OK im getting a LS swap from a friend for 650 including motor mounts for my crx only thing it doesnt have is a tranny...
so i was wondering whether i should get a LS tranny or B16 tranny and does it fit up or what do i need to do to get the b16 tranny to fit if thats the better option???

 

either transmission will bolt right up , if your going for allmotor setup the b16 tranny will help you more than the ls , but the ls isnt that bad . It depends on what your going to do with the car , if your going to make a track ***** then go with b16 , daily driven and expressway driving the ls is what u want . if you want to boost it well there are mixed opinions but alot of people perfer the ls
