yesterday night I heared something fall out of something in the differential region, and it started an awful noise
it's like a whistle that follows the speed, and it's present only when I apply torque (a little bit, a lot... didn't change)
About a couple mounths ago the same whistle started from the primary shaft of the gearbox, this noise follows rpm's...
What the hell it's happening?
From yesterday to today the diff noise is even worst

I'm seriously think to sell it...
Seems like it's a bad bearing.
The worst thing is that noone can change it.
Another bad thing: this turbo is too little.
Wastegate shut: 250+ kpa at 4000 rpm and down to 220 at redline.
No huge power gain compared to 200 kpa
