I would like to seee a larger photo of the engine, but from I THINK I can see:
*PCV looks like it goes to nowhere and does not have at least a filter on it

*EGR looks like it is eaither cracked at the base or was at one time
*The IAC hose has been replaced with something awful looking and I am not crazy about how sturdy it looks
*OEM heatshield is missing from above the turbo
*the brace for hte "hot pipe" that holds the BOV is also missing
*needs some stock ignition wires in there
*what on earth is the black thing above the X-bar behind the driver
None of these are huge deals, but they do add up.
As long as the car drives fine, boosts smoothly and does not overheat you are probably good to go. As for how long the turbo wil llast, no one can really say. IT depends on how it was used and how it was maintained.
