Can I swap a D15B7 for B18A1

Hi, I to start with am a noob to the swapping business. lol. I need your guy's help. I have a 93 civic dx with the d15b7 in it. weak.... I also have a 90 integra with a b18a1, stronger.... Both cars run fine. Would it be possible to swap the b18 into the civic. Would I have to swap out the trannies as well? I obviously have all the parts for the b18 therefore thats not a problem. So, any advice would greatly appreciated. Thanks for any help thats provided, Nick
