My cobra is TOTALLY STOCK no even an air filter. Is my daily driver, im looking to change a lil, without unlimited money to burn I was looking at a single turbo kit Vs. a twin screw blower ... anyone with good suggestions? I know that the differences have been beat to death but ... for a daily driver to take to the track here and there does the overall drop in gas milage and lowend beating of the engine well worth the price of admission of the twin screw or will a turbo setup just not be the way out im thinking it is? Any help would be great, thanks. To help out, im only looking to spend under $5k
