Hello! First post on here, just looking for some advice really. My turbo has been making a whistle noise when sat at idle and revs to 1.5k. From what I have looked at online and about turbos, in general, it seems to be faulty. I have had it a year and the car is a 65 plate on 29,500 miles and only started to notice it over 2 months ago. The car still pulls really well and I don't notice any lag or loss of boost. Is this normal? What is the best route to take for this? I have looked at many places to have it possibly refurbish or go hybrid with it but really does cost a fair bit to have done. The next question is Would a turbo from say newer cars with the same engine a direct swap or would stuff need changing? (My turbo out and say at 17 plate one in) Just looking for a bit of help in this situation so any feedback is welcome!
