Wow you are into some good mods and fabrication. I have no clue but I hope Rich or some of the other VG people can help out.

Changing the wiring would do it .. several guys have done it but end up going with a Doolz TT MAF -dual intake with a AFC-II controller. Only need it when your above 400 hp.. Tho I have seen one on a Stage III 370 injectors . The KEY to using a dual intake or a larger MAF is the AFC-II controller.. Your also able to run the larger 555, 750 , etc injectors but will need a rebuild on your engine to give it any kind of LIFE. The pistons fail on stock block above the 425 and above HP Z's

You would need a good dyno session w/ a piggy-back fuel computer or a reprogrammed ECU. My question, though, is why? The Z32 MAF is good for ~ 550WHP. If you are at that leve, then you are going to see better benefits from going to a dual intake setup, wither the JWT dual pop, a custom dual MAF setup with proper aFC settings to add the signals from teh 2 MAFs, or the Doolz setup w/ a reprogrammed ECU. What other mods do you have?

A JWT POP charger can be had for ~ $100 and will give 15-20HP. A good catback exhaust (LaBree, B&B, Greddy, HKS, etc.) will give 20-25HP for $600-1100. An upgraded ECU from JWT along with the included boost jets will give ~ 65HP for ~$550. Altogether, for $1500 or so, you can gain about 100HP. You will probably need an upgraded clutch soon after going to Stage 3 though ($400-550, plus installation (if you don't do it yourself)).

If you are still stock, I would definitely just get a replacement Z32 MAF though. You might contact Z1 (www.300zx.com) to see if they have a good used one for a decent price.
