quick question on what to use
ok the car is a 99 sentra with a ga16de engine
the few not to expensive and possible options i thought of are Safc and bigger injectors, FMU and stock injectors with low boost, or extra injector controller with a charge pipe mounted injector.
FMU cheapest but probably the worst
Safc and larger injectors is about the same price as eic and 1 injector but which is better i have no idea.
this is for 6-7 psi on stock motor and i believe stock injectors are really small and i will also be upgrading the fuel pump no matter what management i use.
if anyone has any better ideas then the ones posted for around the same price lmk
Thanks for any help in advance

Re: quick question on what to use
im not a fan of the extra injector setup. I dont see how the extra fuel can be evenly distrubuted across all 4 cylinders when its comming form the charge pipe...it just sounds like a problem waiting to happen.

Re: quick question on what to use
TBI is pretty much the same thing. It works fine but the problem is that its on or off. If you could have control over it then it would be ok. It still wouldn't be ideal cause you do get more fuel to some cylinders than others, but it would be better

Welcome to cars. If there's anything else you need disillusioning about, let me know. I'm chock full of bitter wisdom.

You're fucked for exactly the same reasons.

Re: quick question on what to use
you run it wide open and shut it off with it still full throttle, then look at the plugs. You will have to do it somewhere where you can run it fast and have room to pull of the road.
