I was in the same boat between Blower and turbo...
I was chatting my idea to my bro's tuner and the bad thing w/ a blower is the intake air temp. is so hot!!! The thing I liked about blowers is that it isn't too many parts pretty simple, and instant tq/hp!! But then that is pretty much it! DONE...later can swap out different pulley's for more boots, w/ turbo ya can run low boost for daily driving and crank it up some at the track and the intake air temp. w/ an intercooler is tons cooler, = not as harsh on the motor internals w/ heat. I am looking into a greddy kit, and I hear very little lag, so w/ auto-x I know ya need low end!!! Either way it will be a whole new animal to drive!!! I am going to turbo because you can build on it so much more and tuning wise....later when I get more serious can swap the turbo for a bigger one and you can always run higher boost, as long as your motor is ready for it!!!
Good luck!
I have two buddy's who have JRSC and it sounds like an indy car' that whine, they are both running mid-upper 13's little over 100mph w/ traction, not sure what a greddy around 10psi will do yet, still searching - I am drag racer so that is my direction...
