I'm putting together a turbo on my b16 and am wonderng what injectors to use with a v-afc hack @8psi? I've seen a lot of people use 440's, but I'm wondering if 370's or 310's might be better. If I have 240cc injectors stock than putting in 440's would almost double my fuel, could it still pass emissons leaned out all the way at idle?

 

Once you put a turbo on it then you will need more fuel. As for using 440/450s with the hack you need to be able to lower the safc settings enough to where the map voltage is less than 3.1 volts. If you use a smaller injector then you wouldn't need to trim as much which would then trip the cel. Read this thread

to understand exactly what it is you are doing when you use the hack.

 

370's will be good up 15psi just lean it out when time to smog and you should i pass every time same setup.good luck.

 

actually you cant use the hack when running 15 psi unless you get a gm 3-bar. Get yourself some rc 440's there more expensive than dsm but you wont have to mess with resistor boxs and stuff.

 

Thanks for the info
