...and I think we have a plan...
The primary issue with passenger-side fitment is due to the manifold-pipe not being able to move far enough inward toward the center of the car, due to interference with the side of the transmission where the pan bolts up to, and the floor of the car.
Here, you can see the back-side of the turbo, and at the upper-left, the pipe. There is a large space above the turbo, but it can't get in there because it hits the body rail to the right.
This roughly where it needs to go, ideally:
Although a more-rotated position such as this initially looked better, it would require more extensive piping modifications, and could be some issues getting the wastegate into position:
Removing the heat shield and clearancing the floor a little, it looks like the manifold pipe can be used mostly as-is, and the turbo can be both raised up like needed and put into a good position!
And, here is the manifold pipe and turbine housing, where it is getting close to where it can be and fit in place; the pipe bend is actually sitting above the transmission pan area, allowing it to move a little into the trans tunnel, which is where it needs to go:
Here's some experimental "body modification" to the floor to see if there can easily be enough room for the pipe, so that it sits above the pan area of the trans:
The w/g pipe is a significant issue here, as the flange on the end is what is hitting the body; and, there is really no room for the wastegate like that, unless more of the floor is "modified" as well.
I plan to make a minor change to the pipe (tilt the w/g pipe a little so the flange is at a better angle and the w/g can clear the floor), clean up the floor dinging, and see how it fits.
One of the transmission lines may need to be routed differently, but I won't know for sure until I make the other changes and get the turbo into place. The y-pipe cold-side may need some minor tweaking, and there's a plan to take care of that if needed.
