personally im going for a super charger from AA...8-9 LBS of bost is low enough to where im not to worried about the motor or trans being torn apart...but it still adds enough power to make the daily driver just that much more fun...also the whole kit comes with everything you need...though a bit costly...8,500...but comming with a cpu reflash which not only tells the cpu how to behave with the extra bost but removes the speed limiter...thats quite nice

turbos are amazing pieces of work...however...as with anything truly amazing it has problems and requires alot of work to keep it up...also...im not looking to get more then maybe...400-450 HP when im finished with my car...there is no more need for that in a daily driver...bare in mind torque is relitive to HP...increasing one in one way or another increases the other...to much torque will wind up killing you...on a wet day when your driving around and you sneeze and prod the gas just a little to much and the rear kicks out because you have so much torque in the car and you wind up in the trees with the birds...thats no fun...plus do you really want to worry every time you go to your car and start it up if your turbo is going to ware out? the bearings and turbines spin at such high speeds that its only a matter of time before something goes wrong...there is just no way around it...where as a twin screw super charger really is just...well...spinning only as fast as the motor needs it to since its driven off the motor...and its a simple fix to get more power out of it...change the pulleys...look at the ford GT...the stock one has 500 hp...change the pullys for the super...and it gets over 700...
