Actually, I think the stock water lines are really easy to work with. I can have them unbolted within 5 minutes and the turbo out of the car. The trick is to unbolt the water line from the block instead of the turbo. Install is pretty much the same.
The most difficult thing in my car to unbolt for taking the turbo off is the downpipe. It's just really hard to unbolt that damn thing for how I got things set up.
