Id Rb25 Injectors

[Strick.]

Gday everyone,

Can anyone ID RB25 injectors with numbers A46-200 and 0121517 on them?

They are red.

Thinking they are the standard ones, however want to make sure. if they are bigger than standard will have them flow tested and serviced.

cheers

sidefeeds yeah??

they are not standard, standard are a greyish colour.....what are they out of?

red injectors i know of include, S15 480cc, Nismo 740cc and pulsar 260cc...

they all look similar except nismos are more red where the others are maroon

maybe post some pics up

red!? could be sr20 injectors.

Standard had 2 diff colours. Grey and purple.

well they were all a greyish purple...probably depends which batch you got as to how much purple was in the mix

hmmm, a quick google search said they might be nismo 720 injectors but i didnt believe it.

Out of an R33 RB25.

i think i read somewhere siliva injectors can be used in these fuel rails?

Ive attached a pic this time.

[Plattsy]

they look like sr20 jectors'

i think they are 440cc?

but again, id be checking part numbers.

[Strick.]

[ARTZ]

f**kin wut?!

Had a look at the computer, looks like a standard one. Leading me to the fact that they must be standard injectors too!!

Although through all the searching im doing on A46-Z00 (the last number seems to be the batch number) is returning Nismo 740 injectors.

Guess ill have to get them flow tested to be sure!

More expensive way to deal with it, however i dont want to throw away 700 dollars worth of injectors that will suit what i need!

[ARTZ]

if ecu is stock they are not nismos. unless its got a nistune board in it or something and a46-z00 is pretty generic, its on all injectors of similar build regardless of size...its probably a batch number from the plastics casting company or something.....is it NA or turbo motor? more details on that would be more useful than any batch number

have a look here maybe. had a quick look but no match.

Its a turbo motor, it might have a computer without a sticker stating it does but i dont think so. The add did state it had upgraded injectors but i take that with a grain of salt!

Either way, they are being flow tested tomorrow. If they flow at 700 will give them a service and be all good. if not ill be in the market for some!!

Thanks for the help everyone, i thought there would be an easy way to ID these!

[ARTZ]

yeah hopefully they're Nismos man..GL

[Badgaz]

i'll guess nismo 740's let us know what they flow don't forget to get your pulse width measured if they can.

Heard back from the guys on thursday, I asked for a flow test on one first so it could be determined what they might flow before spending the money on a service and clean.

Came back with 100mil over 10 seconds meaning 600mil over 1 minute which all injectors are measured by. They are very gummed up and had bad fuel sitting in them.

Looks like they might be the Nismo 740s!! Great news. Also sheds light on why my car didnt start the other day.

So they will be cleaned and re-flowed next week and ill have a final figure.
