Most Honda H22A variants deliver roughly around 200 horsepower in stock form, with some Japanese-market versions offering a bit more. Exact figures depend on the specific variant, market, and year.
Overview of the H22 engine family
The H22 is a 2.2-liter inline-4 with DOHC and VTEC, part of Honda’s H-series. It powered a variety of 1990s and early-2000s models, most notably the Prelude, and is famed for its strong mid-range torque and responsive VTEC engagement. Horsepower varies by variant and market, reflecting tuning aims and emission regulations.
Key horsepower figures by variant
The following variants represent the most commonly referenced stock outputs for the H22 family. Note that exact numbers can vary by model year and market.
- H22A (Japan/other markets, 2.2L DOHC VTEC): about 200 PS (roughly 197 hp).
- H22A (US-market Prelude Type SH, late 1990s): about 200 hp (roughly 149 kW) in stock form.
- Higher-output Japanese-market variants (SiR/other calibrations): roughly 217–221 PS (about 214–218 hp) in certain iterations.
In short, the H22 family centers around a 200-horsepower baseline in most stock configurations, with a subset of market-specific variants delivering slightly more.
Performance context and what affects horsepower
Gasoline octane, intake and exhaust tuning, and the presence or absence of certain emission-control equipment can influence the rated horsepower. Worn or mismatched components, altitude, and ECU calibrations also affect real-world output. For enthusiasts considering swaps or mods, many upgrade paths target maintaining VTEC operation while maximizing airflow and fuel delivery to approach or surpass 200 horsepower in a tuned setup.
Why the numbers matter for drivers
Understanding the horsepower of an H22 helps in planning performance goals, maintenance, and potential upgrades. While the baseline is commonly cited around 200 hp, owners should identify their exact variant (for example, H22A1, H22A4, etc.) to confirm factory output and tailor upgrades accordingly.
Summary
The H22 engine family is centered on a 2.2-liter VTEC design with stock horsepower typically around 200 hp, while certain market-specific variants push output slightly higher into the 210s range. If you own or are considering an H22-powered car, check the exact engine variant and year to determine the precise horsepower figure and plan any performance upgrades accordingly.
