I guess you've thought of something that no one else ever has and you have a chip on your shoulder now?...a secret chip?



Alright...well we all know that the turbine a/r is 1.15 and a 10 blade wheel and we'll assume that that's a 3" flange on the housing....I don't have dimensions on different wheels in front of me, so I can't begine to guess there.



On the compressor side, I put a bill next to my housing and it's about the same size. We'll guess that it's 0.7 a/r. The inlet looks like 3" OD with say, 1/8" for the thickness and a taper down to the wheel of another 1/8" leaves us with about 2.675" at the inducer. That's about 68mm. You say it's a GT turbo...I don't konw dimensions of those though.



Maybe it's one of the gt40 compressor wheels?

well since I have a A/R 1.15 ex housing sitting here in my house on a T-70 A/R .84 compressor Turbo I would say that that compressor housing is a 4" inlet a/r .84 and it looks like it may be a big shaft and that limits what wheels you can put on it, but it's really hard to tell any of this from a pic. You can see the rough milling that was done on the compressor housing (isn't very smooth) for the new compressor wheel and I'm going to take a wild guess and say it started out as maybe a T66 or somthing around that size. ex wheel looks like it's a P-trim... All in all it doesn't look like anything you can't just go out and buy for a lot less off the shelf that will spool just as fast and make just as much power....
