I followed the instructions from Alta...In Aus we dont have the electronics component for all the pollution gear so it was a little bit more straight forward. (No MAF sensor)
All that was removed was the box and filter, and then the elbow and turbo inlet tube was clamped to the existing hosing. The hardest part was getting underneath the housing to tighten the bolts.
I might email the guys from Alta or jump on their thread on NAM...
