Hp is one thing but the smile on your face will come from the torque that the turbo will generate.
Not sure how far into this you are but staying with the 3.08 gear may be a good idea, turbos like less gear than NA applications.
A very nice website that will answer any question you could possibly have is
http://www.turbomustangs.com/forums/ (don't let the word mustangs fool ya, its for all makes). Read the knowledge base and stickys before you ask questions.
Good luck
