Hi all, tried posting in newb esection, nlooks like no one goes there. I'm looking to buy a Stagea and have been told the following (see discussion below). Can you please advise how accurate this comment is? It suprised that a cam chain would require the same service intervals as a belt...

"..why would it have a new cam chain installed??..especially after 87K kms. Is there a full engine history to prove that there has been no engine damage? ..."Hi the Stagea Engine has a cam chain in it which is very long in length and over time it stretches and makes a noise being abit lose the hydric tensioner over time maxes out and this is why new ones need to be installed all of them will need it done at one stage or another usually around 100km that is why all of them I import usually get done. 9:49 am, Mon 25 Jul

"But, the whole point of the chain is that it does not need to be changed at usual cam belt intervals. If tensioners are failing oil changes must have been irregular"..." Well, Not sure your under standing, cam chains were never designed to never be changed, they were designed never to snap.Being a v6 this chain is twice the length of an ordaining chain thus it will stretch and coarse the timing to go out which in turn make the car run not to factory setting and Tensioners do not fail .. 2:34 pm, Mon 25 Jul

that is assuming the tensioner mechanisim is lubricated by engine oil circulation. Anyway thanks for answering..." Best thing is to go buy any Stagea in NZ which has not had the cam chain done and wait to under stand what I am talking about being ive had over 12 done as it is common practice with them..

so whats the deal on chain vs belt? :)

im assuming youre talking about the M35 VQ equipped engine?

if you ever have to change the timing chain in the life of the car, id be very surprised. that means someone didnt change the oil. ever.

the chain will stretch yes, but they have a tensioner to take up the slack.

youll never have to change it.

I know its not Stagea, but I had an RMR30 that did 600ks on the original chain. Currently running an MR30 with 300Ks. The chains never seem to wear out with regular service.

As the others have said, you shouldn't need to change a chain.

I have over 220,000kms on my M35 Stagea and never had the chain changed.

"100,000km change-over" is for timing belts on the RB powered C34 Stagea's.

As an aside, an engine with a timing chain will be noisier than one with a belt.

Cant be any harder than an SR20 lol

the main reason I stopped posting in here is because of all the idiots that dont know their arse from their elbow giving bullshit advice that will lead any unsuspecting noob to really stuff things up. The above posts confirm how right I was

The chains never seem to wear out with regular service.

Hugh, once again, your talents and experience are wasted on these idiots, but thank you for giving me hope that this forum is not totally slowly morphing into a petri dish of retards, window lickers and mouth breathers, challenged only in size by the commenters on youtube.

Thanks to all of you. I know everyone has varying levels of hands-on experience and skills, so I appreciate all feedback and accept that not always 100% accurate. Looks like the dealer I quoted was talking through his reear-end LOL...no suprise there :)

Please excuse our idiocity your highness.

Nice of you to take the time to post such a helpful post.

Now if you don't mind, I have to get back to searching for a belt drive that is noisier than a chain drive.

Then continue to not post in here?

My last comment about the SR20 was a joke, so how about you get your head out of your ass?

Ah what up hater!

And I also see a trend in here of ongoing personal attacks between the owners of 2 models of cars, not to mention far too many threads deteriorating into shit fights, or going so far off topic no-one whould ever guess what the original topic was

The purpose of this forum is to share information and experience on Stageas, not to practice arguing on the internet. Plenty of other places you can try that. And anyone that feel the needs to just talk about random off topic stuff already has a whore thread here to do that in. http://www.skylinesaustralia.com/forums/topic/342557-this-is-the-new-recipe-chat-thread/

So how about every grows up a little so I don't have to go on a banning spree again? Particularly the "senior" members who have been here a while, how about you focus on creating a positive community, and welcoming new people to it.

Please try to stay on topic Duncan. :P

The only time I changed a noisy chain it was a failed tensioner, much more common than you think for a mechanical spring style tensioner to fail, hydraulic ones I have never seen a problem with.

and what tensioner is in a VQ engine??

SR20s had a problem when you used oil too thick, or thin, i cant remember which. and the chain rattled on startup and idle. sounded like a diesel lol

im glad the VQ doesnt do that!

      GReddy Injector Help!

      By ChoppedSpots · Posted

      Thanks for the reply, So i've continued playing around, and fitted the injector adaptors onto the injector, the fuel rail is not able to be mounted now as the injectors sit a bit further out. I suppose the point of the adaptors is so that the injector nozzle isn't so deep into the intake? I suppose 1mm extra on the o-ring would do it but still can't mount the rail onto the intake haha. Waiting on a reply from Aeroflow I'm sure there's something stupid that I'm missing...

      GReddy Injector Help!

      By TurboTapin · Posted

      I have a radium fuel rail on my Greddy manifold and used the supplied radium fuel injector to manifold adapters (The round green things pictured). I did always wonder if you could just go ahead and use the second lower hole like you're doing... Wouldn't thicker o-rings solve your issue?

      From what I've seen and experienced first hand with those powder extinguishers, they're good to use to break a window and escape the car, and half the time then do f**k all to stop a fire. You just need much more than 1KG worth of powder. Not to mention, half the time it's an engine bay fire, and you can't easily, and do not want to completely open the bonnet, so you're left pretending to be an American Infantry... Spray and Pray baby!   And then 100% that shit is really destructive afterwards!   Realistically, those little ones at a race track might help you keep the fire from growing and give the fire marshal / truck a chance to actually get to you with their multiple large bottles.   For a road car, these days, prepare to deboard as quickly as humanly possible, and move to safety. Allow insurance to fix replace it (unless it's like a rare classic etc, then do nearly everything possible to save it!) Keep the little extinguisher with you to help protect other things around you from burning while you stand there singing "How can we sleep while our beds are burning?"   Secondly, powder extinguishers I freaking hate for indoor use, (this isn't really relevant to a car) as you will get a powder fog around you, and it can be disorientating.   When I did fire training when at BlueScope Steel, they have (had?) their own fire brigade on site. We did all the training, and at the end we were told, "If it's an indoor fire, and you need to use a powder extinguisher, we as the fire brigade would rather you just exit the building, you're more likely to get lost in the smoke and powder fog than do much help, so just GTFO" And pretty much that was what they said for most other fires too, grab extinguisher, if it's much more than paper in a bin fire, use extinguisher to get you and others out of the building to safety...   Part of me wishes when my Skyline caught alight many moons ago, I let insurance sort it out, instead of putting the fire out... part of me now says "But I've saved a classic before it was a classic!"

      GReddy Injector Help!

      By ChoppedSpots · Posted

      Hi all,  I have a older model of the Greddy Front facing intake on an RB25DET NEO Head. I've bought aeroflows fuel rail and injector kit (1000cc Bosche injectors) and I'm unsure if the fitment is correct. The injector o-rings fit in the intake hole but it's not snug. I can very easily rotate the injectors even when the fuel rail is mounted. The kit also came with multiple adaptors, they dont make it any more snug and using them raises the injectors up and i cant mount the fuel rail. I hope this makes sense I've asses a few photos.    Thanks so much guys.
