I have a 2006 V6 with a V2 s/c. The engine started to show signs of predetonation several months ago when it kept blowing plugs (another poster helped me out and suspected the ring lands were blowing). The engine has been showing weird signs before then (bought the car May of last year). I am on Long Island (NY) and planning on having Mustang Magic tune the car when it is ready. Since I have to change the engine I may add another v6 engine and swap over the entire s/c package complete with injectors or should I just dump everyhting and convert to a 4.6 - not sure about this one? Either way, can anyone recomend a mechanic near me that can install the engine and knows how to properly set up a s/c?
