Hi Leutz I would be interested in ALL the differences between the C18XE (1,8 16V 125PS) and the C20XE (2l 16v 150PS) … e.g. in the C18Xe I also have forged pistons and nitrate(?) filled valves and something like that …… And would I also have 150PS if I had an engine drilled to 2litres ???? Gruss Dennis
