Without knowing the noise i'll give you a couple of scenarios:

A/ If the turbo was you received was not clocked correctly theres a good chance the either the exhaust inlet is not tight or the intake pipe in not aligned prperly causing a leak.

B/ If the turbo is a bush baring have they drilled out the oil feel banjo from the block?

C/ Did they run a flush through the engine first as these cars if not serviced properly can have bad oil feed problems? I gather you did put new oil in?

D/ The turbo has not been built properly so the wheels are rubbing against the housing.

If the waste gate is not working properly it wont make a noise......it will however either generate boost at WOT towards the end of the rev limit or will develop to much boost.

P.S. Regardless......all of the above means the turbo will have to come back off.

Free spinning turbo. Just as I turn off the car I can still hear the fan of the turbo spinning

Loud clunk noise when coming off boost....

If you can hear the turbo spinning after it's shut down; that's a good thing. Well balanced, good cartridge.

As for the clunk; not so sure. Wastegate snapping shut, bov opening?

      just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.

      My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.

      To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
