Large Mass air flow housing?

Cgross609 · September 26th, 2010, 11:06 PM

Hi does anyone know where i can pick up a larger bolt on MAF housing for my 93 2.3? Currently mine is a 55mm i believe. I want to ramp up to perhaps a 71 or 73mm.

As well i'd like to note that when i completely eliminated my 55mm MAF housing, And just fitted a 3" Rubber ABS adapter, it felt powerful, and i could burn out of stop signs. lol. My current setup is a PVC Pipe CAI. It has a 2-1/2" to 3" Reducer, 45degree elbow and a length of 3" PVC. I know its not a true CAI, so please dont jump down my throat about it. I'm planning on making it a true CAI, but in due time. I just want to know if there is anyway i could maybe just drill a hole in the PVC and fasten the MAF on in some fashion. Would it work by any chance? I tried before but was unsuccesful, mostly because i think the MAF wasnt directly in line with the air flow. Somehow. I dont really understand it. Any suggestions would be greatly, greatly appreciated.

No one? Bump?

If you plan on just bolting on a larger MAF, it won't work very well at all. Your stock MAF is not a flow restriction on your car at this point anyway, so adding a larger MAF will only make you car run worse. If you have $250.00 burning a hole in your pocket and you are hell bent on changing things around, you can buy a Quarter Horse and J-3 chip module and teach yourself how to tune your engine, so you can put a larger MAF on your engine and at least it will run. That should at least keep you busy for a while.

The car was running better without any maf on there at all? i'm a bit shocked since you've taken a large part of the engine computer's fuel and ignition decision making out of commission.

regarding the cold air intake comment - for what it's worth, if you still are using the stock air filter box and you block off the hot air tube you do have a cold air intake, since it will be getting air only from ahead of the radiator where things are indeed the4 coolest

as for experimenting with a larger maf,besides the correct way which OHC suggested, you can always trial and error a 71mm mac performance maf housing and try out their various size removable maf sensor sampling tubes to make the maf read correctly. i'm sure mac has never done the research for a 2.3 so you'll be trying things out from scratch.

I had a 3 inch rubber coupler to the ractive cone filter i'm running, and i couldn't figure out a way to get the MAF to read right, because below 2000 rpm, it would spit and sputtter, idle at 500 rpm for a moment, and then die. So I just unhooked the MAf, said to hell with it, and drove it to school. lol. I'm sure it was not good for it, but the pickup was unreal. I could not believe it was a 4banger. I could stop at a sign, gun it, and the wheels would spin. It had more go than my dads ram 2500 with a cummins turbo diesel. It was incredible. but maybe that had something to do with my engine already having the air/fuel learned, and then it just reverted back to the map it used? I have no idea. But it was definitely running rich, i could smell it. thanks for the replies guys. lol. Didnt think i would get any

k... So now that i've messed with the intake... I added a 2inch peice of pvc, with the MAF mounted to it. It is weird. When I floor it, it hesitates, and will stall, unless i back off on the gas. Any ideas of why this is? Other than the fact that my PVC Fab job was less than mediocre. But more than nothing i guess. Lol. But i'm sitting here looking at a caliper, and 55mm is quite a bit more than 2 inches. Ah. Time to switch everything back around...

make sure you disconnect the battery for a couple minutes to reset the ecu between maf changes, and then let the car idle for a couple minutes once all is hooked back up again so the ecu can relearn its new parameters.

Shit. Forgot about that. Thanks Zonker. You da man. lol oh Hey. Does anyone know what the box on the passenger side of the engine bay is? Mine has a Z or an N on it. Its just a big black box, prolly about 7"x5 or so inches, and it has a large connector on the back with wires running fromit. Is this the engine management system? or something along those lines? lol
