i've driven 2k, and 2k01 G20's They read red at like 6700. This is the new redline for SR20's. They will become the Sentra base engine in a few years I believe. There are some fundamental changes in the latest SR20's. Look in recent issues of Sport Compact there was an article on the whole thing. But look for further taming/greening out to occur in future models. Nissan claims that they have strengthened the rest of the range to compensate. I can't testify to the validity of this. I know i'm pissed every time i hit the 7100 limit on my 200 though. Lousy fascists watering down my car!
