Rb26 Noise At Low Revs

Hi Guys,

Dunno why I didn't post this question earlier. I have a Stagea 260RS, which I've owned for over 2 years. One thing I've always noticed with this car is that the engine kinda makes a rattley/rumbly sorta noise at low RPM (perhaps 2000rpm). It's hard to explain, but it sounds like it's sorta labouring. It's not pinging, I've heard pinging before and it sounds nothing like it. It's a lower frequency rumbling sorta noise. Perhaps it's the body kit or something resonating at that frequency. Maybe the exhaust. I dunno. Has anyone else noticed this? Is it a normal RB26 thing? I've never had an RB26 before this, so have nothing to compare against.

This noise has been there since I bought the car and I'ver never been overly concerned about it. Over the last few years I have replaced the ECU with a Vipec, fixed a leaking inlet manifold gasket and done the 100k service kit. I've checked compression twice. The last time was 18 months ago and got 180+ in each cylinder and 160 something in cylinder 6. Any ideas?

Mate i think i have the same thing. Bought it like that.

At first i thought it was my airbox resonating since its a loose. I currently suspect it may be the intake pipe not being fully seated on the turbo. Although the car does sound like its struggling....i don't think it is as it doesn't feel like your typical lugging.

The sound I get emanates from the passenger side - front quarter. Let me know what it is if you find out! At the moment I don't have my tools on me to take it apart to ensure everything checks out.

Same thing here . . . Recently purchased a Stagea 260RS and noticed the same noise described above. This is the first RB26 I've owned or driven, so I cannot compare to much. Like @tranman said, the car sounds like it's struggling, but feels fine. And indeed the noise does sound like it's coming from the front/passenger side.

Anyone ever find out what the cause is?

I ended up selling my stagea a couple of months ago. It still has the noise. A couple of mechanics looked at it and didn't think it was anything to worry about. I just bought an R32 GTR that makes a similar noise, but much quieter. I'm pretty sure it's the throwout bearing. Try pushing the clutch in when you hear the noise.

I've spoken to a mechanic/importer who deals with a lot of GTRs. He wasn't sure about where exactly the noise is coming from, but said this is very common in GTRs (and the 260RS) and it's nothing to worry about.

I've recently driven a second 260RS (stock engine and exhaust) with an aftermarket clutch and it did not make the noise. So it could indeed be coming from the clutch/flywheel area as suggested above. If I push the clutch once the noise comes on it does go away.

      And if you want more power, more reliably, and cheaper, go get the Aussie RB... The 4L Barra and put that in instead.

      No cats will keep discolouring the rear bar. Sends white paint a weird yellow stain. Cut and polish normally gets it out, but you'll be doing that every fortnight I found.

      Both heads will be equally reliable or unreliable depending on what you do to them.  Stock the RB26 head will flow more. You have access to the stock intake ITB manifold on the RB26 cheaply which flows really well(1000hp+).   Arguably more aftermarket support for RB26, though in Aus we love our RB30 SOHC heads too.    The only downsides to the RB26 head is if you have a VL commodore and want to keep the SOHC look.  Where you may have an issue is drilling out the rb30 block for the bigger head studs but if you are building a big power motor you'd probably put bigger studs on the SOHC head too.  This is just about finding a good machine shop, sometimes easier said than done.  RB30 head worked can make big power just like a Rb26 head, so really it actually more comes down to what your preference is for your car.  People now even making billet versions of both.

      2630s work perfectly well. There is something to be said for just using the 30 head, as it saves all the pain of the conversion, still makes tons of power, still sounds cool, etc etc. 2630 will obviously make more power again, but the differences are not stupidly big. It really depends on whether you're racing for sheep stations or not. If it's dead serious, then it's a 26 head. If it's just for fun, it could go either way. But the 26 head and the effort to get it set up, etc etc, is part of the fun.

      I've been building a 26/30 for a few years now. I've had the head built with all the good stuff. I had a 32 gtr but blew it up and yes its all going into a vl but im looking for some advice from some RB nuts on pros and cons on putting a 26 head on a 30 bottom end is it worth it Works are as follows Head -Extensive porting 1mm oversized supertech valves Supertech double springs Supertech valve guides Supertech titanium retainers Tomei solid lifters Tomei 270 x 10.25 cams Head drain Bottom end series 2 rb30 block Cp ceramic coated pistons Eagle rods Romac balancer Oil restrictions  O ringed blah blah spent a fortune And will get a girdle because the 30s arent used to handling that much rpm Nitto billet oil pump Hypertune plenum 6boost mani Refurbed astra pump thats the cover for it in the boot I did have a precision 6262 but sold it because drag car life. Currently building the ass end full 4 link floater rear end with a 2 speed  But the dilemma i have is my mate rekens I should just stick with the 30 head for reliability. Has any one had any issues with mounting the 26 head ie compression blowing gaskets etc. Just looking for some advice from people who have gone down this route. Here's some photos. Blew the oil pump in the gtr and decided to rip the motor out at the time and do a full build only to find it had been a repairable write off so went down this path.
