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.

Thats ok that In your opinon it can't handle 8 psi. In the past, people thought that but, right now people on the "vboard" are doin that and up to 10 pounds so i know its possible on stock internals. but thanks for you concern plus ur right they are weak as ----. anyways i'm planing on building the engine this summer hopfully with my Group buy goes though ill have some new rods and pistons but right now we need 20 more people.....and the crowd that follows the spec are kinda lame with what they go though with.....alot of talk no show kinda ---- thats why i asked here for when i need some true help.
