Rusty, the engine in my Cuda was not turboed, it had a fogger system. From my experience a nitrous slant will make more low end torque, and a turbo slant engine will make more upper end HP.
PS: I am not an expert on either system, and this is just my experience. In all probability a better matched turbo than I had would out perform the nitrous system, or at least could match the bottom end torque.
