Hoping someone on here can help me out with my situation....

Right now I have the aluminum Hitachi Maf Sensor that originally came with my 1995 nissan hardbody vg30e 4x4.

I recently sucked in alot of mud/water and blew the stock vg30e motor. The sensor is obviously covered in mud as well, and reguardless of it working properly I would like to replace it. Since I have an extra Maf laying around, I was just wondering if I could replace it with the Maf Sensor that I have from my 1995 240sx (ka24de). I have the pigtail harness and it is a three wire swap over. This maf sensor is a JECS and is plastic, in addition it has a much better flow design to it, which would be a benefit as well since the engine I just installed into it my truck is the slightly larger vg33e from a qx4/pathfinder/xterra

Basically... Can I use the pigtail from the 95 240sx maf and wire it into my harness and run the 240sx maf without having to retune the ecu or Run an apexi S-afc?

PS: Im running all stock hardbody sensors/harness/ecu. And i also realize i can clean my original maf sensor (which i have already done), but i am still curious if i can use the 95 240's maf.

any info is greatly appreciated.

Heres a picture of the two mafs...http://www.heavy-pork.com/truck/maf-sensors.jpg

To be on the safe side I would say no. That's definitely a strange looking MAF, never seen one like it before, not having the hot wire in the air flow. Seems like it would actually flow a bit better than the KA sensor really... but, either way since the VG isn't really making much power I wouldn't worry about the flow too much. You won't be near the limit of either.

Anyway, I'd use the VG MAF if at all possible because its highly likely that trying to use the KA MAF would require an ECU tune.
