    Blown stock turbo, not sure how/why it happened.

    A little background here just to get things started.

    I was driving back on the highway last Wednesday when I noticed that the 06 wrx was only hitting about 5psi of boost max. When I got home I did some test runs and it was happening in all gears. It would hit 5psi and hesitate to accelerate, no CELs or anything like that. I checked the boost lines and I checked the waste gate, both of those seemed fine as far as I could tell.

    I took it into the local dealership today and they just called back. They said they found metal flakes in the turbo and that it is completely shot. Thankfully it will be replaced under the power train warranty, but they can't provide any feedback as to why it happened. Is this something that just happens, or is there a larger problem that is going unfixed? They only "mods" I've got are a boost gauge and a SPT intake otherwise I'm stock.

    Thank for any help/insight.

    Sounds like your uppipe cat maybe got loose and went into the turbo. I would look at an aftermarket UP when you replace the turbo.

    Tek-Fox has a 06 WRX, so there is no uppipe cat.

    Edit : If there are metal flakes in the turbo it's likely caused by the compressor wheel hitting the housing.

    Carefully read the owner's manual with respect to the emissions warranty applicable in your state. The part may be covered.

    I still can't think of another place where the metal flakes might have come from. Unless your intake is using a crappy chrome plated plastic filter, hehe.

    Thanks for the replies. Sounds like its somewhat of an abnormal issue, should I just chalk it up to bad luck on my part and hopes that it doesn't happen on the next time around?

    Either way, after all the horror stories I hear about Subaru and their warranties, I'm glad it took 0 effort on my part to get it covered.

    Pretty sure there is a TSB for the 06-07 WRX's for the filter screen in the oil feed line causing turbo damage.

    That sounds like its the culprit, or at least plausible enough to give me peace of mind

    Thanks for all the help!
