Yeah that is pretty silly.
I might be wrong, but the piping also doesn't seem right?
It doesn't look like a twin TB setup... but so many pipes leading to that back area...
Considering all turbo jobs on the FTOs are a custom job, it can come in many different shapes and forms. There's nothing to say that the setup there doesn't work.
However saying that, he is going to have a huge amount of lag with the intercooler setup like that
There are two types of people on forums; those that give helpful advice, and the others
I think what happened is the guy must've used the wrong mount turbo (L/R) and hence now the charged air needs to go over the motor from the front bank to the intercooler rather than if it exited from the right side
