guessing its an s3? if so looking at 4 hours to remove the turbo first time mate, done from above and through the drivers wheel arch with the driveshaft out the way, one of my posts tells exactly how i done it. new turbo is around 600 quid, best off sourcing a reconditioned one but make sure its a genuine ko4 donning the blue tag as theres alot of chinese copys out there that arnt as good quality like mine! assuming it is actually your turbo off course.
