In brief, the H22 is Honda’s 2.2-liter DOHC VTEC engine family, and it was used primarily in the Honda Prelude. A few regional variants existed, but other factory-installed Hondas did not come with the H22 from the factory. Enthusiasts frequently swap H22 units into other Hondas for performance builds.
Factory-installed H22 engines in Hondas
Below is a summary of the Honda Prelude applications and known regional variants where the H22 was used in factory configurations.
- Honda Prelude (2nd and 3rd generations) with 2.2L DOHC VTEC engines. JDM variants used H22A1/H22A2, while the US-market Prelude Type SH (1997–2001) commonly used the H22A4 in a VTEC layout.
The H22 family is most strongly associated with the Prelude lineage, where multiple regional variants exist. The Prelude SiR/SiR-T and Type SH names you’ll see in guides refer to these H22 installations in different markets.
Notes on the variants
Regional differences in engine codes (A1, A2, A4, etc.) reflect evolving tuning and emissions strategies. In the US, the Type SH Prelude is a well-documented example of an H22A4 installation, while JDM markets used H22A1 or H22A2 in other trim levels.
Non-factory H22 swaps in other Hondas
Many enthusiasts pursue H22 swaps in other Honda models because the engine offers strong 2.2L VTEC performance, but these are aftermarket projects rather than factory configurations. The following platforms are commonly pursued for H22 swapping, though results vary and require significant custom work.
- Honda Civic (late 1980s to early 2000s EK/EG/DC2 era) — a popular but challenging swap due to engine bay differences, required wiring, and mounting adapters.
- Honda Accord (early to mid-1990s through early 2000s) — some builds swap an H22 for increased torque and power, with custom mounts and exhaust/plumbing work.
- Honda CR-V (first-generation and early models) — occasional swaps for enthusiasts seeking a practical platform with extra power, typically involving substantial fabrication.
Swapping an H22 into non-Prelude Hondas is common in enthusiast circles but requires thorough planning, fabrication, and compatibility checks for engine mounts, transmission, ECU wiring, cooling, and exhaust systems. Always reference reputable guides and consider building codes and emissions requirements in your area.
Summary
The H22 engine family is best known for powering the Honda Prelude, with multiple regional variants such as H22A1, H22A2, and H22A4 used across different Prelude trims and markets. Other Hondas did not leave the factory with an H22, but many enthusiasts have successfully performed H22 swaps into Civics, Accords, and CR-Vs, turning these platforms into high-performance builds. If you’re tracking H22s for a project, start with Prelude documentation for authentic specs and then consult swap-focused communities for the target platform.
