hey guys my rb20 is making a high pitch humming noise at idle and it seem to pulse in and out and it sounds like its getting worse, it definietly sounds like its coming from the front of the engine.

the only thing i can think of is maybe one of the belts is to tight?

any help is much appreciated.

cheers,

tim

Probably belt tension, it comes and go after you rev it up isn't it? too loose or too tight will make noise.

Keep in mind that belts do stretch over time and when they do, sometimes they make that kind of noise.

      Eibach wheel spacer

      By drifter17a · Posted

      Hi    have purchased pair of eibach wheel spacer as I couldn’t fit set of wheels I bought for my car due to it catching caliper.   I know I need to cut the bolts on my discs so they sit flush with the nut supplied but the nut doesn’t sit all the way into the groove meaning wheel would not directly fit onto the spacer rather the nuts. Any thoughts?   See pic   https://ibb.co/VJK5w5G

      Nah. There's not shit tonnes of pressure in there. Just drill with a 1.5mm drill or something equally tiny. When the drill goes all the way through thee gas will start to come out, but with such tiny path through the flutes of the drill bit, it won't be at all dangerous. You can be as paranoid as you like from then on. I'd just pull the drill out while keeping my face out of the line of fire. But then, I spend half my time looking into pressurised furnaces. So my risk acceptance is somewhat higher than most!

      Been needing a new clutch for a while, but holding off because of life tingz and adulting. But... Being of Asian descent, I can't pass on a good sale, especially everyone else is selling it for $2k+ (JJR has it for $1799). Really on the fence on this one, because the unsprung version of this is $1281 via Shitbox (Sparesbox) and the sprung version is quite a bit more (no idea why Shitbox doesn't offer them). Ending up just sending it and getting the twin sprung organic. Mainly because I wanted the car to be nice to drive and didn't want to make it more of a shitbox than it already is.
