Should be lots of info, even a sticky at the top. Ive never checked it, but it should have good info. Its easy, lift the car, take off the bottom plastic thing, should be 4-6 screws that take about half to a full turn. pull that down, get under the car, about where your headlight and grill are, draw a invisible line down and slide under right there. Look up should be a good sized black pipe right infront of your eyes coming from the turbo, from there you should be able to locate your dv, its on the top side of the black piping.

put your car on ramps/jacks (front)
remove belly pan
get under passenger side, DV is near radiator/cooling fans
1time OEM clamps are a bitch, use an L needle, if u cant break them, dremel them off
reinstall new DV, noting orientation of old one before you remove!!!
drive

 

everyone suggests doing it from the bottom but i did it from the top. you just gotta find a friend with little hands lol. just look down in between the pulleys and the radiator, should be down about a foot and a little on the left. if you still can't find it, follow the blue vacuum hose coming out of the intake manifold. it goes right to the dv.

here's some DIY articles
