Turbochargers are specified based on flow rates. 300 hp is 300 hp, regardless if its attached to a Honda or a Peterbuilt. It's not quite that simple when you get into pressure maps and what not, but people shopping the scrapyard for Powerstroke turbos to boost their budget projects aren't usually too fussy.

The old '90 International 466 I drove way back was only rated at 250hp if I remember right. That figure is nothing special for a gas four-banger 1/4 the displacement these days.
