where are you getting the a1 or a2? none of the real JDM honda engines have numbers at the end. i heard of a1 or a2 in countries in asia, europe, australia, or other countries with hondas, but have yet to see a1 or a2 from a real japan engine. there are many engine taken from other countries and claiming them as JDM.jspeczcturbo said:90-93 accord 2.0si-------F20A
