[R33ram]

Hi,

just need to know whta injectors i have as was told 550cc when bought the car but not sure.I no there red and only pic i could take was engine which doesnt show much.

thought maybe the colour and side feed i think they are can give me a bit of info to tell but not sure...

any help or opinions would be great

I bought 550cc Nismo injectors last week and they are also red.. But I know that 550cc come in purple also if I'm correct.

[R33ram]

yea thats i was told i had but wasnt to sure. the 555cc nismo ones are yellow and the 740cc ones are red.

Take off one of the metal cap things and post what numbers are cast into the top of the injectors.

The Nismo 555cc Top Feed injectors I have are pink.

The Nismo 555cc Top Feed injectors I have are pink.

Top Feed =/= Side Feed.

Top Feed =/= Side Feed.

Yes, I missed that he said side feed, so I was sure to mention which mine were as I wasn't sure about the ones in question.

[jjman]

yeah the nismo 550 side feeds are yellow.

Well if you open up your ecu won't it tell you what size they are, or is it not tuned yet?

[cherring]

Maybe you have these if you have nismo ones.

They could also be S14 480cc injectors. Really though the easiest way to tell is to take one of the covers off and look up the model code.

[R33ram]

Took off the cover and found the code>>>A46-00 on one side and on the other side 5655-921

a46-00 from what I can work out are 245cc injectors. Most likely they've been highflowed at some point.

[R33ram]

how the hell did i make 250kw lol with those then,i was told 550cc but dnt know,have to be hi flowed no doubt about that

[Miguelone]

I'm not entirely certain though. I have a set of injectors here stamped with A46-00 which aren't bright red more of a maroon colour which I bought believing they were S15 480cc's. Have yet to have them flow tested though so unsure what they are.

They're not nismos, as your running aftermarket plugs and the nismo 740 side feeds are a direct fit, same as the s15 480s .I have sard 550 side feeds that are red but they have the Denso imprint and a serial number, they could be jecs, or no offense eBay specials.

Those plugs look standard to me...
