The K20Z in the FD is completely different to the DC5 Type S. The K20 in the DC5S is more similar to the JDM K20A in the DC5's than the K20A2 of the AUDM DC5R.
The K20 in the FD2 is running lower compression vs. the DC5S, FN2R etc etc.
DC5S: K20Z1 ~ 154kW @ 7400rpm
194Nm @ 7000rpm
FD2: K20Z2 ~ 114kW @ 6200rpm
188Nm @ 4200rpm
FN2R: K20Z4 ~ 148kW @ 7800rpm
193Nm @ 7300rpm
DC5R: K20A2 ~ 147kW @ 7400rpm
192Nm @ 6000rpm
EP3 would be putting out more kW than the DC5S with the JDM K20A.
