Looks like a nice clean car.
It appears that the heat shield is missing over the turbo. It's a little metal piece that has a burning hand on it. These don't fit over aftermarket down pipes, so my guess is that at some point this car had an after market DP on it, possibly it still does. If you can snap a picture of the motor on the passenger side next to the intercooler we could tell you.
And yes, some intakes go into the fender, but it also could have had a front mount intercooler on it at some point. Look for cuts in the front bumper cover.
Anyway, car looks pretty nice, and if it runs good without any smoke or weird noises than I would say you've done very well.
