I think the hardest decision is deciding which way you want to go, after that its just making sure you research your choice fully. Unless you can afford to go trial and error, and possibly blow up a few engines in the process :P There are definately a good amount of reputable company options available for either super or turbocharged kits. As well as building your own turbo kit if you have the time and drive to do it right.
