Well, it is no secret I like what Rob at Needswings sells. I like his CAI, the Catch-can to keep the junk out of the SC, and he is working on many other little things to produce more HP...his mani's for example...as well as some fueling mods...but, you, my friend...start out simple...if you like his CAI, then start there...I like the Code 3 pulley, but, nothing wrong with a crank pulley, but do tune the car if you go with the crank pulley. Take your time and read thru the threads...all the mods and see how others have modded theirs...if you don't understand, or the translation doesn't make sense to you...just ask any of us on here for help...we all are glad to help, but do understand, we are all kind of different in our approach to more horsepower...
