Okay, breakdown on models:
HY35w 2000-2002, looks similar to an HX35w, but has the 6cm housing.
HE341, aka; HY35w-D (or type d), has a 57mm(?) compressor wheel, fits 2003-2004 non-325hp engines.
This turbo looks similar to the HE351cw, with the forward aiming compressor outlet, but has a smaller compressor wheel and housing, as well as NO electric solenoid on the compressor housing.
HE351cw, has a 59.9mm compressor wheel, used on the 2004.5-2007 325hp in Dodge trucks.
HE351VE, aka; 351VGT, has a 59.9mm compressor wheel, with electronic-contolled "vane" ring and built in exhaust brake capability, used on 2007.5 through 2012 6.7s in Dodge trucks.
HE300VG, aka; 300g or 300vgt, used on 2013-2007 6.7s in Dodge trucks.
This is all from memory.
I could search out more particulars on the exhaust side dimensions, but that is pointless to me.
Mark.
