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.
