the h22a was introduced into production in 1992 with the JDM Prelude VTEC

the 99-01? accord euro-r came with the h22a7 equivalent to the prelude type-s motor with 200HP and 11-1 CR and red top valve cover.

the accord SIR-T came with the f20b (pre s2000 f20c) basically a 2.0 Liter De-Stroked h22a with the h22a VTEC head bolted on. Makes 200HP but slightly less TQ than a stock h22a.

the 99? accord SiR wagon came with the blue top h23a, 2.3 Liter DOHC VTEC, only made for 1 or 2 years.
