Yes, but only on certain generations and markets: the DC5 Integra Type R used a 2.0-liter K-series engine (K20A), and the US-market RSX Type-S—considered a successor to the Integra in the United States—used a K20A2. Earlier Integra generations relied on Honda’s B-series powertrains. So, the presence of a K20 depends on the specific model and market.
The K-Series era and the Integra
The Honda K-series engine family arrived in the early 2000s as a successor to the B-series, offering improvements in weight, efficiency, and high-rev performance. Within the Integra lineage, the K-series appeared only on late-era variants and in markets where the Integra name continued alongside related models.
Which Integra variants used K-series powertrains?
Below is a concise look at the variants most commonly associated with the K-series in relation to the Integra lineage. Note that market naming and availability varied by country.
- DC5 Integra Type R (Japan and many non-US markets) — 2.0L i-VTEC K20A engine, producing roughly 220 PS and revving to high redlines.
- US RSX Type-S (2002–2006) — 2.0L i-VTEC K20A2 engine; this model is often considered the US-market successor to the Integra line rather than an Integra itself.
- Earlier Integra generations (DA/DB/DC2; roughly 1989–2001 US timeline) — primarily used B-series engines (such as B16 and B18) and did not use K-series engines.
In summary, the K20 was not universal across the Integra's entire production run. It appeared in late-era, market-specific variants (notably the DC5 Type R in Japan) and in closely related models (the US RSX Type-S), while earlier Integras relied on B-series powerplants.
Market naming and model context
Market naming can be confusing: the DC5 used the Integra name in Japan, while the same platform was marketed as the RSX in the United States. The DC5 Integra Type R and the RSX Type-S share similar K-series architecture, but the official names differ by region and era.
Summary
The Integra did have a K-series engine, but only on specific variants. The DC5 Integra Type R in Japan used a K20A, and the US RSX Type-S used a K20A2. Earlier Integras (DA/DB/DC2) did not use K-series engines. If you’re researching a K-series Integra, you’re looking at late-generation, market-specific examples rather than the entire lineup.
