instead of going after a kleeman charger why doesn't someone contact lkq and have them locate a slk32 motor with all accessories and just do the swap. it seems to me that it would be alot easier to that then to spend 8 to 12 grand on a bolt on that will never have the capability of the hand built amg motor. also i'm sure that it will also be easier to figure out how to go from the auto tranny to the 6 speed, then to try to figure out ecu programs. imho.
