I do agree that the B58 does have a better and larger turbo, but I've seen Dynojet runs of N55s making 430+whp with just some ethanol or meth. The N55 also has a HPFP to support gasoline and if you want a larger turbo, it's simply a Pure Stage 2 upgrade. The B58 is still the way to go if you want to make 430whp easily. The N55 requires a bit more work but still pretty easy.
