I don’t doubt that the Gen 3 is better than the 2R, etc. but the Gen 2R is still a great unit! I had one on my last Coyote. It made 840rw and didn’t seem to loose it’s breath at 8,500 rpm. The little thing ripped! OP, if you find a good deal on a used 2R, I wouldn’t hesitate. Especially for a bolt on street car.
