Hi all may i start by saying im new on here and also new to Alfas and have purchased myself a 2008 147 ducati corse with some issues as I believe is to be expected Im not very mechanically minded but will have a good go myself to a point anyway i would love to get the car right it was a bad smaker with quite a heavy map so im told by the mapping guy i used here in wales anyway I wanted the original factory map put back on so he did successfully he informed me that the egr had been written out so now back online with the new factory map however it does now lack any low down torque but more to the point I think is the turbo whines really loud like there is a police car following me am I to asume the turbo is on the way out
OH all hoses are good
vac hose is sound
actuator moves well
it has a new egr
a new map sensor
but when pushed a little over 3 or 3.5k revs engine light comes on also this happened prior to factory map reinstalled and it said it was a boost issue i have found another turbo but its from a 150hp 147 would this fit on a 170 147
sorry for the longish thread but trying to paint the best pic i can any help would be greatly appreciated
kind regards Rob

To quote a mate in the turbo industry - "A turbocharger has exactly one moving part" Whistling turbo's can be as a result of tired "bearings" which are actually special brass bushes with the shaft spinning at insane speeds with a healthy oil supply. They take strain with hot shutdowns after driving hard, you should ideally let a turbo wind down to idle speed - even just 30 seconds of gentle driving prior to switch off is good. A slight whistle isn't ideal, but it's not a show stopper right now. Ask around the Subaru and Porsche guys as to who they recommend for turbo rebuilds & go there

Spark Plugs - Here's the NGK Plug spec for the 147's --> https://www.ngksparkplugs.co.za/?s=402

Engine light popping on - something is registering a fault code, probably something to do with the turbo or the EGR valve as it seems to be when you are boosting solidly at 3 - 3.5 rpm. You will need to get this onto a diagnostic reader that can read the 147 data
