Do you have any form of aftermarket CDI? eg HKS Twin power?

If it is indeed your alternator then it's not a massive job, though i've never had one fail personally its bound to go through enough wear and tear to eventually give up.

yeh but wouldnt that like turn the car off... make me loose lighting and make my headunit play up aswell??

or is there like a seperate part which runs to the ecu..

most of the times the battery light will come on, on the dash, or it will have a loud wurr to it... and the charge rate will drop to battery voltate eg. 12.6 or 12.8. if diodes are gone charge rate my be normal but untill you put lights ect on, will drop down to 13v or something... never realy seen one have any problems with supplying spark, cuz if it gets spark ecu is doing its job... how well known is your mechanic? as might be time to change... never seen an alternator do anything like what your sayen on any car.. weather it be ford, holden, nissan, subaru, mazada, ect..

i had the same symptom you have when i had my air flow meter disconnected, only as i had to get home, only with the airflow meter hooked up, it cut out and ran like shit.... my problem was that my engine was farked after it was majorly overheated but ran fine 70% of the time rb25det s2 though? dunno what yours is havent read your updates

hes just a normal mechanic down the road from me. not a specialist in imports or anything. I dont think its the alternator... i really dont, but he has one of those Snap-on error detector thingos, and its readying a problem with the signals to the ecu or sumshit... so im not to sure wats going on, if this doesnt solve it ill take it to marty when hes off holidays. Probably a good thing i changed the cam angle sensor anyway, its was sooooo f**ked haha both bearings where ceased and the disk and sensor where both f**ked.

i kno its so fkd. I havnt tried the ecu thing yet, would one from a rb25de neo be the same, i got a mate with a 34... or one from a rb20de?

are they all simular?

update: he said it is the alternator playing up... now i dont see how this would be the case, he recons it isnt giving enough to the computer or ecu, and that isnt able to support the igniter pack and all that... wtf?

i was checking ur gtr out today daz :rolleyes: cus my cars at yates automotive across the road there.

yeah, well im sure the ecu's are model specific, so i would try find somebody with an n/a RB25de r33/r32 (depends on what model your motor is) and try there ecu if u want to try that. but yeah unless you have diagnostic equipment to plug in, your just going to be guessing if its something more serious then all of the things i have described.

yeh the mechanic is using a snapon computer thing. If he cant fix it with this alternator thing he recons it is, im ganna go thru the elemination process on the smaller things, like loom, afm, so on as you said daz but then if im still lost ... ill take it to a specialist in this area.

i just spoke to my old boy then he went and saw my car today when i was at work.

the mechanic said when he disconnected the alternator... the missfire wasnt present... car went well, when he hooked it up there was a miss.. he said the alternator is working but having peaks of power. and the ecu is like wtf? and losses it for abit, that when the problem comes ... but stil im not convinced.

Also the miss gets smaller and smaller the warmer the car gets.. he redlined it today after it had been running for awhile, and there was a very minor misfire at like 6500.... when its cost it can rev over 1500-2000 without jerking around.

WTF i just wont this shit to fk off haha

ok legend... sorry i didn't know it was a spelling test/English lesson, next time ill be prepared for hilarious sarcasm.

Like 90% of the comments i see from you are all pathetic sarcastic calls mate. legend..

Can you pm me your mobile number please?

I'm Trying to work out which turbo set up I want and I'm looking at a 3582r in .63 housing

Just wanted to talk to you as I believe you have the same set up??? And see what your thoughts on it were. :blush:

WooHoo!!!!! I got my full open bike licence today!!!! I have been out riding for about 3 hours on my cbr600 and my ass is killing me hahaha. Awesome though.

If anyone is keen for a run up the hills or something let me know!

    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go       
    • I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
