Help with turbo

[dits145]

I have acquired a turbo that I need help identifying.
The P/N is 773540-5001S which indicates a GT3794, but the compressor doesn't seem to be the right size for that.
Compressor measurements: ind-67.7
exd-94.5

Turbine measurement: ind-72.4
exd-63.6

Any help on this would be appreciated!

Ok...can anyone maybe tell me what kind of driving this turbo would be best used for? Daily driving, towing, racing?

Couldn’t you get a 3794 from Danville with a 68mm comp wheel? Should be good for daily driving, towing.

I've already got this one. Would like to find out what it is comparable to and if it's one that would suit my needs

I think he’s saying it’s potentially a 68mm 3794.

Ok...I gotcha now. Thanks for the reply!

Did you ever think that it might actually BE a Danville custom 3794 turbo? Would be worth calling Mark and asking....

I did contact them. They said if it was one of theirs Danville would be on the wheel which I checked and it's not there.

Remove the compressor wheel see what the back indicates, there’s servers company’s that make a 67.7 turbo

I'll do that out of curiosity, but was really trying to find out what it is so I can get it properly tuned when/if I install it.
I just figured with the measurements someone would know what it is, or what it's comparable to.

You'll have to know which vanes are in it, and which turbine wheel it has also

Hopefully not something those idiots at Godspeed threw together

Thanks for the replies! I will be looking into it a little farther to see if there's a name on it. How can I tell what vanes are in it?

Post a picture. Stock vanes aren't a solid machined billet like the custom ones
