This is a dumb newbie question. I'm putting togther a turbo project. I got the turbo, it's a t04b/t3 . What I thought I ordered was an air cooled center section. What I'm speculating is ,it looks like I got is a water cooled section.
I see where the oil lines feed, but then there are 2 other holes which I'm not sure what do with?


Can someone please let me know how I can tell the difference between the two center section?

Also I ordered Corky Bell's Maximum Boost. Hopefully this might clear some other things up.

huh... never even knew there was such a thing as an air cooled center section(or is that just a center section without water cooling?). Well, if anything, a liquid cooled center section would be better I would think because liquids have a higher heat capacity than gases. My terminology might be a little off, but the liquids should get rid of the heat faster than a gas running through the center section. Think of it this way, pouring cold water over something vs. blowing cold air over it.
