I'm trying to improve performance in a S13 naturally aspirate. I'm thinking on a 300zx non turbo MAP sensor swap,is bigger than 240sx MAP so it is a good idea or not any help on this please. thank you

you'd see no real gains on a n/a motor, don't touch the maf, literally.

It won't help you, if anything, it'll hurt you. Larger MAF sensors lose a bit of accuracy. Upgrading your MAFS is for engine making too much power for the stock unit, usually through forced induction.

so you tell me if i swap my MAF from a 300zx non turbo could hurt my S13 KA24DE's performance, right?. What you think if i swap it from a S14 MAF,is a bit bigger than S13's MAF, just look at the following picture, it's a n/a S14, and those are stock unit MAFs.

you will not see any real gains, you are better off leaving it alone. Spend your money upgrading the suspension and saving for a turbo kit/swap

i dont think the na ka has the potential to make more power than the stock maf can handle(ok, nasport motors dont have a maf). you want to start your upgrades with simple bolts ons. quite a few hp locked up in that exhaust(including manifold). i/h/e with advanced timing and premium is a semi-hot setup.
