Hi Guys, I have a turbo with no markings on it. I'm trying to figure out what the sizing is of it. How would you suggest going about doing that? I've looked online in a couple places, but just gotten different answers and confused.

Any pictures? Any idea where it came from?
How large is the compressor wheel at the inlet? That's a start.
a set of digital calipers and measure the cold side air inlet and the exhaust inlet at the flange? that would be my first guess, but then again I know next to nothing about turbos, sooo....
Some one that frequents this board probably has rebuilt the exact turbo you have several hundred times in one of their previous lives. Post pictures and find your answer! (p.s. There is now way to upload pictures to GRM directly; upload them to flickr or picaso them use the camera button and insert the http link)
This MAY not lead you to an exact ID (although it usually can), but taking off the compressor and turbine housings and measuring the inner and outer diameter of each wheel will at least get you in the BALLPARK of how much power it can make and how it will spool on a given motor. And usually it can be ID'd that way as well.
Let's see some pics and some measurements! Compressor and turbine wheel size, housing opening size, etc etc etc..
It has a few T's on it so turbonetics is what it likely is. Here are your pics sorry it took so long I was out with she who must be obeyed.
Your link doesn't seem to work either. It could have something to do with the pictures not being published to the public. You might be better of using a different method to host them.
Fixed pics
Unfortunately you'll have to take off the housings or get some deep-reach inside diameter calipers to get measurements on the wheels themselves. The inlet and outlet are both tapered so measuring the 'mouth' of the housings doesn't give you the wheel measurements.
About all i can tell at this point is that it's a Garrett t4 design with what looks like a middle-of-the-range compressor wheel. I.e. not a 40 or 46 trim and not a t72, etc. Somewhere in the middle.
A more accurate guess would require more accurate measurements. What are you trying to put it on?
