What kind of turbo are you running, and at what rpm are you hitting boost at?  Where in the rpm range are you hitting max boost and max torque? What size tire do you run for the strip? Are you going to run something like a welded diff?  Strictly track?  That info could make the difference in what gets recomended.  Mid 14's are pretty darn good.
