Turbo 2,5 DTi

With my Omega only from 2800 rpm comes really the pressure and since the turbo for long very strong whistle noises of itself, I therefore want to replace it precautionally. My question now, has someone still by chance a turbocharger of the 2.5 DTi lying around here, which is mechanically still completely intact ! Speak no cracks in the housing , no damage of the shovel blades or the shaft ?? I found a company to send the old part and this then General overtaken! Since this takes about 2 weeks, I wanted to have another turbo repaired and if I then have the new one, which would then be installed with me! So, if someone can help me and can sell me an old turbo (or borrow, because I could then send it mine), please report!
