well, personally I'm STILL hot for the teacher

. You've got it right Nate. I read somewhere that the real top speed for our 2.2 is 105-108 mph. I think you are right - I'd keep it at about 80-85 mph for long hauls.
The Warden- I don't believe diesels HAVE a red line. they may have speed inhibitors, but no red line e.g. you cannot "blow'em up" by overrevving.
