help ID Holset Turbo?

[mini612]

Just need some one to help me decide if this is an hx35 or H1c? And yes it would be better if we get measurements but I don’t have that info at this time. I know it’s an 8 blade. Looks old and needs a rebuild forsure.

It is a H1 series for sure and not an HX35. HX35 turbos never had a separate backing plate or used a v-band clamp on the compressor cover. Hope that helps.

Thanks for your input. Anyone else?

I think that is a h1c from an early cummins engine.

Info here: http://dodgeram.org/tech/dsl/FAQ/turbo_faq.htm

That site has some casting numbers that were on the turbine housings- see if yours matches since we cant read it in the photos.

There's some great info in that link above.
