What is the difference between a k20a and a k20a2?

Answer 1

The K20A and K20A2 are both variants of Honda's K-series engine, but they differ primarily in performance and specifications. The K20A, found in the JDM Honda Integra Type R, produces around 220 horsepower and features a higher compression ratio, aggressive camshaft profile, and lighter components. In contrast, the K20A2, used in the US-spec Acura RSX Type S, delivers about 200 horsepower and has a slightly lower compression ratio and different tuning. These differences result in the K20A being more performance-oriented compared to the K20A2.
