Turbo 440 duster

Here's another question for ya: How come the intake comes off the turbo to the engine from the driver's side in the first picture, but goes in from the passenger side on the last picture?

The first pic is how I have the cold side running now, because I plan of running the water injection, was going to run an air/water cooler in older pic and changed my mind.

This turbo is capable of 1k HP , My goal is 7-800 rwhp , and I think it is possible but I went turbo because of it being a street car . The turbo engines like more highway friendly gears like 3.23-3.55. Need that load of that gear to make the turbo work right.And they like street friendly cams and can produce high HP and decent gas mileage on pump gas. Here is an example of a super steetable turbo mopar on pump gas
