Except for the giant lag below 3.5K because you put a bigger turbo that's harder to spin, bigger intercooler with more volume to fill, and so on. MB, BMW and others are doing a lot to eliminate this from new cars, so that you get torque down low and so they don't drive like "the widowmaker", but I wouldn't equate those old turbo engines with the new stuff. Yes, both turbo, but delivery is hugely different, which is important. Torque beneath the curve is what makes that F80 so good. A 600hp 2.0L that has to be revved up to 4K to start making power because you put a GT40R on there is not the same thing.
