Just like it's been said turbo is only held down by 3 17mm bolts. Two on the drivers side of the pedestal and one on the passenger side. The forward bolt on the drivers side is a royal PITA to locate and get to but all the bolts can be reached with a 3/8" drive extension. You'll need one that can clear the top of the turbo. I used a breaker bar to get them loose cuz mine were on there tight!
Remove any electrical plugs connecting to the turbo and the coolant feed and return hoses, and then the two oil drain line nuts first. The oil drain is attached at the bottom of the turbo, it passes under the pedestal and connects to the back of the block right in front of the transmission adapter plate. It's held on by 2 12mm nuts, the posts for the nuts can be removed with an 8mm socket it you want to make removing the turbo a tiny bit easier.
The oil drain line has a gasket at the connection and tends to stick pretty good so I like to free it before I try to remove the turbo.
I don't drain the coolant system when I remove the turbo but you'll want a rag or two to collect the coolant that comes out of the turbo coolant lines and it helps to free them up enough to elevate them slightly so the let out less fluid.
You don't need to remove the y-bridge, but you'll want to free up your wiring harness to move it out of the way to allow the turbo to be removed. The turbo weighs about 45-50lbs so be prepared to use some muscle to pull it out and steady it when removing cuz it can be cumbersome trying to do so hunched over the engine
It's not a terribly difficult task, you can do it!
