So I'm driving down the road today, not beating on my car or anyhting and I notice a strange noise comming from my motor. At first I thought my downpipe was comming lose or something because it kind of sounded like metal rattling. So I turn off my radio and roll down my windows and noticed it's making the noise when my car turbo spools up. So I got aon the throttle a little and that's when I realized my turbo sounds like shit...

I don't know how to explain the noise but it sounds like my exhaust is rattling, but in my turbo. It's still spooling and I still get my power. I don't know about all of my power because I didn't want to beat on it. It's a Greddy turbo and I don't know the size, but I will find out shortly. I know I should know the size but I havn't gotten any of the specs from the original owner so please the last thing I need to hear is that I don't know shit about my car, I just need help. Thanks

The bearings in the turbo are probably going bad. Don't keep spooling it otherwise if the bearings get real bad, the center housing gets screwed up and the turbo can't be repaired.

Well it got alot worse and made it a whole lot easier to find the problem. My turbo , hopefully, is fine, but I think I have a hole or crack in my exhaust manifold. It's really freakin loud even at idle now. So I'm just gonna have it welded untill I can afford a new manifold, but I have to wait for my new gasket to arrive. Thanks to Tomei. oh and I found out the seller lied to me and I do not have a Greddy turbo, it's a Garrett AR60... I think that's a T3? Anyways I was wondering if they're any good.

before you jump to conclusion on your turbo being bad check the gasket that mates the turbo to the exhaust manifold. sometimes the bolts get loose and that gasket is made of metal and it starts rattling. and kinda makes a weird wislting noise also
