i plan to swap to a b18b auto , would it be a good idea to supercharge the auto b18b?? would the tranny able to handle the power??? thanks

Simply put, no.

Honda auto tranny's suck when it comes to adding power. they just cant seem to handle it. i know a kid who bought an auto accord and the thing was mint... he put an exhaust and CAI in within a month the tranny started to slip. this may be an extreme case, but you get the picture
