Ok... before this goes any farther...
Mike owns a 2002 Stratus that apparently has the Mitsubishi made n/a 6g72 motor in it. Nate was simply commenting that he has only worked with the turbocharged mitsubishi motors, and doen't know much about the non-turbo ones. I hope everyone's on the same page now...
Mike, I don't know what to tell you either.... I've heard that some are better than others, but have no proof to back it up. I'd say look for a quality set of platnums or if you really get crazy iridiums...
