take the turbo off, take it to a welder and tell him you want the hole beside the turbine discharge welded shut. simple as that. im not sure how you figured it was going to seal it off by doing what you did, theres still a 1/2" or so of dead air between the hole and the flange for your downpipe.

the whistling you're hearing is the turbo attempting to make boost. you also may want to check your plumbing for vacuum/boost leaks, make sure you dont have any nipples uncapped etc. take your time.
