I had a Gates installed on Thursday. Today I noticed an annoying amount of noise, so I thought I would look on the forum to see if it's common.

"i have heard of people complaining that the gates belts are quite noisy... "

Well, there you go... :(

word up, i agree stocker oem item should be fine, brand prolly doesnt mean. to have timing belt changed is usually around $450 in labour. as have you basically pull heaps of crap out of the way to get it done

Hi, just wondering what sort of noise people are hearing with Gates belts?

I had a nissan belt on my R32(when Nissan were about the only choice available here) and it was quiet, the only noise that came from area was the squeak/whirring sound from the worn out tensioner bearing before I replaced it. I have a Gates on my R31 and it makes no noise.

Gates have made good quality belts for a very long time, my old man always used them on the engines he rebuilt. Possibly some of the noise being heard now could be tensioner bearings. The only other ways a belt can make a noise is if the teeth on it are slightly different profile(i.e. gears worn or belt profile not matching) to that on the cam/crank gears or its rubbing on the guard because it isn't dentralised on the gears.

I seriously doubt that Nissan or HKS make its own belts so they will be coming from a parts supplier like Gates anyway.

The noise I have is a whirring noise. After listening to it again tonight, I think you might be on the money with tooth profile or something similar. I have a Gates belt and new OS Giken gears. Perhaps you wouldn't get the noise with the original gears???

    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂
