hi john. i wouldn't worry about the whistle for now because from what you said john, there aren't any other underlaying problems of which you would have said such as blue smoke etc pumping out the exhaust. seems like the bearings will be fine and the spindles, most of the problems from turbo whistling comes from a faulty vaccum line and as such would be identified by doing a vacuum pressure test. other less probable causes could be slight leaks in the intercooler piping on the side closest to the turbo. hope this helps

ktec pies in engine bay/quote]

It could be something to do with your pies in the engine bay :lol:

But back on subject it could be have something to do with the mods you've done which mean that you can now hear the turbo spooling thus giving the whistle.

When does the turbo whistle? All the time or around certain RPM range?

Will be a lot more audable with an open filter but still louder than standard with just a pannel filter. My old one with ktec pannel filter was much louder than my current standard one
