    Turbo Problems

    I was driving my 03 WRX the other day at about 70 mph, not pushing it much at all and all the sudden I notice my turbo is not spooling. I hear a kind of groaning sound in place of the sound of the turbo. I checked my oil, which was a little low, hoping that would fix the problem but still the same noise with no spool. The car still runs and idles fine. Where should I start? Any help would be greatly appreciated.

    Look for a broken vacuum line. Probably have a leak somewhere. What oil are you using?

    Check all of the intake tract as well as the vacuum lines that were already suggested.

    the up pipes on that year wrx i believe have a cat on them and the up pipes with cats have been know to foul up the turbo when peices of the cat break off and get jamed into the turbo. i would check the lines first but if the turbo is making a noise i would have it checked out.

    make sure your wastegate is still connected to the back of the turbo... my little clamp popped off once causing the wastegate to hang open and the car made no boost.
