S15 Injectors

[benl1981]

So many rumours..

It seems the oz spec ones are 480cc as well as JDM.

As long as you get the maroon coloured ones are they sure to be 480cc?

Thanks

Aus. spec SR20det and auto's are 370cc from my info.

Thanks Grigor - but some of what Ive read and what others are selling is aus spec maroon coloured injectors that are 480cc.

Is this BS?

I thought jap spec was 480cc inj.

jap spec is everything better.

Ive has a look on silviansw and it seems the oz spec manual ones are 480cc yet auto is 370cc...

[paulr33]

well the aus spec turbo is different

so that could explain and provide some weight to the aus spec having smaller injectors

Yea thats really interesting, i have one friend with a aus spec r s15 and his are the purple colour ones, another friend that has a s15 aus spec r 99 model, it has maroon ones... confuses the shit outa me

but yes all jdm appart from auto came out with maroon (so i've seen so far)

[n0nac]

they are 480cc

there is alot of debate on nissansilvia about them...

but actually flow rated at 440 or something cant member exact figures...

side feed with purple tops out of R33 skyline and s15 AUTO are 370cc,

with maroon tops out of S15 MANUAL 448cc and the JDM are 480cc from what I've heard

as i'm going to put these injectors in my R33 (maroon tops) before I do I will get them flow tested and then will confirm there flow at a given fuel pressure. I've read here and there and everywhere and everybody has a different opinion, so I guess we'll find out once and for all.

Tuners out there should know if they're tuning R33's with this upgrade as they're a pretty popular upgrade.

Cheers matt

The problem with the s15 injectors, is they're old injectors.

I would get them ultrasonically cleaned, get the pintle caps changed, change all the orings, etc etc.

Sometimes, they'll flow well, othertimes, they won't.

they're not that cheap at the end of the day after you do all this.

The deutchwerks highflowed injectors seem to be much better.

PS: the s15 injectors always seem to flow about 440 cc not 480

Definitely only 6-spd manual has the bigger injectors.

Check the part number to be sure.

Nissan Part No. 16600-91f00

Side feed

Terracotta Top Colour

Oval Plug

Impedence : 11 ohm

They do usually flow lower than 480cc when tested as the s15 fuel reg runs a slightly higher rail pressure than s13/s14/r33.

The whole JDM vs Aus-spec thing is a bit of urban myth. I recall seeing it written by a contributor to HPI + Zoom Mag a couple of years back.

Did my own research and found the parts numbers from Nissan the same regardless of which market they originated from.

Manual spec S15 = terracotta top = 440cc (or more dependent on rail pressure)

Auto spec S15 = purple top = 370cc

Can't believe all you read all the time, so do your own checks if in doubt.
