The second turbo that you posted has a different compressor cover on it with a different number. I just looked up that number and that number comes back being a BIG 16g. If the second pics under his PM is the one you have, then that is a 16g.

49178-01030 = 14b
49178-01420 = big 16g
49178-01460 = evo II 16g
49178-01470 = evo III 16g
