As far as ease of installation, the blower is by far going to be less of a hassle and the blower will come in a little cheaper than the turbo.
Both make great power, but the turbo has the edge. As far as turbo kits, there are a few that have come and gone. I believe that Pro Turbo Kits are the latest and greatest.......around $3500. I don't personally know much about them, other that what I read.
I've had two centrifugal blowers and I personally prefer them to a roots style as the will make more power up top.
So it still will come down to what you want. If you want to be different, go the turbo route.....there are fewer of those out there. A roots style blower is also not used at much.
Otherwise, be like the rest of us and go with a centrifugal blower and the usual boltons....tried and true.
Anyway you spin it, your going to make considerably more power, and can't really go wrong doing it any of those ways.
