Need more fuel!!!!!
 

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?

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

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

i was told that s123 ones wouldnt fit?!? lol

i know a fiesta oil pressure switch comes on at 8psi which it slightly better ill have a look in the how to section then cheers guys

having the ecu remapped would be much better, if danny will do it you, then i'd av that done, otherwise, for a quick job do the 5th injector, i'd get an ajustable pressure swith, demon tweeks should have one, i'd get it on a dyno and see where it goes lean, then have the injector come in just before that.

many moons ago HKS has PFC F-con and GCC programmed for S12 silvia and aftermarket ECU. if you're lucky you might be able to find them.

I managed to get a HKS ignition module for my s12, but it was six years ago. Plus all the instructions were in Japanese :eek: and I had to get them translated :confused: .
Don`t think they are still available now though.

s13 injectors do fit, you just need to attach fuel hose to them. who said they didn't :confused:

As long as you have a late enough ECU with a 28pin EPROM chip its relatively easy to change most things :)

i've got some s13 injectors you can have if danny's gonna try and chip it!
would do us all a big favour if he found a cheaper mod for the fuel;)

well yes if you offering to donate i wont say no its all in the name of tuning!!
ill have a chat with sideways_danny and well go from there!!!
