To begin with the turbo doesn't come with a manifold which you have to get custom made. The B13 sentra does not have enough space for a side mount IC which it means paying for custom piping or even having to get a FMIC. You need to get a custom downpipe for that setup because the DSM turbos have a different flange than our T25's. You need to make a custom intake pipe. All your oil/water lines will have to be ordered made for that turbo and when you tap your block (If you are going SR20DE) pray to the car lords that they T25 DSM oil line will line up the one tapped on your block. If you want me I can keep on going......
