Question MAF "Replacement" Adapter...

Because of the kind of intake im using on my car (its a MAF designed intake but I have the 2000 MAP 2.5) I'm looking to find a MAF replacement section so I dont have to use the restrictive stock MAF that I dont actually need since its not pluged into anything...

So I'm curious if anyone knows if any shops sell them, or if anyone could make one.

I found this picture online which gives you a better idea of what i'm talking about:



I couldnt find any info about that one since the website that used to host that pic is defunct now or something.

Anyway, the measurements of it are 4 3/4" long, and the pipe is 80mm OD. A regular MAF adapter is only 3" in diameter and significantly shorter, so it doesnt really work...

Update: I emailed the guy who had this picture on his website... Said he still has that adapter, so I'm buying it from him Pretty cool.

The JECS maf is a marked improvement over the metal maf. But..... it still can be maxed out. I am hitting 4.5 volts at 10 psi and since I will be back at 13-14 psi by Tuesday, and expect to get to possibly 16 psi soon, I know I need a little more range in the MAF.

So......

If you look at the JECS maf, the opening at both ends is 3". But the intake side suddenly restricts to 2.5". I plan to bore this section out on a milling machine.

The catch is that the area that is restricted, is also smaller on the exterior, meaning that if you were to bore this out to the same diameter as the rest of the tube, you would cut All the plastic and the MAF would be rendered useless.

So I will be filling in the sections with epoxy first, and the plastic ribs will hold the end section to the main section. Then I will be able to bore away!!!!!

Also, if you are going blow through, you need to fill the area around the MAF sensor insert with silicone to prevent pressure from reaching the electrical area of the MAF, since it will just eventually blow out.....

Are you plugging your intake tube into the stock airbox? If not I'd just put the filter on, snug it down and call it a day. If you are attaching to the stock air box, maybe you could just go to the junkyard, pull that MAF section, remove the sensor (maybe even turn it upside down to hide it a bit more). Probably a cheaper and easier to find solution.

Thats exactly what I already have It took a bit of work to remove the sensor, and I had to epoxy the hole closed, but it still has a rather nasty restriction.

Ill post pictures when I get the adapter. Its from a 300zx kit of some kind btw.

P.S. I know its not really worth any horsepower or anything, but I figure i'd try it out. I have a couple of other stock intake setups and a cone filter w/ maf to fidle with too, so ill have some fun next weekend trying stuff out

The question remains, why not just get a non-MAF intake right from the start?

Because...

I'm using a old 1.8/2.2 intake which is basically a CAI but its stock and wont get me in trouble if my hood gets poped during the current CA modified car crackdown craze.
