iv got a clicking or nocking noise after 4k or 5k rpm below that there is no noise im stumped on what it is this is my first dsm and first turbo car just wondering if its the turbo or a pulley or somthing like that please help
 
Without hearing the sound in person, my first guess would be your tensioner for your t-belt, unless you changed it or didnt adjust the pulley.
 
If you are running stock injectors, make sure you aren't running over 14-15 psi of boost. Do you have a logger to see what's going on? You are probably leaning out and knocking, but a logger would tell you. If you have a laptop, get a logger cable (about 35 bucks) and download tmolog.
