Since this is an EFI car, a ball bearing turbo will work very well for street use as you can manage spark and fuel to get the turbo up quick. You still didn't give the volume of air you expect with your cam and mods, so it's difficult to say which turbo. For sure, call Garrett's distributors for their input.

The 964 is an excellent all-around cam that will do well for you. Another option is the GT2 cam profile since you are EFI - it responds better to good EFI tuning. Build your car around the cam first, then choose everything else (it controls the volume of air through the engine).

Good luck.
