RE: backup motor
if you do get the C6 i highly recomend geting the RB 2045 pipe to go with it. i've tryed the jp2 with my C6, it just wasnt as good a match as the 2045. the rb pipe just seems to squeeze every drop of power from the engine. also i went from 8 min with the jp2 to 9 min with the 2045 runtime.
