smog doesn't happen for the 02's till 06, is there going to be a problem passing smog with the K20a2 head on a k24 block? k20a2 in a civic si 02 will pass. k24 in a civic si 02 will pass smog... but will the hybrid? Is the emissions changed? has anyone tried going to a ref? I'm going with the N/A setup for the k20a2/24 long block setup. I want to get some good facts, if not i don't care... I'll keep the k20a3 for smog. Anyone have any answers?
