I'm unsure of how recent this is, and it may even be a repost, but I was searching for information on modifying Ecotecs and I came across something that deserves exposure. The quality of images and detailing of the instructions are second-to-none and all direct from GM.

Primarily the focus is on souping up the Supercharged 2.0L Ecotec LSJ engine found in the Cobalt SS Supercharged and the Saturn Ion Red Line.
