I've got a AE86 with a CA18DET swap, i've moved the battery into the boot. When I've run the new battery cable i've put a 80 amp fuse near the battery. I'm using an AGU style holder and they only go to 80 amps. The biggest draw on the battery is the starter motor. Is an 80 amp fuse enough (only running a little battery to save weight)? I've blown a few fuses but my starter motor is iffy, it turns slow, sometimes get's stuck and I need to give it a hit to free it up. When it gets stuck it'll do a fuse as it's drawing too much power. I want to know what Nissan use.
