I considering getting an Aus DC5R but i want to convert it to japanese spec. What I would like to know is what did honda do to the Aus DC5R to reduce the compression/power?

This questions for Toda or anyone else who has an idea... If I was to use the k20a toda engine kit on an Aus spec DC5R would this end up producing the same amount of power as if I were to use the same kit on the JDM k20a?

Cheers.
