I have removed the section of duct work between the air filter and the turbo, and replaced it with a pvc contraption I madeup. I was slow at work. what can I say?? What I did was cut a piece of 4" PVC pipe, and glue inbetween 2 PVC Female adapters. Worked like a charm, now I can hear the turbo wind up, it has been inplace for about a week now, the heat shield is doing it's job. the PVC has not melted. If you would like pictures let me know, and I will get some.
