Im still having problems with my b16 in my 91 EX. I have the battery relocated in the trunk and running 1 gauge wire to the front. I am using an optima red top battery (about 6 months old) It is grounded in my to the frame in the trunk. Its in a taylor made aluminium battery box sometime i can start my car up on the first try no problem, but then after a day i can't start it up. i have to wait like two days for to start up again. it sounds like a dead battery because i only can hear the starter clicking and not turning the engine, but all other electrical works fine (stereo blasting, head lights on, honking horn). could it be a bad starter? i am running out of ideas. the problem started after i relocated the battery though.
