      Borg Warner will be a damn sight more reliable and durable, sacrifice little in terms of total power, and only will give way to a likely miniscule bump in transient response with drive pressures from an engine like that with even a decent cam in it. Those turbos are built substantially more robustly, I wouldn’t even consider them competitors in that arena having seen burst tests and failures firsthand.
