Yes (and they are made by Mitsu too) they are cast ni-resist and have the manifold, turbine housing, and internal wastegate flapper as one unit.
Ford did extensive research into what was best for turbo performance about a decade ago (I think) and they tested log style, tube style, and cast 'turbofolds' to see what yielded the best results. Ultimately there wasn't a whole lot of difference between the log and tubular versions, but the turbofold actually performed better for some reason.
Personally I like the small package they bring, but hate the limitations they have when it comes to upgrades....
