450cc injectors...safc and what maf?

[uncle_louie83]

well....i dont know the maf ordeal so i need to ask...

i have an safc...its already wired up....running and everything...im doing a top mount fuel rail swap with 450cc DSM injectors in the next week or two. I know the 450's are good to 300hp...ive already done the math...well the stock maf runs out at 250hp....SOOOOOOO....do i need to switch to a z32 or q45 maf with the safc or can i keep the stock maf with the safc...cause i was told that the safc bypass'es the maf....so let me know if i can keep the stocker or if i need to change.

You have to use resistors on the injectors don't you?

[Structure240sx]

you need the z32 maf. the same maf is used on z32 NA, TT and j30's

the safc works on our cars by changing the maf voltage

you will still need to replace the stock maf if you want to push more than what it is capable of. you can see it on your safc if you are maxing it out. i maxed mine out so i upgraged to q45 maf. z32 maf will be more than good enough for what you need.
