i met this guy at the track last night and he told to go to my local Ford dealer and get a Cobra MAF to replace the stock nissan one and it's good for at least 15 hp.
Is this true?? Or was he Blowin' smoke up my ***?
He said it was like 70 bucks too.

I know a guy with a Turbo Altima who's using a Cobra MAF. He said the Cobra MAF was configured for more airflow. I'm not sure how it's going to affect your max without any other mods such as ECU, etc..

Yes, it has increased air flow. JWT said they could get the MAF and the plug adaptor. They recommend upgrading the injectors and the ecu so to ensure the most benifitial gains with air/fuel mixtures. It's not a "kit," but should all be done at the same time to compliment each other and to achieve optimum performance gains.

Dirksmoothe

ok, so, with the Cobra MAF, if you get one and you don't upgrade the ECU and the injectors, you aren't going to get any perfomance boost?

run a little lean(MORE air than fuel in the mixture) if the amount of air coming in isn't sufficiently mixed with enough fuel....reprogramming the ECU and using bigger injectors will allow you to "match"(so to say) the BIGGER amount of air now coming in with sufficient amounts of fuel so the A/F ratio remains at stoich!(I think thats how it goes... )but Jeff couldn't an AFR or AFC do the trick to "fool" the stock ECU??

Mr. Rose

I own a COBRA, and I can tell you that the COBRA MAF is programed for 24lb/hr injectors. If you have a different injector size you'll need to get a WIDE BAND 02 Air/Fuel custom tune, or an ECU burn. Either way you go your going to be spending some CASH for the TUNE, about $450 and $75-$80 for the MAF.. If you don't have the MAF recalibrated, then you run the chance of leaning out Air/fule mixtures to the point of no return; I.E, burning a hole in a piston. THE COBRA MAF I have seen in special application for the SR20DET and 240SX KAs4 and KA24DET motors. NIssan was really "smart" in using a bottle neck MAF for these cars. Just remember to have the COBRA MAF recalibrated for your application.

Lets see if we can get a group deal going

Hmm interesting idea. I wonder if this is the way to go or not. Is the Cobra maf bigger in dia or just calibrated for larger injectors? I would think, getting a bigger throttle body would do more to get more air in. Both would be ideal I guess.

Mr. Rose

Both are 80MM (96-99/01 COBRAs), one is plastic, and the other is aluminum. That's a 3.1" MAF Jeff. Now they may be talking about the 302cid COBRA MAF. I beleive it is a 75mm unit.

Mr. Rose

...will retune any MAF to specific calibrations, and even sells Performance MAFs.However in order to have it totally match your car, you'll need a WIDE BAND 02 tuning.
The only FORD number I could find for a MAF is a performance 70mm for an 89-93 stang., but it is specifically tuned for 30lb injectors.part # M-12579-A70 which retiald for $219.95.

Considering it is a COBRA specific part thes guys will know what's what, and where to buy for cheap.

I've heard that the '90-94 DSM turbo guys do this....
they swap the Mafs from the later model(95+) Eclipses onto theirs and use the Super AFC to recalibrate("re"-richen the mix) to stoich or even custom gains by leaving it a litte lean in the low-end, couldn't we do the same...I know its hard to just say "yes" without hard evidence, but thereoretically it sounds good? and won't the AFC enable you to "tune" for bigger injectors without sending in the ECU, hell it'll take some hours on the dyno, but if you're that serious about this project couldn't this be an option??

Mr. Rose

a possibility.

Maximamike

Its part of the JWT 450 kit for the Z31 turbo. JWT has a program for it. ~$100 for a retune on their ECU's.

Do you have a number for that kit? I couldn't find the kit on my price sheet. I may have an old sheet.

What is a MAF?

Maximamike

MAF = Mass Aiflow Sensor. Its the thing on your intake tube with all the wires going into it.

Some info on the JWT 450 kit(from Z31.com of course)-->
================================================== ======
JWT 450 package: Uses an 88-89 (turbo or non) comptuer than JWT modifies to run 420cc/min injectors with a 1993 Ford Cobra air flow meter(cheaper, more reliable, and less pressure drop than stock unit). This also gets you the tweaked JWT fuel and ignition timing maps, which are very nice. At a cost of $600 (plus $250-600 for the injectors and around $200 for the Ford air flow meter) it is the cheapest way to get lots of extra power capacity in your fuel system. To get the most out of this system you will need a bigger fuel pump, and the z32 turbo unit is the reccomended way to go.

================================================== =======
The JWT 'sport 450' package(Is that the right name?) gives you 450ish horsepower when used with appropriate parts. Some ofthe more expensive parts they use can be had elsewhere at a HUGE savings.

The 1993 Mustang Cobra air flow meter can be had from places like carparts.com(That link gets you free shipping by the way)for around $125 or so. JWT charges $250. The wiring harness for the air flow meter is Ford part # F43Z-14A411-A and costs around $15(JWT includes harness with the AFM).

The injectors are bosch 280150036 injectors, which is the same thing as Standard Ignition fj118 and Borg-Warner 57512. Any auto zone type store will have them if you tell them you want 6 injectors for a 1975 mercedes 450sel with the 4.5 liter engine. Expect to pay around $50 each for them. JWT charges $100 each. Beware! JWT says to simply shave the injector connectors down so that
the Nissan plugs will fit on them. If you shave too much they will not stay on securely, and if one comes off under full boost you can damage your engine. JWT requires that the Nissan injector repair campaign work be reversed(ie. wiring reverted back to original) before installing the JWT computer.

did you actually read all that.......
