I would also check to see if the turbo wheel has been rubbing on the comp cover and also check your vac / boost lines, like the map sensor lines and fuel pressure reg lines, 
 
Does your car have a ceramic turbo? if so it is also possible to snap a shaft, the front would spin freely but the turbine could be jammed also blocking the flow.
 
And check your cat converter, if you have the stock one they block up very easily, and that would also explain the lack of power and no boost due to the insane about of back pressure.
 
Last but not least do a compression test, if all your rings are gone then no compression > no load > no exhaust pressure > no boost. 
 
Is the car hard to start?

fixed!!!!! finally.
 
turns out the pins had come loose in the MAP sensor and werent connecting properly. >.<
 
 

ya very relieved lol
 
and i fixed the injector problem i was having so now it is running properly for the first time 3 months.... haha'
