VNT turbo differences

[troopie]

I'm looking to get a brandnew VNT turbo from Impex-jp. Now when i look at the partnumbers, i should have 17201-17070, but they don't list that, only 17201-17050. After some searching both those numbers appear to be VNT turbos for a 1HDFTE.
Does anyone have the knowledge to know if those turbos really interchange?

TIA
Mark

I found this post with pictures, tldr: **50 was issued from '01 to '02 and the **70 – from '03 onwards. Completely interchangeable, but I couldn't find about how are they differing internally. Maybe the compressor/turbine wheels are different, but they both should be mechanically the same in terms of swapping.

Currently looking into putting a VNT/VGT onto my 12H-T with some simplified mechanical control over the geometry, that's why I found your question as I also stumbled on these two part numbers for the CT26V
