Hi all just wondering what is the minimum grade of fuel (95ron OR 91RON) that can be used on the z22yh in europe and uk? I ask because over here in Australia the astra mk5 equipped with a z22yh puts out 110kw and 210nm compared to 114kw and 220nm in uk. Im thinking this is because here in oz this engine was detuned to accept lower grade 91ron fuel thats sold here. This being the case that means all id need to do is swap the aussie ecu for a uk one to get the proper tune??? Ideally id want the lighter mk 4 asta but finding one in decent shape is getting so hard because of its age......so im looking at newer and more plentiful mk5 astas with z22yh engine but i want it with the same power as produced in UK because mk 5 astra is a heavier car and needs the extra horses........for some reason mark 5 astra with 2.2 direct didnt get sold in uk???
