There seems to be alot of question as to wether the a20's are interference or not, but we have had a few members on 3g's break there belts with no problems. But if you're gonna be that specific about the code, you might as well throw in the a20a1(carbed), and a20a5(euro, less emmisions). Internally they're almost identical.
