Honda H engine
The Honda H engine was Honda's 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 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 F20B, though technically coded part of the F-series family of engines, was basically a destroked version of the H22A. It was developed for Honda to be able to enter into the 2-liter class in racing.

[edit] H22A
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 1998–2003 Honda Accord Euro-R in Japan and Accord Type-R in the UK and Europe (however different camshafts and a different intake manifold were used in the Euro R H22A). The H22A in the Prelude Type-S, CH6 Type-R and CL1 Euro-R came with the trademark red crinkle finish valve cover. It is known that Honda in accordance with Hondata and Mugen specially designed a H22A1 engined de-stroked to 2.0 liters, in order to meet standards for the Bonneville Flats race, this engine achieved an acclaimed top 1,743 wheel horsepower in a Dynojet, with nothing more than special methods of port and polish to the head, ports and insides of the engine, a more aggressive camshaft play with wider special cut intake inlets and exhaust outlets, along with 8 750cc injectors controlled by a Hondata computer, it also contained a GT60RR, with a .75 A/R, turbocharger set at 25psi, and a specialized intake manifold with an electronic throttle, all mods fumes going down a specially designed straight 5" side exit exhaust. Reports say that the build of the engine was an estimated $25,000 investment, and the engine needed no repairs, nor change of parts through all of it's competitions, something incredibly unusual for this type of competition were engines have to be verified and possibly rechecked after every race, it is one of only three cars to ever have achieved this in this competitions, the other being Hondata's Civic Si EK9, and J's Performance Civic SiR EG6.
