The new Saab 2.3l turbo engines have a very small compact frame Mitsubishi
turbo that spools up almost as fast as you push your foot down on the gas.
It is very impressive.  It makes my Volvo turbo seems like it has a LOT of
turbo lag.  If my turbo ever dies, I'll replace it with one of these
smaller units.
