will 310's be enough?
 

i am going to squirt my miata soon. i have 310cc injectors now, do you think they will be big enough for a 13g at 10 psi untill i buy some 440s or 550s?

with your FMU, yes.

damn, thats what i thought, but i wasn't sure. looks like i need to find some rx7 injectors then

i ran 7psi on my 15g fairly safe so i'd say it will be real close, just run lower boost if you can and you'll be fine. i wouldn't run a megasquirt and an fmu together, tuning will suck
