Audm Type R has the same engines as the us del RSX and Civic SI, that is the K20A2 (200hp), unlike the Jap spec K20A (220hp).

The K20Z (DC5S), is just an normal update of say the K20 engine. Therefore you would assume they would have tinkered with it to gain some torque/kw.

Without getting too much into it. The K20Z (DC5S) would probably have different cams, maybe not the K20A (JDM Type R) but would be very similar.

To have a fair comparison, you need to run both cars (DC5R/CD5S) back to back on same dyno, to get a true and fair comparison.

Hope that makes sense
