Sr20 noise?

[E_Jay_Twenty]

Hey guys. So I just picked up this sr20 swapped s13. I'm hearing a noise form what sounds like keys jingling. That's the best way to describe it. So I took a video last night. You can hear the sound best around 31 seconds in. Sounds like it's coming from the turbo area. I also have a high flow cat that rattles but it's not the same sound and that only occurs around 2500 rpms. I'm going to pull the turbo hard pipe off (has an s15 turbo) and check for shaft play. Previous owner said the turbo only has 20k on it. Any other ideas what it could possibly be??

Bought the car last week and I'm just trying to get rid of the noises!
