i have a 91 civic si and i need trans for it will a zc trans work on my d series motor guy told me i need use b series axles , i don't really know hole lot about honda's i just don't want to get screwed lil help pls.

 

You'll need 90-93 integra axles and a ZC halfshaft to use the ZC transmission, but I'm not sure if the halfshaft will bolt up to the D16a6 block. I know the wagons came with a halfshaft and shared the D16A6 with the Si, but not sure how similar the wagon and ZC halfshafts are. Maybe jlicrx will chime in here.
