Brown Engineering of England to convert the H22A engine into an F3 engine which would be later used in BTCC and JTCC.
