Lets start with, that's not a 'T-3' flange, I dunno what it is but the T3, T-3, T03, whatever has a rectangular flange with a bolt hole in each corner. Unless you just gotta have that one, pass.
I see the Turbonetics logo on the Compressor housing, but nowhere else, he says it's a hybrid, evidently with a Turbonetics cold side (IF it has a turbonetics compressor, which you can't really tell from the pics).
What's with showing the turbo so that the cartridge is only upside down??? The tube with the braided hose in the middle and the two bolt flange on the end appears to be the oil drain hose, that would make the banjo fitting next to it a water fitting, so what's wrong with the oil feed or the other water port?
Maybe I've lead too sheltered a life but water cooling on a T-3 or a T-4 isn't particularly common, of course he says it's a hybrid (not specifically a T3/T4 hybrid), sooo hybrid what?
