The bumper can stay. Figure on at least a weekend but if you work efficiently it could be as little at 6 hours. Might need a machine shop if the studs on the exhaust maniold to turbo strip out too bad.
-Remove stock intake box & VAF. (if present)
-Drain coolant.
-Remove radiator & fan.
-Remove PS pump. Lines disconnect by Pass. strut tower.
-Unplug O2 sensor.
From under the car - (jack up front if necessary)
-Remove turbo support bracket to block.
-Disconnect turbo oil drain. It will probably crack, replace with new rubber line.
-Disconnect downpipe bolts(3) Be liberal with penetrating fluid and/or heat
Back up top-
-Disconnect both coolant lines to turbo
-Disconnect oil source at turbo then at block. Don't loose the copper washers at the block, they're easy to drop.
-Undo all the ex. manifold to head bolts.
-Watch the tab on the coolant bypass tube on the lower right exhaust stud. It will need pushed out of the way.
The turbo/manifold assembly should now slide out toward you off the studs and you can pull it out. The bolts / studs on the manifold will likely strip, use liberal lube/heat as needed.
Turbo gasket kit can be had at most autoparts stores. Reverse for re-assembly.
This was written off the top of my head but should be fairly accurate - post if you have any issues.
