Yes STS was recomending much smaller A/R housings. I remember one application I read about they were recomending .48 A/R turbine housing to V6 camaro guys, a group that normally runs .7 to .8 A/R turbine housings with T4/T3 hybrid turbos.

Do you know how much one of those after market Titanium wheels costs?
I started to look into it and when I got my first hint that it was over $400 I stopped looking.
It would be nice.
But I would have to see a compressor map first, I barely use the lower half of what that turbo compressor wheel can put out.

Yes they are.
Most of the GM 6.5L and 6.2L guys are picking used cummins take off turbos (removed for up grade, sold on ebay) and sticking them on our builds.
They leave the factory with great turbos.
Building one of our motors and sticking a GM factory GMx serries turbo on there is pretty much unherd of now.
They are usiing mostly HX35, HX40w, H1C1? and a few are HE351VE (the VGT scares off most people).
