Before I get hammered on the search tab, yes I did search and the only thing that was comin up was water/meth kits. So the turbo in question is on a Cummins generator and the on the tag instead of saying HX40 or HX50 and so on all it gave was a serial number and then Model H20. Does anyone have a clue what the specs on this would be or where I could find them. I'm trying to build a twins set on the cheap. Any help is really appreciated.
