It might be fun but, unless you fabricate the kit yourself, it is much more expensive to go turbo. Also for the power goal that he has in mind the turbo is a little overkill IMO since you would only have to spin it 6psi or so.

edit: What I mean is the additional up front cost for the turbo vs. the blower. The turbo would leave more room for growth but at 550rwhp it seems to me that the blower is a better value.
