Turbo exhaust housing swap

[blacknight80]

This a long shot but I bet a turbo guru could give me some insight. Can I swap the exhaust housing from a Riviera turbo with a regal unit? Reason for asking is that I have a brand new riv turbo that appears to have the same compressor as a regal unit. Are the guts the same and have different exhaust housing?

I took things apart yesterday and measured everything and it matches up. I have to clock everything properly but the exhaust housing swap was a success.
