I looked at the first post again and was thinking about how Borg Warner had moved towards extended tip technology (more exducer on the compressor) in the last decade. The billet wheels would seem to change some trim requirements since the total area is slightly increased when the center of the wheel is more opened up to airflow. The Comp Turbo here seems to have a smaller exducer then I would expect in previous generations of turbos. Side note, lots of people are making crazy power with compressor inlet restrictions by running a huge exducer compressor wheel that is cut down to have a small inlet. So when your turbo is actually matched up properly, power should be much easier to extract.
