Keep in mind that some MAF (and the DSM MAS aka Karmann-vortex MAF) outputs are frequency based, while others are an analog Vout of either 0-12v or (more commonly) 0-5v. This is why we can put freq-based GM (Hitachi) MAFs into DSM with a little fangling, or Ford (hotwire/analog) MAFs into Nissans with some fangling. AFAIK, the only Supras I've dealt with are Mk3's, Supra MAFs are hotwire/analog units and the DSMs are all freq-based... they are not compatible with each other, so you need to be careful before you swap anything onto your Mazda.

This isn't even addressing the problem of calibrating the MAF output to the ECU...


PS - SERious, Spec-V engines have rods the size of Honduh D15's, compounded by those heavy oversquare slugs on the end of them. If your stock MAF can read up to 8 psi, shouldn't be a problem... I'm going to be a dick and say you engine can't even handle that.
