Turbo

It is what ever the 'boneyard' can get. If you pull it your self, then it will be a lot cheaper. Are you getting any Check Engine Lights, because this car has sensors that will tell you, precisely, if the Turbo is not working correctly. It may just be a Boost valve, which can cost $15. It would be a shame to R&R a whole Turbo on a 1.8 liter ( not easy, I have done some ) to find out that the Turbo Charger was NOT the problem. (Food for thought)
