hey guys, I have an Rb 25 in my ceffie, and just recently every now and then seemably at random my motor just shits itself and looses power stalls, but if im quick and flick it into neutral and rev it a little, it will keep going as long as I don't let the revs drop to idle.

Now this little siezure will last about 30s to a minute whilst I think my car is dead and im looking for a spot to bail by the side of the road. I pull over keep it going or even let it stall, then a min later and it will start and drive perfectly like nothing ever happened.

It doesn't matter whether the motor is hot or cold but it only started in the last two weeks or so in this wet weather so I think that may have somthing to do with it.

Has anyone had anything similar happen with their Rb25s? I also noticed these tubes coming from the head have a little oil in them for the first time ever and this problem started cropping up - not my engine in pic and my tubes are clear hose thats why ican see there is oil in them. I thought they were oil breather hoses so i figure this is probably fine, but if anyone can correct me please do so! :D

Its the only way I'll learn...

I have EXACTLY the same thing happening to my RB20!! :confused:

I thought that it might be a f**kup when my immobiliser was installed, but now i'm not so sure. My immobiliser gets bypassed this wk so i'll find out then...

Gonna x-post this in the tech section for more coverage.

It seems to be a common issue with RB engines.......they tend to drop very low when you have come hard off the gas........i find by letting the vehicle slow down by braking against the engine will allow the system to sort itself out and remedy it.

Not uncommon. Someone once told me it was because of the GTR fuel pump.....not sure how correct that is.

i believe its something to do with the way the fuel pump is ground... one remedy is to re earth it to a better position or something... there should be a thread in the performance section related to it.

mine stalls all the time... but i dont have any BOVs lol

could also be something to do with the BOV... stock or aftermarket?

If it only happens when you give it a bit of full throttle or even just a bit of a push then completely come off the throttle then it is your BOV. If you have no bov or an aftermarket item then try going back to the stock plumback system. When i blocked off my blow off valve so i was running no bov this happened to me all the time, and after less than a week i gave up and put the stocko back on

This information may be completely irrelevant to your situation and i accept no responsibilities to anyones time that has been wasted

Thank you

on my rb25 i used to get it to stall when i put the clutch in for longer than a gearchange... was happening cos i wasnt running a bov... allowed to turbo to spin back the other way and it inst what the engine want, creates too much back pressure shuts down

Sorry to Hijack basket case. hopefully we can both get our RB's sorted :) glad it's not just me...

inark...I'll get my earth checked to my fuel pump (cause immobiliser was 3 point and included fuel pump).

Don't know about Basket Case but mine stalls at random. Cruising along a highway, cruising down the street. Slow decelleration coming to lights. and just like basket case, sometimes it'll start again straight away, and other times it'll take 3 mins to crank over again :(

remember this has only just started and has never been an issue before so it more than likely aint going to be the idle or timing...

just take it to be checked.

so your saying that the IAC valve(that controls the idle)cannot die?The timing check would also be a good idea...but make sure you have the correct procedure for your vehicle....ie some models you have to disconnect IAC valve/TPS

cheers

Hey! Woa, all these replies, I acually moved house so i have been without the net for a month - strange times for me...

I got an immobiliser installed a few weeks ago and got my custom turb manifold welded up coz it had a few cracks (thanks cef11e) and I was talkin to a mech about the idle (650RPM) and he assured me there was nothin to worry about with the ilde if it had been runnin' happily for 4 months like that.

Why im on the net at my local library now?

two days ago, :) the cef ran into so serious electrical fouls - It cuts out as soon as the motor warms up - Just cuts the fuel, pump the accel and it somtimes comes back and you can limp the car to a safe place to stop. Im guessing its a messed up temp sensor somewhere? which one who knows... I still get plenty of fuel pressure wich says its not a fuel delivery issue with the pump...

So 3 mechanics later and no one can figure it out - So im goin to shell out $$ getting it dyno checked by a perfomace mech with the right equipment to test the ecu. and hopefully all will be well again.

Thanks for all the replys! and I shoukd be a regular forumer in about a week when i get my new net connection hooked up!

Mine had the same problem and I use a head cleaners spray (for VHS players) on my AFM. Must be due to the HKS powerflow not blocking the dirt enough. After cleaning, pull my batt connectors out (to reset the CPU) then reconnect. Then start it up. Works wonders and car don't feel lag anymore.

