So the PT 7675 has a bigger compressor wheel but smaller exhaust turbine, and the BW 75/83 has a slightly smaller compressor wheel but the bigger exhaust turbine? Are they both dual ball bearing? Which one is newer?
I would assume that BW 75/83 is setup for more top end power while trying to keep spool time at a minimum by using the same size compressor wheel as the smaller exhaust housings.
