After the turbo kit install and started motor for the first time, there's a noticable noise. Especially from inside the car. It sounds like a grrrrungh. Like something loose and scraping inside the motor. When I open the hood and try to listen to it, I can't really hear it. This is a B18c1. It seems to be coming from the area around the fpr. After driving for a bit, it goes away but will come back after startup. Having been to the dyno to get it tune yet, cause they are booked. Anyone with any ideas what it could be?
