I think he might of "clocked the turbo" i.e with his set up been external wastegated he dosnt need to use an actuator, there for the cold side of turbo can be spun anywhere you want it.. in most case's people do it to shorten the lenth of the intercooler pipe route giveing much quicker spooling time also depending how your turbo is set up people also clock a turbo because the oil return might be on an angle and needs to be faceing down so the oil can drain off the turbo
