Someone else on another forum having the same problem, only he worked out how to fix it... power steering pulley was on the piss! Worth checking. http://www.gtr.co.uk/forum/241625-pas-belts-flying-o

mmm.. glad he fixed it. but in my case I am 110% sure this was not the issue. Went to great lengths to ensure it was perfectly lined up and straight. Even bought a laser alignment tool just to be

Do you mean the pulley's are not at the correct offset for the pump?

Or the V grooves have incorrect angles, or are to shallow or deep?

More info please.

The offset was off using a 25 pump and bracket on a 30.

Oh so you mean you used a balancer that is designed as a factory fitment but put it in an application that it was unintended for?

Is anyone having a problem with a 25 balancer on an RB25 or a 26 balancer on an RB26?

I'm having a problem using a 26 balancer with 26 power steerin pump and bracket on a 2630. Bear in mind this problem did not exist when using the ATI. Mark Berry had same problem.

Piggaz also was having same issue which I think was 33 balancer on RB26 (2.8) with correct power steering pump etc. No prob prior to fitment either. Correct Paul?

I was having a few issues with this flicking off PS belt thingo. We made sure everything was "square", IE the PS pump/bracket was spot on and I also fitted the idler pulley thing for the belt. Problem went away. Car will be back on the road soon so I'll be able to report back.

If the pulley is underdriven u need a smaller belt. Even my ATI spat a belt. I put a smaller belt on one that only just went on with ps fully loosened off and no probes now. try get as close to the crank as u can that's what I think.

They're the same size as standard.

Were you using a 25 balancer or a 30 balancer?

I believe it was a 30 one.

But don't quote me on that.

I was pissed it happened, BUT, these things happen when you are using different parts from 3 different engines, I like to call it teething problems.

I'm using a ross rb25 balancer with rb25 pump with their idler pulley kit and aligning the pump as per Ross's instructions and still throwing belts. it was never a problem before the new balancer so there must be something going on

Get a straight edge and run it from the balancer to the PS, I found the difference to be about 5mm, we drilled out the bracket so the whole PS assembly could move forward 5mm, the job took a couple of hours to do but now the 2 pulleys align perfectly.

And it was only the PS that was causing issues, the AC and ALT are fine.

Give ROSS a call and see what they say, its a common problem, albeit a easy fix if you modify the bracket.

Something is really wrong if your throwing belts with the idler pulley kit...

More elaboration, I can confirm that on the track I failed to spit the powersteering belt again. Mine is rb25, limiter 7700, to recap on the mods I did to help, I machined front lip of p/s section down to 1mm over belt height, and beadblasted all the anodising off the belt grooves, and refitted using a new gates racing belt. Time will tell if its a confirmed win

That's good news Amon.

I asked Ross some months back if he thought it could be the coating - as he insisted there was no difference (measured up) between the ATI and the ROSS. I wonder if perhaps the anodising is somehow making it "grip up" ?

Mine already had been machined down from Ross - this is something they had already struck apparently. Interesting that yours which I assume is not as old as mine, still had the lip...

Yeah iv only had mine since the start of this thread. could of been old stock... I recon the anodising makes the belt intermittantly slip and grab and create a flicking of the belt. Might be wrong. whereas the blasted pulley is very grippy and consistent

I am coming down to the nit and gritty part of my build, and saving the power steering belt issue for last. I have run a dry sump oil system on my RB26/30 build and I cannot risk having this issue, so I am going to correct/fix the issue first, before it even becomes a problem. (save the "If it ain't broke, don't fix it" comments please). I don't want to have a catastrophic engine failure due to an f**king power steering belt.

I am running my 2 year old RB26 Ross Dampener on my RB26/30 build, don't see a problem using it. I am either looking into the Ross Idler Kit, or this other kit they have.

http://blog.rossperformanceparts.com/category/engine-protection-kits/nissan-rb26/

Anyone running a dry sump have experience with this type of set-up? Anyone see any issues running this kit? Any input would be greatly appreciated.....

If not, then just to avoid the whole issue, I am gonna run a Volvo Electric Power steering pump.......

I've done a couple of HTD driven steering pumps with Ross

Never had a single drama with them. Slows the steering pump to 50% (or whatever speed you choose to gear it) perfect drive and never had a belt come off. After we fitted the first kit and made some recommendations to Ross I believe he has refined the setup and is supplying some specific fittings and spacers that are needed now.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      By Duncan · Posted

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
