I would suspect the tensioner bearings for the noise first and belt (as in belt not fitting the gears neatly) second, more than likely the warn/loose old belt has reduced the tension on the tensioner bearings etc and now that you have put a new belt on it is highlighting a problem that was already there - due to the extra tension on the bearings. Another thing that may be contributing to the noise could be the extra strength the blue gates belt has/retains over the std belt, to me this would make sense that the belt must be less stretchy than the std and therefore this would also mean the bearings are being submitted to extra tension and cause any wear in them to be more easily noticed.

I have used Gates belts on a few engine rebuilds in the past and never had a problem with any of them. If replacing the bearings doesn't fix the noise and your gears are in good condition(i.e. no obvious damage) then I would be making a complaint to Gates directly, I am sure their engineers would be interested if there was a problem i.e. belts not meshing fully with a cam/crank gear...

There should not be an issue of the Gates belts not fitting in the cam gears. Gates make the majority of OEM timing belts for cars around the world (about 70%) so quality won't be an issue. I tend to agree with the gts4diehard, the racing timing belt is stronger and will not stretch as much as the original. This may mean that it requires a different tension to the original.

I would love to know if anyone has an actual figure of what the tension should be for the timing belt. I have the service manual and it just says something like "tension timing belt to the correct tension". That is pretty usless info as I can't find anywhere what the correct tension is. It has the tensions for the accessories belts but not the timing one.. stupid.

I had my timing belt changed to a gates racing belt by a tuning shop and it hums intermitently. I also had the tensioner, idler, adjustable ex cam gear, and water pump changed at the same time. It is no good that so many people have experienced this.

So some of u r suggesting to throw away a good belt that is brand new and freshly put on the engine... Big deal it makes a bit of a noise. Save urselves the embarressment at lights and sell ur R33 :).. If any1 asks u have a gates timing belt, most of the bogans next to u in the VN commodores would be impressed by that if u bought ur car to impress other ppl. From the read it sounds like it is very common with the gates belts. I am just getting one installed myself by a workshop who use them on track cars... If they were that shit I don't they would be used for track purposes on pretty modded engines.

      Yes...but look at the numbers. There is a tiny tiny fraction of the number of Joules available, compared to what is used/needed. Just because things are "possible" doesn't make them meaningful.

      Somehow Vertimass/Oak Ridge National Labs has figured out a catalyst that can convert ethanol into C9-C10 hydrocarbons in basically a single step without ending up with a bunch of ethylene or similar waste products: https://patents.google.com/patent/WO2023224867A1/en I still don't think anything like this will keep us from needing to transition to EVs regardless along with all kinds of other electrification, but things like this will go a long way towards alleviating the problem of how to electrify things like planes. Renewable diesel is seemingly an easier problem as well, Chevron is already running refineries for the stuff and the primary feedstock is tallow and other waste fats from agriculture.

      Ok so I have sorted everything with my uniclutch and  i can offer up a bit of feedback and some things that might help others.    I found problems with factory damper line. Weird shit and had trouble with peddle adjustment    I used this https://au.gktech.com/products/r33-gts-t-skyline-braided-clutch-line?_pos=2&_sid=22b01b9b9&_ss=r Also when adjusting peddle leave a bit of play. You can get into a over stroke condition easy.. Make sure you can push the slave forward after adjusting to confirm fluid can return to master then you will need to pump it up heaps…..not sure why but that’s how it is.    last thing the splined adapter is machined perfectly. If your input shaft is old like mine was I would put a bit of valve grinding paste on it and stroke it like a 15 year old. Just to give it a tad more clearance and to better match it to the spline.    reason is on a near flat shift I have had situation where the peddle returns a millisecond after you lift from the clutch. No slip or anything but I reckon this is due to tolerance on the spline being way tighter than stock clutch and binding for a sec. I think this will go away but also my spline was old. Box is old so I guess I should have checked better. It’s a super neat fit.    it feels light as and holds awesome without any noise
