hi all hope someone can help me on this one

i have a zetec turbo and am using side feed injectors i want to upgrade them to bigger ones
i have heard you can use the nissan 200sx ones but the main question is that a friend of mine gave me some side fed injectors that are from a subaru which are yellow and are 440cc high ohms so was just wondering if they will do the job

thanks all

 

depending on the mapper, your turbo and Fuel pressure they should see you to 300bhp ish, or close to that!

Obv they is a rough estimate your engine spec will ultimately determine exactly

 

the engine is as follows
ofab management with 195 chip
its only 1.8 zetec turbo
t3 hybrid turbo oil cooled from s1 rs
calibra turbo pistons
bigger cams
bigger throttle body
front mount intercooler
induction kit (piper cross)
magnex full system
ngk spark plugs
performance ht leads
decat
plus other bits and bobs
not sure what a 1.8 zetec can hadle regarding bhp etc but only want a reliable bhp 220 maybe alittle more dont want to go to stupid as i have 3 young kids but need that kick when driving on my own (if you know what i meen)
does anyone know any good mappers in the nottingham area

 

i ran 440cc injectors on my zvh and they didn't fuel enough at all for 14psi, not sure what 440cc ones would be like on a zetec turbo.
i went over to siemens deka 630cc ones now, no fuelling issues
although not sure they come in side feeds.

 

how much bhp are you getting at 14 psi on your zvh
i can adjust fueling on my fse power boost valve i think they will be ok as the ones i that was fitted to the car when i brought it are running ok but only have a flow rate of 150cc so 440cc is a big improvment
what do you thing all

 

Again depends on your fuel pressure, do you know what it was at? My mate is planning on using 440's on a gt30 and he should see 300 on that.

440's should be fine for what you are aiming for mate.

 

not sure i think 3-4psi of fuel pressure on the 150cc injectors thats what was showing on the gauge on the fse

 

3 - 4 psi?? U sure? or do you mean 3 - 4 bar??

Im using 650's and run 3.5 bar at atmouspheric pressure, then on boost it rises 1 psi of fuel pressure to 1 psi of boost pressure!

 

i run 3BAR on my Deka's, but ran 3.5BAR on the 440cc ones (390cc@3BAR, 440@3.5BAR so 390's realy, but fuel pressure raised them up)
i was informed that 440cc injectors would be ok for 300bhp, but seeing the duty cycle over 100% means that i was causing harm to injectors to get fuelling right.

 

yes sorry 3-4 bar of fuel pressure so i guess they should be ok to use as i dont want 300bhp
