    metal vinration from new turbos?

    ok, so i just installed these new 19T-HL's. everything went great. I did notice the small bell that rest under the exhuast wheel was kind of loose. So, i checked the 19T-l chra i have and its basically the same, except the new one is very doorbell ish sounding when it spins. Every now and then at low rpms you here the small(bell) vibrate and sounds like that piece is just vibrating. Under higher rpms or boost nothing at all. Is this going to hurt my turbos? Never heard this before and car runs amazing and oil pressure is perfect. Any ideas? Kinda sounds like a piece of metal on an exhaust or something loose rattleing

    is it the heat shield behind the exhaust wheel? can you post pics of the part your talking about? I believe that should be on tight.

    Sounds like the heat shield. It supposed to be tight once the turbine housing is clamped on. If it's indeed rattling, you will want to fix it.
