hi all, i need some friendly advice on my turbo, i was just on the verge of putting my classic wrx inport on the market to up grade to a newage when my turbo started making a noise as i drive along, is allmost like a bearing drone. but the thing is it still runs fine with no missfire, no engine light on , i can still put the hammer down if i wanted and no smoke filling up the road behind me, if anyone has a clue what it could be i by them a nice cold drink at the next meet. and fingers crossed i be in my newage scoobe.
