Snaged a new motor today and the previous owner gave me his DIY mani/dp and since the funds are kinda tight i was thinking of just using what i have. Savington brought up a good point about how the OEM header was not made to hold the weight of a turbo, and this DIY mani is clearly made out of parts of the OEM header.
Take a look:




How might i make this thing last a while?

dude... this manifold looks SICK!
you need to weld bracket that goes from turbo inlet flange to a "head" flange. any muffler shop will charge you around $40 to do so.

no...The manifold is supported by seven inches of 3/4" Aluminum Rod.
I think the brace needs to run from the turbo flange down to the block, or the motor mount. Both dvcn and I have SSAutochrome manifolds braces that way and they're surviving. I'm using some round mild steel rod. It does a nice job of supporting while having some give for expansion/contraction. I originally went with square tube, but it eventually tore. So I sectioning the square and welded up some solid rod in the center.
