Sorry guys, Im a noob, I'll admit it. I just bought a 1990 SOHC 240sx and Im gonna TRY my best to throw a SR in it. Do I HAVE to relocate the battery to the trunk or some where else or is there any way possible I can keep it in the engine bay. I'd really appreciate some help

You don't have to relocate the battery to the trunk, but you will probably have to use a smaller battery, if you are planning on running a front mount. You need the smaller battery to clear the piping that goes to the throttle body. However, this will also depend on what intercooler/piping you use.

If you have any kind of audio system in your car I would reccommend moving your battery to your trunk instead of getting a half size battery.

Its kind of an annoying process to do, relocatiing your battery. But like dub said it makes everything look so much cleaner. I need to do mine one of these days.

I have a distribution block in my engine bay that goes to the starter, ACC, and battery in the trunk. I ran a 0 gauge wire from the passenger side original battery location, up under the fender (tucked away really nicely), into the cabin. Then after in the car I ran it under the passenger seat where I put a 300amp inline fuse to prevent fires. After the fuse it goes under the carpet and wraps around the sides of the trunk. Let me see if I can get some pictures.

okay cool that is exactly how I was planning on doing it, other then the 300amp fuse, which I think im going to add now. I dont feel like trying to tuck the wire under my car.. Although its going to be a pain trying to hide the wire going into the back seat, and then into the trunk. I'll figure something out though.

+1 for nissan for having that handy little hole in the firewall eh? I find 240's have lots of nifty little things like that.

ya to me, dub's way seems like a pretty legit way of doing it. I may put the fuse closer to my battery though
