Used Turbo, Blowing Black Smoke

[Seb,]

I bought a stock turbo off a RB20DET it seemed in ok condition not much shaft play etc..

But after swaping it over into my r32 and taking it for a drive it wont go about 0 boost pressure and is blowing a hell of a lot of black smoke out the muffler.

I'm pretty sure its not oil burning because its not blue and it doesnt smell like oil, so i'm thinking that the turbo might be f*ked and is not letting air pass threw it probly so the motor is running rich.

Does anyone have any sergestions for what i should do, i dont know that much about turbo's and motors so maby i havent connected somthing up right, is there anything in particula i should check or do?

what sound does it make?

did you make sure that the wastegate actuator arm is connected to the wastegate flap?

if not, it will just stay open and you will get no boost.

who fitted the turbo?

I put it in myself thats why im thinking maby i dident do somthing right and maby somone can tell me what to look for.

I'm pretty sure i connected the waste gate arm up proply, looking at the old turbo and compairing it to the newer one the wastegate valve inside the turbo should be closed tight, As for the sound it wasent making any weird nosies to start with but is making a sound when im comming off the throttle a bit, anything else i could check?
