Default HP76 Turbo

I have a turbo and it has HP76 stamped on the backplate. I was wondering if it could have anything other than an F1 turbine wheel on it? It is a ball bearing turbo, but I haven't measured the exhaust diameters yet.

Default HP76 Turbo

It's possible it could have an older turbine wheel. If you can post the wheel measurements I can tell you for sure

Also can you tell me what type of housing is with these numbers cast on it 20838-81 96

Finally, can you let me know if an S-trim housing will fit the F1-68mm wheel

Is the dimensions above an F1-68mm turbine wheel? What about the tangential housing p/n?

The part number you listed doesn't turn up in any part number I've found. The dimensions of the F1-68 are

Exducer 2.677 Major 3.11

The .96 A/R tangential undivided housing part number for the F1-68 is: F1-68 Tangential Undivided with vband 21595-68 without v band 21715-68

So the turbine wheel I have is definitely an F1-68mm based on the dimensions I provided? What would those casting numbers be? Could a Q-trim housing fit on an F1 wheel?

Would an S-trim housing fit that turbine?

I sold the housing with those p/n to someone else, I was told it was a .81 A/R housing with an F1-68mm turbine. I purchased an S-trim "on-Center" housing that has no numbering on it, except for a .96 on the inlet. Can I measure something and determine A/R?

I don't know what the casting numbers mean. they don't have a number that I can find in any catalog back to 2007. They aren't Q trim numbers wither.
