94-95 70 Mm Mass Air Swap For A Fox

BKM48198 · Sep 5, 2014

I am interested in getting a mass air meter from a 94-95 Mustang to replace my OE 55mm meter, I have been told that instead of using an adapter you can just cut off the mounting flange and it will slip on, I am wondering if someone else has done this if they could tell me the best way to cut the flange off.......hacksaw, die-grinder with cut off wheel, or some other way. If you have pictures that would be helpful also. Any problems you have ran into that I might avoid? I have a 96 Explorer gt40 motor with Mustang cam that was just put together and I am trying to get the most power from it I can WITHOUT different heads, cam, turbo, supercharger, nitrous, or anything else. Just want to know about the mass air swap. Thanks!!

Best way would be a band saw but either of the above methods will work.

I talked with a couple guys on a Facebook Mustang page that have done this swap and got a video of it, I'll try the cut off wheel and then round it on my grinder. They actually answered the question without telling me to swap out everything else on the car. I don't know why when I asked about this on the other thread people kept telling me to swap out heads, get a blower and even said to change to a 5 speed when I asked about mass air, TB, and injectors. I used to be able to ask a question and get answers from knowledgeable people but now it seems like nobody wants to read what people are asking for help with, I asked for a pic WITHOUT an adapter an a mod posted a pic of the adapter. Stykthyn you have been one of the most helpful on here and I appreciate that, unfortunately you are in the minority, on here it seems like for everyone trying to help there are 2 or 3 that don't even read what I have asked about..........including the mod that got upset and ended the post and said my question had been answered, when he really didn't know what the question was.

Sorry that you have had an unfavorable response here. Honestly I haven't followed this thread that closely, but I will say that the crowd here is for the most part one of the best shooting ones in the bunch. Lots of knowledgeable guys on this board which is why I stick around. Some get their feathers ruffled now and again, but most mean well. The 94-5 maf you are looking at is perfect for your set up and whether you go with an adapter or cut it to work will not make a difference. Hope you stick around.

Because of you and others like you I will stick around, I'm going to try to cut/grind it down rather than buying the adapter that would just add another lip which could disturb the air flow. The adapter is 1/2 the price of the mass air so if I screw up cutting/grinding it won't cost much more to get another and the U-Pull yard has 5 or 6 there now. I am really shocked at how good my gt40 build runs, when getting on the freeway it spins the tires hitting 2nd and 3rd if I have it floored, running about 2800 rpm at 80mph in OD, and I'm getting over 20mpg, could probably get 24 if I kept my foot out of it........but that is NOT going to happen, it feels too good driving it as a Mustang was made to be driven.

Thread moved to the technical section.

This is where tech questions go when you don't want the idle chatter associated with the Talk section.

This forum tries to keep things pretty straight up in the tech sections. PM me directly if you find that this is not the case.

The one instance I recall of using the 94-95 70MM MAF without an adapter was where the guy chucked the whole thing up in a lathe and machined down the flange. When it was finished, in place of the flange was a short tubular section to clamp the duct onto.

It turned out quite nice, but the only drawback was that there wasn't much room to clamp the duct onto the MAF, maybe about ~1/2".

I talked to a guy on Facebook that did his in a lathe, since I don't have access to one I'm going to try cutting and grinding one down and see how that goes, at most it will cost me $24 and some time.

I got the MAF today and got it cut and ground down, fits pretty good, my only question now is about the check engine light, it came on after starting the car so I am thinking the computer just needs to re-learn itself with the larger MAF so I unhooked the battery and am letting it sit for 30 mins. and then I'll try it again and see if the light comes back on, oil pressure and coolant were fine so I let it run just long enough to heat up and the thermostat to open. Is that all that should be done or does the MAF need to be grounded to the body?

I wouldn't worry about the cel at the moment. How did the car idle/run?

Idle was about 800 and ran just as good as before, only difference was the light.

If the light comes back after you reset the battery dump the codes and part them back up.

That's what I planned on doing if it comes back on, I have the meter out so it's ready to be plugged in if needed.

Pull them just for giggles. Computer will store codes without tripping the cel.

It won't hurt anything to pull them so I will do that, might not be till tomorrow since I have a few college football games I want to watch tonight!

Pulled codes 2x, first time I got 82 (Thermactor) and 66 (MAF low voltage) 2nd time only got the 82 code then system pass.
All smog equiptment removed from car except smog pump is still on.

BKM48198 · Sep 6, 2014

I cleared the codes and tried it again getting both codes, started it and had some surging for about 15-20 seconds and then went to a nice idle, surged between 500 & 1000rpm going to let it sit overnight and look at it tomorrow

Is your smog equipment still in place? What is your maf set up? Please don't tell me you attached a cone filter directly to the maf. Finally since it is a used piece did you spray the honey comb abd maf elements with cleaner after trimming them down?

No smog left except for the pump, I have stock air box with K&N filter, silencer has been removed, other than that it was all stock up to the 65mm TB. I sprayed it all out making sure everything was clean......I kept getting the MAF low voltage code so I put the stock back on and it went away, so since both are basically the same I swapped the electronics from one to the other and then put the 70mm back on and the CEL went off. It ran great spinning the tires harder when it hit 2nd gear and felt much better. Idle was perfect with no surging at all. I will see about taking the electrical part back and switching it out to make sure I have a spare in case this one ever goes bad.

I would put some di-electric grease on the connections to clean then up. May be all that's needed.
