These look to be roughly $2100-2300 turbos. Yes they add some bits over the equivalent Garrett that's around $1300-1400 sans turbine housing - but that still seems quite the premium for very very similar performance.
It seems it all comes down to the typical "power capability vs. spool" argument, and while there are small differences across manufacturers, it seems between the good ones that there is not much between them if you pick turbos of the same power capability.
I do wish Garrett would update their GT28/GT30 turbine wheels. I know it takes a while, but they're really under no pressure due to BW *STILL* having supply issues with their EFRs. Haven't they been "out" nearly half a decade now, and now have a crappy looking turbine housing to boost production numbers?
And no on the rough turbine housing not making a difference - you would ideally want it to be a mirror finish. It is amusing in that they really touted the turbine housing finish when they were trying to investment cast them, and kept pointing out the crappy finish on Garrett housings... then they come out with some stuff that looks worse than the average Garrett housing a little while later. hah
