Hey
Just picked up a Holset H1C turbo for $200 because it was missing the vband clamp for the compressor housing, brought it to a holset rebuilder to get the Vband clamp and he said it was in great condition.
Its a huge turbo, I'm still in the process of getting everything together, need to bring my stock manifold to a welder to cut a hole and install an external wastegate
(turbonetics 42mm) and also have him fab up a downpipe. That way I can get everything put together and installed as "one piece".
Anyway I read a few threads about these turbos, found out it has an 18cm^2 turbine housing from this:

But I couldn't find a topic where someone said "hey I am running an H1C, not an Hy and not an Hx series" I know that it is practically like an Hx35 since it had the 8 blade 54mm inducer.
Also a really nood question, but since it's a twin scroll, do I need to change out the turbine housing to a single from an Hx35?
I will be posting pics later tonight.
