Because when you turbo the KA, you most likely reprogram the fuel map in the car's computer...and this will make you use more gas.....thus throwing off your emissions.

Also...in Calif. , they do visual inspections as part of the emissions inspections.....so....thats the main reason you will fail.  To my knowledge, the KA-T isnt even legal in CA, because you have to have a turbo thats CARB approved...and I dont know if there are any that are (that people would consider using in their cars).
