i got a set of freshly recon'd 550cc purple tops off ebay and just wondering if any one knows much about them. i have heard if your fuel is rich in ethanol it can cause damage. i only every put 98 octane in my car so will this be a problem??? anyone with a set? im hoping that it is just an over exageration

What motor is this going on? NEO or R33 RB25?

And no ethanol does not harm injectors. (forgot to answer this earlier) The mythology is, that ethanol corrodes old fuel lines. Realistically this is a non event for most skyline users anyway, really only a variable if you run an E85 setup, and even then there arent THAT many rubber hoses to replace in the car anyway.

What colour is std, I thought purple was std???

Mines a '98 R33 and I've got yellow tops= nismo 555's and they flow like that as well - they were on the car already from Japan, but I'm sure that purple tops were the std colour in '98 rb25's??

Purple is stocko for RB25, but it looks to be a different purple again lol.

If I were you, the risk is too big, why muck around with all that. Snap up a second hand set of nismo 555s or 740s for 700 bucks, plug and play.

They are top feed injectors in the pics. They are definitely not stock RB25DET side feed injectors regardless of the colour.

On another note, I had Denso 550cc injectors in my GTR when I first bought it and I'm pretty sure they were purple!

    • Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.  
    • Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?
    • Hey mate,  I have a set, one is slightly damaged but wont be noticable once installed.  Shoot me a message if your still after them 
    • I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
