so a bit after i turbo'ed my eg hatch. ive noticed the trans? making some really loud grinding noises which is making the whole car vibrate. its under certain rpms (mainly higher) and its when the car is accelerating and decelerating. it also makes a squeeking noise as if it sound like a belt, but once again all happened at once.

im guessing either bad motor mount? axle? trans?

plz help
