I'm new to this site and i've been doing a lot of research on these L61 2.2 ecotec's. It seems as though every site I've been visiting has upgrades for only the cobalts up to 2006 or Ions up to 2006. Is there a difference between 06 and 07 Ions? and could i possibly use any upgraded parts, for example the 2.4 manifold swap for the cobalts onto a saturn ion?
