I have also purchased one, but have yet to install it. After some searching around, it seems that one of the only places to fit the can is behind the drivers side headlight, by the battery (unless you've got a FMIC or no cruise control). Someone else rec'd that spot, and it seems to fit nicely. As far as plumbing, I've read a ton about how to do it and don't quite "get-it" yet, so it's sitting in my closet still
I don't have any pics, but I can describe how I did it pretty well. First think I did, was I got 20 feet of 1/2 inch rubber tubing at home depot, and got two T connectors for it. I just did that cause I didn't like the tubing that came with the can and I they didn't supply enough since I wanted to get rid of the metal tube on the intercooler.
Ok first thing is you have to find the two places on the engine that the air is coming out of. The first one is easy, it's the tube that is attached to the right side of the metal tube on your intercooler. Just pull it off, and attach a T connector there(you can shorten the tube a little if you want). The other air connection comes from the engine right between the compressor housing of the turbo and the engine. One tube goes back to the engine and one goes to the turbo inlet pipe.
The cleanest way to do the install is to take your indercooler off, remover the old tube connecting to the turbo inlet pipe and connect the new tube to it. YOu can just use a connector to connect the old hose to the new, but I like a clean job. When you do this, you must plug up the whole on the turbo inlet pipe since nothing is there anymore. I did that by taking a piece of the old hose, filling one side with glue and putting it back on the turbo inlet pipe. Now, the hose that you connectet to the spot near the turbo has to be routed to the T fitting that you put on the right side of the indercooler, and then routed to the catch can(those are where to air comes from).
Now, it would be easy to route the return line to the right side of the metal tube on the intercooler and the installation is done. I don't like that metal piece though, so I took off the metal tube, connected a the other T conncection to the two rubber tubes that were connecting to the left side of the metal tube, and routed a The return line to it.
I put my oil catch can between the battery and the front of the car and mounted it by welding it to a piece of metal, then screwing the metal to the car. The return line and the line that comes from the left side of the engine are tied together and right in from of the intercooler. Then they come to the T and go to the front of the car where the oil catch can is.
It sounds harder than it is. The hardest thing was mounting the can.
Filters out oil that would normally be routed back into the intake tract. Turbo cars are known to have alot of oil blow-by as compaired to NA cars so it helps keep oil out of your intake and more importantly intercooler, which i think would pay off in time.
