Today as I was looking at my fully stock engine bay, I thought hmmm I can relocate my battery to the trunk and make a short intake so that the air filter rests where my battery used to be. This way the intake is not close to the exhaust manifold and its less space.

What I need to know is:
How to relocate the battery to the trunk. (What cable to use, where to buy it, how to adapt it to the other cable)
How to relocate the MAF sensor and all those things that need vacuum from the intake. (Like that thing next to the exhaust manifold in front of the brake cylinder)

Will this affect power in a positive or a negative way? (CFM, vacuum, idle, etc)

Battery location and intake how-to's are on ths page http://www.240sxtech.com/ not to mention all over the internet.

That big nonsense in front of the BMC is the PAIRC system (emissions crap), you don't actually need it at all (s14's dont have it), but you can't just "remove" it either, w/o plugging a few things. Read up on it.

Near as I can tell, it's going to be a whole lot of work to not actually make anything run any better, and may make things run worse, esp if you don't get all the vac and pairc stuff dealt with correctly. If you're going to trunk the battery anyways that's one thing. But I wouldn't do it JUST to do tamper with the intake. Even if you are trunk'ing the batt anyways, I still wouldn't bother messing with the intake.

Of course it's your car and you can do as you please with it. Just sayin there's no real reason to do it. Unless your reason is "because I want to", in which case that's a perfectly good reason :bigthumb:

I did that exactly. except i cut a hole into the battery tray and ran the pipe through the hole. I didnt notice ANY significant gains. its a waste of time. keep it stock and put a good filter in your car.
