Well, just an update... the turbo is blown. Less than 2 hours after purchasing the vehicle.
Between that an the other maintenance the orignal owner neglected, I'm looking at 2 grand for an import shop to get her a new turbo and back to new condition. All in all, not too bad since I got such a good deal on the car, but still a kick in the balls.
Off to search for a VF46 to replace the VF40, right?
