Honda H22/H22A

The Honda H engine was Honda's high-performance "big block" engine family from the 1990s and early 2000s. It is largely derived from the Honda F engine and shares many design features. It was replaced by the Honda K engine. The primary applications of the H engine series were the fourth- and fifth-generation Honda Prelude, and the fifth- and sixth-generation Honda Accord. 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 H22A debuted in 1993 for use in the Honda Prelude VTEC as the H22A1. Versions of the H22A would be the Prelude's signature high-performance engine worldwide until the end of Prelude production in 2001. It was also used in the 1994-1997 Honda Accord SiR and 1998-2002 Honda Accord Euro-R in Japan.
