I had a d15 obd 0 distributor on my d16z6 block. To get it on there correctly, we had to cut off the end of where the bolts mounted in on 2 sides, and we flipped it a whole 180 degeree to get it to work. It ran good, but was kind of off on timing. I recently bent a valve, so I had to rip apart the head, and its all disassembled, other wise I would just show you pictures.
