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

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.

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!

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

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!

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.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
