The KA24DE is a Nissan engine. THe point is, if Hyundai can do it with a heavy car and a 4cyl then we could do it with an old Nissan 4cyl and make it better and faster with a car that is comparable in weight. The turbo from a diesel is made by Holeset and was just an example of a useable inexpensive path for a homemade KA24DE turbo build.
