I have read a few posts on Turbo problems and damaged Turbos and am not sure about mine? I had my battery replaced last Tuesday and the auto-elec noticed that my coldair intake pipe below the battery was off. He put in back on and secured the clamp. I was amazed how much more boost I gained, I bought my BA MkII XR6T 6SPD Man as an ex factory executive car and would guess that pipe has been off or loose since I got it. Its now done 80,000KMS Yesterday a bad vibration started when the turbo kicks in, it has since got less and less but is still there under acceleration, I have also lost that boost I had gained and more. I had a good look under the bonnet and cant see any pipes loose, the turbo sounds fine and there is no knocking sound? I am wondering if this extra boost has fried something or a blocked injector, faulty plug under load? I always use VPower from the same servo and have filled the tank today. I will be calling my mechanic tomorrow but I though I would ask for ideas? After reading posts, if the worst has happened then where can I get my Turbo fixed or replace in the Rowville area by someone that will do a good job at a fair price? Thoughts please?
