What turbo is this?

[Mach1TaloN]

So I’ve had this car for 10 years, had it professionally tuned and everything. Now that I want to mod it further I need to know what I have to know how far I can go with it. For the longest time I believed this was a TDO6H 20G but I’m still unsure. Might be an 18G?
Perhaps you fine people have a better clue than me. Excuse the mess in there, I had a little fire and haven’t gotten the fire extinguisher powder cleaned out yet.

None of those numbers represent the 49179 on my compressor housing but it’s good info none the less.
