Hello,
3 months ago my gt2560r failed at a low pressure, All of a sudden the turbo started to make a terrible noise and the compressor wheel couldnt move freely enough. 3 days later turbo started to smoke like crazy.
Now my gt2871r has the exact same failure. The strange thing is that the failure occured during low boost again.
I run a 0.050 oil restrictor. I cannot determine if this is the problem , or an instant high egt. Something else, is it possible to fail due to boost leak?
Any ideas are welcome.

The last work I did before the failure was to change a broken stud on the manifold . Had to disassemble the turbo.
I'm getting the oil from a port next to the oil filter. I'm not sure about the size of the line but you can see it in the picture.

Just looks like a lot of sharp bends to me. probably not much of an issue with the feed given the pressure, I loved my 1.6 and having the feed port right there on the hot side. how/where is your drain running?

Im gonna say you dont need a restrictor with the banjo there, since they usual act as a bit of a restriction, not to mention the fact that the turbo may already have a restrictor as others pointed out
hows the drain?
