Is there any custom fabrication or welding required?
Yes. A section of the passenger side frame rail (approx. below the mass air meter), needs to be cut out, and a supplied plate with recessed area needs to be welded in place of the cut section. This is to adequately clear the passenger side turbo. The turbo will not fit without hitting the frame rail otherwise. This is not a big deal though. Since I did not have any air tools, I ended up cutting the section out with my trusty Dremel tool and a bunch of the carbide disks. You can have a shop weld the plate in, or have someone come out and weld it for you (as I did) for a nominal charge. For a picture of the cut out area and plate, go to the official INCON FAQ page. INCON has a a smaller kit that has a lower max HP rating (600 HP max), but does not require any cutting or welding of the frame rail due to smaller turbo housings. These turbos also spool quicker, getting full boost by 2200 RPM!
