It was all pretty easy. I started on a Friday night, worked through Saturday and finished Saturday night. There isn't really anything hard about it, just that there is so much to do. I think the hardest part was either the installation of the blue box (tedious) or putting the manifold on. The bolts under the 3rd and 4th cylinder ports will only go on if you have little asian hands to move them into position and then tighten them.

I don't know about tools but look over the instructions that Greddy provides to see if you need anything more than basic hand tools. I had a full set of hand tools plus air tools in my garage, so I really didn't have a need for anything special.

The clearance may be pretty tight with the larger radiator. You will need to cut the radiator fan shroud to allow the wastegate room, but it may be more than what I cut off. You will also have to reroute the AC line that comes down between the two fans since the turbo directly interferes with it.
