A little extra tq down low almost always helps. There are people changing the engine from a 1.3 to a 1.6L in the festiva/aspire (same engine design) and report almost no change. If I choose to rebuild an older engine I would like to think the new tolerances are a lil better, and would opt for some polishing on the components to reduce friction. that way you can have your mpg's under 3000rpms, and a little more fun above that mark when you choose.
