Optional alternative #2:
--Diverting the water lines that go to the throttle body to the turbo instead. The water lines that go through the throttle body are only meant for extremely cold conditions where it is possible for the throttle to get seized open or closed, the water running through the throttle body is meant to keep it warm. In theory, you should see horsepower gains from using this method since you are lowering the intake air temperatures. In reality however, the gains are minimal if even noticeable once the car has warmed up. This is an easy option, however if you live in a very cold environment I would steer away from this option.
