Do you ever pass 98RON through the tank? it's good to run 98RON every 10 tanks of E85 or so.

No-one told me this, and now I have gone and ruined my car... 5 years straight now. :/

and how do you go about doing that on an e85 tune?!!?!

I'm basing this on the assumption he has 2x tunes (which he might not).

Says who?

Five O Motorsports themselves and various other US based forums.

LOL... man you guys are digressing! I was saying to pass 98RON through the car every so often to keep the injectors happy.

Remember that these crappy highflow injectors are modified old tech sidefeeds that were designed in an era where high alcohol content fuels were nothing but a dream.

lol.... yes I am aware of that, but for some we just don't pour all our money into our cars and do what we can

But what has it cost you? In wasted time and hassle?

yeah and loads of swearing - if I "had" a NEO motor I would have just drop in modern top feeds and would have called it a day.

Dude I've got the same injectors as you haha

I heard good things from 2 people and thought they'd be sweet..... nahh

Yeah I wish I had one too. I swapped out a dead R33 motor for another 33 25 that I have now.

Didn't realise the huge benefits of running the R34 motor at the time, should have done that instead

higher lift stock cams, drop in top feeds, beefier factory bottom end.. drool

Drops a 34 Neo in because changing the fuel rail is just all too hard. :P

Yeah just read up on that if running e85 constantly injector tips tend to gum up and even gm commodore flex cars in the states got told to run a tank of pump 98 clears up the gum

I'm on single nistune map so e85 constantly but am going to just run a e85 fuels system cleaner now on with every oil change

If you change fuel filters often enough shouldn't have any problems, 3 years so far for me full time e85 and everything is clean fuel filters, injectors.

I agree, mine has never been apart since I shoved the 1000's in there 5 years ago. I would imagine the tips may have some black gunk around them, but it hasn't blocked the internal injector filter, and the 40 micron stainless filters obviously let it through without gumming up. I do run teflon fuel lines though, and I am a little worried the black gunk is from the stock rubber lines.

There are two choices, change your paper filter more often, or change to a slightly more coarse stainless 30-40 micron and hopefully forget about it.

Another thing, don't use the little filter in the top that fits into the adapters, unless you want to replace them regularly. They clog up with that black gunk quickly as the surface area is minimal. I have seen it a few times now.

Thanks for the tip. That is pretty crazy, I thought E85 should be cleaning the injectors since it made every thing else internally pretty clean. my daily driver KIA is on E85 all times and done 23,000KMs with it so far. I will pull it out for a check up this weekend.

Yeah worth the check but even injector cleaner isn't the best solution

Running a tank of normal unleaded dissolves this gunk and mainly affects city driven cars stop and go

But if you mainly do highway kms not as bad

Might just add 10-15l pump 98 to a tank of e85 at each oil change might run very rich but dissolve this goo

    • Just had this happen to me too.  R32 GTR.   Also broke "just before going out onto the track" - someone up there is looking out for us... Very scary since I was about to do a narrow street course with zero run-off and curbs everywhere. Many people on here upgrading to billet uprights and R35 bearings?   Or buying new OEM knuckles?  I am not keen to replace with another s/h 30 year old fatigued part.
    • Top off with distilled water and see what happens. If you keep losing coolant then you know to start looking.
    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
