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.

 

You can always get one of those fancy tools and measure the wheels to see what you're working with. With enough fabbing, you can probably make anything work

Looked it up. You sure its not an HX20? Says it was used in light duty commercial engine applications up to 4 liters of displacement (so about 240ci).

www.cummins.com/turbos - Holset HX20-25-27

If so, its going to be smaller than your stock HX35. I believe the bigger the number, the bigger the turbo on this series of Holsets.

 

No, I've actually found out that it's not a zero. That zero is a D. Apparently they put a slash mark / through the zeros on the stamps so you can tell the difference. It's actually a H2D. I searched that one and found some info, but not much. I would measure, but I don't have one of those fancy tools.

 

I found anywhere from a 62-66 on the compressor and 77-78 on the turbine. Exhaust housing is about 25cm or so.

 

Oh wow, that's a big *** exhaust housing. I wonder it that could be modified?
