if youve never had the turbo off before and the motor is still in the car its a bitch of a swap.
It takes me 5 hours to do it and i know every bolt and tool needed so expect a little more time for anyone not experienced. The whole manifold/o2 housing and turbo need to come off as one piece. Nissan put a special lock washer on the turbo bolts so the nuts would not spin off. These lock washers do not allow a wrench/socket to go around them and they are very inaccessable. so the manifold needs to come off. all the lines are the worst part of the swap.

removal
installation
burping the motor and checking for fuckups.
This time i said was for fully stock swaps with a/c since we all know all that bs on the shock tower for cold start and ac lines and other bs.
