hi there, im wondering if any1 could give me any pointers what to try next..... recently changed bottom end on 98 wrx, all been sweet since, but ive started to get a strange kind off sqeel/shreeking noise when the turbo is spinning up....ive checked my front mount pipes all seem to be sealed,the bearing in turbo was nice and tight when we had it off 2 weeks ago.been going over bolts etc to make sure everything is snug,not sure what to do next.
ANY SUGGESTIONS? ? ?

Could be some debris or metal shavings from new bottom end got into the turbo via the oil feed

its quite hard to describe the kind off noise,cars being sold tomorrow so i was hoping it was just a wee air leak or something simple but im stumped... any other ideas? ?
