s13 Front mount Intercooler install advice
Hey I am about to tacke the job of installing the front mount intercooler and was wondering if there was anyway around doing a battery relocation? I drive a 1991 180sx and it cam with a small japanese battery, so there is room for me to trim the battery tray but will there be enough room? Should the pipping go on the outside of the frame or the inside?

You can use a smaller battery, and avoid relocating it to the trunk. However, relocating it is VERY easy, you can do it in less then a couple hours once you have the few things you need.

reloacting it is not hard at all. but if you dont want to spend money on it just use your small battery and tricm out the battery tray. its not that hard to install taken the bumper support off make be harder than installing he fmic. GL on it tho.

ok I have one last question, when installing the intercooler I noticed that off the side mount intercooler there was a hose that ran to the intake. is that hose needed with the front mount intercooler? If not what should be done with it?

that is the like for the stock recirc hose. if you dont plan on recirculating your bov just plug it up. i used one of theese little rubber plugs i picked up from a hardware store with a hoseclamp around it.

Cool thanks for the advice, is there any down fall to not recirculating to the B.O.V? Also, I ran in to one last problem, I am not entirely sure what to do with the two small hoses. The first one being the one that plugs into the piping that runs out of the throtle and across the fan shrouding. And the second being the one that plugs into the factory side mount intercooler. There does not seem to be a place for these two small hoses either on my front mount. Anyway, I appreciate all the help and I have been all over the internet looking for instructions as I don't have any. I have found alot of good stuff out there but it lacks specifics. Just want to be sure I do things right the first time. thanks

my battery relocation cost me less than 50 bucks. go to tractor supply and get welding leads, cut to length. low gauge and highly insulated, put my behind the passenger seat.

Ah i think I get it, you are saying to take the device that resembles a small megaphone off my blow off valve and replace it with a fitting that will tie back in to the stock recirc pipe. Is that right or am I way off base? If I do choose to recirc how do you adive running that pipe back into the blow off valve? I only ask because it seems the position of the pipe and the blow off valve would make it awkward to connect...on my set up at least. And just to clarify eventhough my set up has always been atmospheric blow off, the car stands to run differntly because that one pipe will be plugged? Anyway, I am sure walking me through all of this is getting frustrating but I do appreciate all your help.

yeah i was a little unclear on that. im not familiar with your bov but on my hks the fins inside the opening are removed and adapter is put in place. so instead of fins you have a port to stick a 1" hose onto. just search for a fitting.

Also, with an atmospheric BOV, the car doesn't stand to run differently because that "one pipe will be plugged". What happens is everytime your BOV opens, it lets out air that has been metered by the MAFS, this causes your ECU to send to much fuel, and causes a momentary situation for your engine to run rich, which can cause you to stall. The ways to fix this are re-locating the MAFS to behind the BOV and closer to the TB. Or a S-AFC or EMS. Recirculating it is the cheapest and easiest obviously.

You are right, I do have a Blitz blow off valve, I am impressed that you knew that from my lame discription. Now, where might i find one of these flanges, and if possible can i see a pic.... that way i know what I am buying. If you can't find one that is cool. Thanks a million for all the advice.

That thread has all you need for your Blitz BOV recirc... pics included, just click on the links at the bottom of each post/step. I forgot to mention before, if you have the stock rubber SR intake tube, there is a fitting you can use to connect for a recirc line on it right behind the MAFS. There's a pic of it in the writeup above.

So I went ahead and relocated my battery to the trunk. However, it is not a dry cell battery. So does it emmit any type of gas? I just bought one of those marine boxes, does this need to be vented and if so how?

Those Braile batteries are total junk. This is pretty common knowledge on the forums I frequent. They last less then a year even with good 16v trickle charge. |

To the OP: Yes, it's a good idea to vent the box somehow. IMHO the best thing to do for a battery relocation is to use a sealed battery (like an optima). That way you don't need a box. For my relocation I bought an optima redtop battery, 0 gauge cable, 4 gauge cable (for grounds) and a piece of sheet metal. I made the sheet metal into a tray, and carefully drilled 4 holes and attached it into the trunk with 4 bolts, and then used the stock battery tie down to hold the battery in the tray. Total it only cost me about $250, and my battery is SOLID in my trunk; not even a hint of movement, and it's super easy to change and/or disconnect.

who the hell do you figure? if i had my batter in my trunk, it would have the same exposure to me. the only reason its where it is, is because i didnt buy enough lead. k? just as illegal as it being in the "trunk". in this case my stripped out soon to be caged hatch. good day.

Oh, and another quick question, I have been looking at the DIY battery relocation thread and I was wondering if I have to run to wire to the altenator, starter, or acc line. I only ask because my wires look nothing like his. Is it fair to say that i only need to take what was attached to the old battery and run that into a circut breaker? Or is there some crazy things that I don't know about?
