hey guys

well I've had this issue for a short while now..

It sounds much like a loose pas/alt belt but louder. Its also not throttle related - sometimes I can fire it up from cold and it'll sit there and do it for 30seconds and other times I can drive for 20km and have not so much as a whisper then it'll just do it again.

I've tried wd40 on both belts it did nothing so I'm guessing its not a belt related issue.

I tried today to remove the pas belt and it the sound didn't appear once (steering was bloody tough tho lol!). once I put the pas belt back on and nipped it up I heard the screech again.

Has anyone had this issue? Would overtightening the pas pump belt cause it to screech at all?

sorry for the questions, the car still seems ok but the noise is just driving me nuts now lol!

When a belt starts to slip after working for a long time, i reckon it should be replaced. Also, belts need to grip - screeching is them slipping, so putting on a lubricant like WD40 will just make the slipping problem worse. I wouldnt expect it to be bearing, as that noise will be consistent not coming and going as you're seeing. Overtighening usually just makes bearings wear faster - AFAIK it cant cause screeching.

Have you checked the PS fluid level? (not that I would expect that to make the noise you described, but i dont have any good ideas).

      Comfortable replacement seats for R32 GTR

      By Murray_Calavera · Posted

      As strange as this sounds (as they are fixed back), my Bride Xero CS seats are the most comfortable seats I've used.  I vote go genuine.  The only downside I've found is on very long drives, you can't reposition your body while driving. So even though its comfy, being locked in the same position eventually becomes uncomfortable. I find myself stopping every 3 or so hours to stretch my legs on long drives.

      You don't have to be bored driving a Camry. Not based on the way that a couple of f**king Ubereats/Didi/othersortofmethaddlednightshiftattheservicestationrecentimmmigrants were piloting them on the way to work this morning. f**k me dead!

      FWIW, the Bride reps are really nice to sit in. The only complaint I have, other than the tear in my bolster, is that the velcro used to hold the backrest cushion in place, up under the headrest, is a little obvious and intrusive and could probably be done better. I don't know if that is a "feature" on the genuine ones also though. I haven't looked at a genuine one like the ones I have, only some of the older models. The other thing is, even though I bought the CF ones, I think the CF is really just decorative, over the top of the same FG as the normal seats. And so they really aren't light. Between the solidly built CF/FG seat, the steel frame in the recliner mechanism, and the solid-arse seat rail, they are probably heavier than even the stock seat. They are a serious lift to get in and out of the car.

      Yes, and so the barest minimum power target is the one that makes the most sense. Massive power is fun, but you can only use it for 1.5s at a time, and only every now and then. Medium power levels allow you to enjoy the car far more often and for longer. 500 engine HP is just below 300 rwkW which is about the maximum that is sensible for any street car really. And for a 2.6L six, it will still leave you with a decent boost response and some sort of linearity of power delivery. As you get up towards 400rwkW the onset of power tends to be increasingly like a cliff and you need drag radials to keep the ground in proper contact with the car, and.... it's just not a car for driving around any more.

      I already reached that conclusion myself after reading up a whole bunch and watching various videos from multiple sources. Don't know yet how I'd best manage that with the least amount of headache. Probably pulling the sump and just welding on a AN10 adapter or something. I also think it's healthy to take most opinions with a grain of salt, because experiences differ wildly and especially Aussies - when talking about RBs - don't know a world below 600whp drag builds. Personally I doubt I will ever take my R33 racing, so it's going to be a street car with the occasional spirited drive. Hence why I am (so far) under the impression that I'm going to be fine with a stock-ish engine for a while.
