I’ve got a strange rattling noise coming from the turbo area that is very noticeable if you put your ear to the air filter. Afraid it’s coming from the turbo, but it’s not leaking or smoking at the moment. Started last night. Drove it to a buddies house last night and when I got it the car to leave that’s when I noticed it. Attaching a video. Let me know what you guys think pls. Car is a 93 180sx with a red top sr20det. I recently had a new manifold installed because the old one was cracked but it was fine for about a month. Any help would be greatly appreciated!

Also want to add, I’ve experienced no noticeable loss of power. Engine seems to be running very healthy other than that noise

Can you pop the filter off and look in the housing to see if there's so much shaft play you're starting to hit the compressor housing? You could also gently wiggle everything around and see if its loosey goosey.
