The swap isn't worth it on a 2V. You need an adapter kit which runs something like $1500 - $1800. Blue the blower, and all the other random crap to support it. In the end, the gains aren't spectacular either.
You could acquire a used 2v procharger or vortech kit for the price of a used terminator blower plus parts to make it work. Probably with less trouble getting it to all work. I guess if you got a steal on the terminator blower it might make it a little more worth going that route.
you might want to also consider comparing the price of a new kb style blower new to the price of a used termi blower+supporting parts to make it work. It might not be that much more to just get a new 2v-ready one. They aren't cheap at all compared to the centrifugal 2v kits the last time i checked.