    • Yeah, the latter. No diff should have a centre replaced without checking clearances because its unlikely to be the same as whatever came out. Not that that stops most people just checking a new centre in
    • Major thread necro but how bad of a job is it to DIY? Looking at it online it looks like if you reuse your ring and pinion as long as those are in good condition it should be fine to just pull the axles/front cover and replace the diff that way? Or should I be replacing everything and doing preload measurements/gear mesh testing like the factory service manual mentions for the rear diff?
    • in my list I had the R33 GTR as the best Skyline. Infact I had all GTR's (33>34=32), the NSX, the GTO, the 300ZX, the 180SX, the S15 better than the FD RX7. I had the MR2 and the A80 as 'just' better. I also think the DC5R Integra looks better but this is an 01 onwards car. I also think the FC>FD. It's almost like aesthetics are individual! The elements @GTSBoy likes about the FD and dislikes about the 180 are inverse in my eyes. I hate the rear end of the FD and it's weird tail lights that are bulbous and remind me of early hyundai excels. They are not striking, nor iconic, nor retro cool. The GTO has supercar proportions. I maintain these look much better in person (like the NSX) especially with nice wheels and suspension which is mandatory for all cars pretty much. Some (or all) of these you have to see in person to appreciate. You can't write a car off until you see one in the flesh IMO. Like most people we probably just like/dislike cars which represent certain eras of design or design styles in general. I also think the 60's Jag E type looks HORRIBLE, literally disgusting, and the 2000GT is nothing to write home about. FWIW I don't think the Dodge Viper Gen1's have aged very well either. You can probably see where I rate bubbly coupes like the FD. I know we're straying now but the C4 and C5 absolutely murder the Viper in the looks department as time goes on, for my eyes. Wouldn't surprise me if people who love the FD, also love the MX5, Dodge Viper, Jag E Type, etc etc.
    • I used to hate R31s, and any of the other Nissans that led up to it, and any of the Toyotas with similar styling, because of the boxiness. They were, and remain, childish, simplistic, and generally awful. I appreciate R31s a lot more now, but only the JDM 2 door. The ADM 4 door (and any other 4 door, even if they are unique compared to our local one) can eat a bowl of dicks. The Aussie R31 is also forever tarnished by their association with stereotypical bong clutching Aussie R31 owners of the 90s and early 2000s. I think the Nissans of the 70s (other than 120Y/180B/200B) are far superior looking to the 80s cars. The 240K era Skylines are boss. The same is broadly true of Toyotas. Hondas don't ever register in my thinking, from any era. Mitsus are all horrid shitboxen in any era, and so also don't register. Subarus are always awful, ditto. Daihatsus and Suzukis also don't generally register. They are all invisible. I think the SW20 MR2 looks fiddly. The 3000GT/GTO is like that but way worse. Too many silly plastic barnacles and fiddly gimmicks ruined what could have been a really nice base shape. Kinda-sorta looks like a big heavy ST165 Celica coupe (and I'm not sure if that's a good thing or a bad thing). I think the 180SX is dreadfully bland. It's not bad looking. But it has no excitement to it at all. It's just a liftback coupe thing with no interest in its lines, and bad graphical elements (ie wide expanses of taillight plastic on the rear garnish). The S13 Silvia is a little better - getting closer to R32 shapes. But still....bland. S14? Nope. Don't love it. S15...a little better. Probably a lot better, actually. Benefits from not being like a shrunk in the wash R34 (where the S13 was a shrunk in the wash R32 and the S14 looked like a Pulsar or something else from the stable on Nissan mid 90s horrors). The Z32 was hot as f**k when it came out but hasn't aged as well as the A80. Keep in mind that I think the R33 is the most disgusting looking thing - and out of all the previous cars mentioned is objectively closest to my precious R32. It's just....real bad, almost everywhere you look. And that is down to the majority of what was designed in the 90s being shit. All Nissans from that era look like shit. Most other brands ditto. In that context, the FD absolutely stands out as being by far the best looking car, for reasons already discussed. Going behind the aesthetics, the suspension alone makes it better than almost any other car.
