So I want to ditch the SC and go with a Hahn's stage 3 kit. Is the Stage 3 kit enough or would I be missing essential parts? My cobalt is my dd and I would just like to be in the mid 3s for hp and about 300 for trq. I wouldn't be running my car hard every day, just something that i'd like to have for the every once in a while race down the interstate or at drag strips or stop light races. Any and all help is greatly appreciated. I want to keep the price below 3k if possible since I am having 3dMotorsports install it for me. If there is a reliable and more affordable route please let me know. I am trying to find a price to save for to have it done by summer. As of right now, my slowbalt is stock.
