I am not very familiar with turbocharging, but it's something I want to do in the future when I learn a little more about them. The only 2 kits I know of are the HRC and the Star Performance. I am hearing people talk about a new kit soon to come called the NER. I don't even know what that's short for. Can someone give me some detailed information on this kit? And perhaps tell me why it beats the HRC and Star in comparison?
