LOL...
no-one wants to be a statistic...
The additional rating will be due to the engine transplant catching up with you. Maybe your insurer considered a wheezy 2.0 with modifications to be less of a risk than a 3.0 in standard form.
My insurance hasn't changed noticeably, so it's hard to see the risk rating of the model has.
Yours is insured on a classic policy. Maybe it was under-rated previously and now values are stregthening, risk of payouts have gone up as well.
iirc, a few years ago, Pauls 24v was written off for a dented door and broken mirror. That's just not going to happen now.
Regarding 0-60 times, for the standing start auto's are held pedal to the metal and brake hard on...then GO!
I drove an S2 3.0 auto and at normal open road speeds it was no quicker to accelerate than a 2.1td manual. The go pedal had to be prodded pretty hard at times.
