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!

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
