s15 injectors, it would appear..

edit... 480cc at 4bar

A set of these sold for £50 recently on here (as in sxoc)
Il offer you £50 for them.
Were they defiantly from a sr20det and not a sr20de?
As the de injectors are very similar in colour and only 270's

S body Sr (sidefeed) will not fit ca (topfeed). For cheap upgrade injectors look for pulsed or some skyline injectors, do your research but 444 (topfeed can be had cheap

S15 injectors work at 4 bar, not 3 bar like S14 injectors?
Are they actually different, or just use increased fuel pressure for greater flow?

[clive]

Yeap, so it seems after search as they actually only flow 440cc on base pressure...

[Actual_Ben_Taylor]

Hmm, could be 270cc injectors from an SR20DE, hard to tell from that pic.

[immy21]

I thought it was 3.5bar for 480
Yeah they are different to stock Sbody DET injectors, 370cc@3bar, S15 444@3bar although listed as 480

But ca18det injectors are 370cc@2.5bar?

[ross_striker]

on abit of reaserch yes these are s15 injectors (from a det)

Need to sell these and buy 444cc skyline ones for my stage 3

Anyone have a set?

Cheers guys!

I know where there's 6 injectors from an R34 GTT, not sure if they match what you want though?

[R3K1355]

Don't they run the RB25DET not the RB26DETT??

[immy21]

Some RB's are sidefeed some are top feed, going by ^^ 25 side 26 top?

Can't remember, anyway, here is some usefull info of most Nissan injectors, OP, my offer still stands.

Yeah, RB25DET Neo which has top feed injectors. I think they're high impedence, not sure of size. I'm sure google will know

But ca18det injectors are 370cc@2.5bar?

CA Fuel system pressure is not injector rated pressure.

If you need bigger injectors and not in a real hurry, i am currently looking for bigger ones too. I got 510cc from mitsu evo, came with cleaning report from rc engineering.

As soon as i set my mind on the ones i want i will sell these, the thing is i have very little time at the moment and it is already used to change many suspension parts (going from PU bushing to rose joints on every arm, even lower ones, changing coilover springs and brake pads). I guess it is a matter of a pair of weeks.

Bear in mind you will need a remap with a new set of injectors, and if you want off the shelf remap you will need 440cc injectors from another nissan engine (i quite never remember which one. Also i dont recommend chiping but hey... its cheap), not 510cc. Yet 510cc@3bar should be near 440cc@2.5, but i would not risk it, latency could be different. The 510cc are around 820µs .

FYI i max the 510cc with around 1bar T28 pressure, 3bar fuel pressure, e85 fuel. It gives around 300hp. They should be ok for 1.2bar pressure on regular pump gas.

If you are interested, send me a pm.

CA Fuel system pressure is not injector rated pressure.

So what are CA18DET fuel injectors cc? 370cc@3bar? Or 370cc@2.5bar?

[croustibat]

they are 370cc@3 bar, but the CA fueling system is @ 2.5bar, so they are a little less than that, around 330/340 i guess.
