I copied this off a european site. Only place I could actually find some data. FYI - these are normally used on diesel engines (trucks) but some guys are starting to use the HX/HY35 turbo's on their B-series for some decent 350+hp applications.
Turbo identification, trim & A.R sizes?, motor size?, expected Hp and Tq numbers? I'm guessing here but thats what it looks like
Holset H1D 47/55 -- 1.6-2.0 320 hv 774
Holset H1D 50/55 yes 1.6-2.5 340 hv 925

Looks like they're good for big HP numbers. Most don't even reach full spool till almost 4.5-5k rpms.
