From the C2SII cab to the 2.7 Boxster will be too much of a difference (read loss) in power, and you'll miss it.  If you are going for a Boxster, go for the 295bhp 3.4 S.  It's what I had before the C2S Coupe, and I loved every mile I drove in it!  Frankly, I think the 911 cab is too much of a compromise, and the Boxster trumps it for balance and even looks IMO since it is designed ground-up as a convertible.
