Need more fuel!!!!!

[mr_turbo]

does a s13 uprated fuel pump fit striaght in? plus is there any upgrades on injectors or a straight swap upgrade from anouther car?

or is the only way to run a 5th injector on a pressure switch so only works at certain boost?

[s13eater]

se nissan used to run a 5th injector, crude but cheap, i had one, big tim has my old set up and i think cnhss1 has one for sale, the se one used a metro oil pressure switch, it came on at 5psi, much to soon imho, an ajustable one would be better, just find out where it leans out, then have it come on a couple of psi before.

walbro 255 will fit in the s12 cradle easily. I wrote a how to in the 'how to section'
theres also info in the how to section on fueling . Put some s13 ca18det injectors in with a piggyback ecu

[s13eater]

aftermarket ecu's can be expensive if your looking for cheap mods, but are the best, the afm's are very restrictive, especially on an 8 valve, where breathing is bad to start with, i think they are about 54mm.

i dunno how good this would be, just saw it on ebay.

same lph as a walbro, dunno how reliable they would be.

get some s13 injectors and i'll do an experimental chip
