How would I go about with putting a b18b automatic motor into my 5-speed 96 civic coupe??

 

You'll get this. Lots.

Why?

It's hardly a popular conversion, but i believe it has been done. If you desire to do the swap for personal reasons, etc, then sorry for intruding. If you desire to do the swap because you/your spouse/relative can't drive stick, then i'll stick in the usual "it's not that hard to learn"

Good luck anyways, finding decent swap info will be one of the hardest parts.

Edit - Do you still have a D series in your civic? becuase otherwise you will have to use a D series tranny. B+D= no go.
