Gonna build an intake - Page 2

I had a thought, why don't you just remove all of the piping other than the piece that is connected to the blue cover. Wouldn't that allow maximum air flow rather than just removing the end piece by the battery?

you could i suppose, it would be better for sure, but i plan to use the stock pipe to make a "RAM AIR" kinda thing.

you could be hard core and put a filter straight up (chevy 350 style) with a small circular cut out on your hood. You coul build a small scope or just let it hang out

I've seen a few econocars with that kinda setup....and looks wise it only belongs on a muscle car....but for pure modding purposes it would work well, but don't you have to worry about the rain?

I'm not going to cut a hole in my hood

sentrastud · Jun 3rd, 2002, 10:20 PM

neither am i. That look is only for muscle cars. I said KINDA ram air. In other words the pipe is right behind the cooling fan with a big scoop thing gathering more air.

Time for an update: It took my airfilter housing off the car today. I was going to take off all unneeded metal, problem is I have nothing to cut it with. I tried a pair of sheetmetal cutters but they are not strong enough. I was thinking a hacksaw might work but it is not terribly precise. Anyone have any ideas???

What kinda air filter housing do you have and what did you plan on removing? I have a 90b12 and removed everything but the cover, I took off the intake pipe and resonator screwed onto the inside of the air filter housing cover. I didn't see much else you could take off. One of the downsides of modding this design in my opinion is that the breather filter resides in the filter cover. If there were an aftermarket breather filter that was designed for the b12 I would just try and find a k&n filter big enough to cover the whole air filter housing base and just leave the cover off, I think this is similar to what sentrastud is trying but he wants to find an air filter housing assembly from an 87-88 I believe.

My car is like a 87-88. A round filter sits in the housing but there is only one small inlet. I want to take all the metal out from around the filter. It's basically what Sentrastud wants to do.

Bust out your Dremel man.

At Canadian tire they sell mini-high flow filters called breathers. I think American racing makes them? Connect these up to any of the inlets that are inside the airbox. it might take some creatvie work but, when i get the car next week ill probably do this mod and seehow it works out.

I found this picture on B15Sentra forums i think, it shows someone elses homemade intake.

What kind of bit did you use for the Dremel???

sentrastud · Jun 20th, 2002, 09:18 PM

I havent done it yet. The Dremel has a small booklet with it thats called "175+ Uses for your Dremel" or something like that. I think somehwere in there they list all the bits and their uses. Look for the one that they used to cut drainpipe, it think that should do the trick.

Before you try it on the airbox though, practice a bit on some other piece of metal.

So is that your home made WAI? How much better is it than just your previous kn filter and stock air box?

sentrastud · Jun 20th, 2002, 09:42 PM

its not mine, I found it B15sentra forums sometime back. I dont know whose it is. Ive kept on my computer and been using it to see whats under the airbox and stuff.

Im not trying to do that thoguh. Remember on old Muscle cars and stuff how they had their airfilter sticking up with the filter exposed and a lid on top of it? Im trying to do something like that.

dschrier · Jun 20th, 2002, 09:53 PM

Oh I thought that was yours. yeah I think that would be pretty good to do too, maybe even as good as a WAI. I found a kn filter almost the same diameter as the stock, but it's 3" high and closed at the top. I was thinking of maybe using that and drilling holes in the top of it for screw posts, then you wouldn't even need the cover cause the filter would be tall enough to be held down by the wing nuts at the top of the filter. It would probably be a good idea though to try and put seals around the holes by the screw posts so no air gets down through them carrying dirt and dust. That was what I was thinking about.
