A turbo Focus is a great thing regardless of which motor it has in it!
Take into consideration how many miles are on your current car. Don't think I would put a turbo on a high mileage car.
Also think about when you'll need to go thru the CA emissions test with the 2001. I would hate to have to un-turbo then re-turbo my car in order to pass the e-test.
