On the 0-60 front for my Skyline, in practice it's more like 5.5 seconds, unless you're reving it to buggery, drop the clutch and red line it in 1st. I'm more inclined to keep my car in one piece and reduce my service interval!
As Dazzag said though, it's not really the 0-60 that does the business, in my opinion. It's the overtaking speed ranges 40-70 for backroads, or 60-100 on the motorway, for example. That's where I absolutely love my car. It never stops accelerating, and never lags (twin turbo means no turbo lag as its staged and turbos kick in from 3000rpm). 1st is a lunatic gear, but 2nd, 3rd and 4th all keep pulling and don't want to stop and 5th doesn't really hang around either.
When I've just joined a motorway, and I'm in the inside lane at 60-70, and I spot a gap to get into the middle lane, I am at 100 in the blink of an eye. Won't guess at figures, but in the time it takes for me to look from the right wing mirror, to pull out into the middle lane and to look down at the speedo, it's 100mph, with plenty more pull if I need it. That's where it's really useful and satisfying.
As for handling, unfortunately I still can't really comment. I have this fairly significant tracking/alignment problem with my front right wheel. Drives fine on the motorway, but lorry rutts and dips which give my front right more traction, knocks me about a bit. It's no way to drive a fast car. My steering wheel is a good 5 degrees to the right on the straight, so I'm getting that fixed next week. Then I'll start to get a feel for things.
Also, Skyline's are 4wd, but most of the power goes to the rear. The front wheel drive kicks-in when the back starts to step out (there is a front torque guage which spends most of its time on 0). At the moment, with my tracking problem, plus n00bness to the car, plus lack of wide enough round abouts (
) in my immediate area, I haven't pushed it hard enough to test the Hicas, or the front wheel drive torque split. Something I will have to learn later. All I've heard from other Skyline drivers is, just as you feel you're losing traction on the corner, the front wheel drive kicks in and it feels like you've got a tow rope on the nose, pulling you round the corner. Can't comment yet!

Same. For me, personally, they add more danger. I spent way too much time looking at my speedo, and potentially missing hazards in front of me, all because of the paranoia of speed cameras and cops. It's a double edged sword.
