is it tru that the clobalt has the same engine as an cavalier? if so does any one know what years. and would this application (http://www.turbokits.com/cavalier_turbo_kits.html) fit on a 05 LS. thanks for any feedback.

The engine is a 2.2L so it may very well be the same engine as the cavalier. As far as the application being able to fit or not all depends on how the engine bay is setup. The engine may be the same but depending where they put other components will determine if that will actually fit the same way as it would in a cavalier

i would just worry about mounting and things like that
