Hi,

I am a noobie to the whole skyline scene. This might be a stupid question but I have to ask.

Is it normal for the release bearing to make singing sound when the car is idling, because when you put your foot on the clutch, it goes away. When you release you get this singing sound. I was told this is normal and just need some piece of mind.

Car: R32 Gts-t (92)

Any info will be greatly appreciated.

Thanks

Mine's been doing it for a while now. Started making the noise a few months after i replaced it. I haven't really worried about it and it hasn't caused any problems, but i will replace it next time the gearbox is out.

If it's the throwout (thrust) bearing it will be noisy when the clutch is engaged.

If the noise occurs when the clutch is disengaged, then subsides when the clutch is engaged it is more often than likely your output shaft bearing.

im sorry guys but your all horribly wrong..(apart from you 2lv8 you partly correct) the thrust brg will only make a noise when the clutch is ENGAGED as it only spins when its up against the pressure plate.

The noise you are hearing is a very common noise with the 32's, its the bearings on the main shaft in the centre housing your selector shafts run through of your gearbox. Only way you will get rid of it is putting a bearing kit through the gearbox. Just replacing the input shaft bearing will most likely not fix the noise completly

wait til it starts clunking when the bearings start moving about in the cage, then worry about it which depending on how its been driven will be about 200K Km. Drain your gearbox oil you will most likely find shavings.

If you buy a S/H 20 gearbox you will be buying the same problem

That's what I said......

A few times I've come across this issue and it was the input shaft bearing. It sounds like a straight cut set when you drive the car.

Either way, if he leaves it too long he'll have issues.

So what do you guys suggest I do, and how much will it cost coz I'm running on a tight budget this month.

Also the guy I spoke to said that the is like that, but like I said before I'm a complete noob to the skyline scene. I used to have an exel before, so yeah...the more info the better.

If you know what you're doing, crack it open and install a bearing kit through it.

If you don't know what you're doing, get a quote from a reputable mechanic and weigh the costs against installing a second hand box from a wrecker. Make sure you have some sort of return warranty in case the box is stuffed.

If you have a mate who can help you, you should be able to do it yourself for zero cost.

you dont need to go OEM... I ordered mine from WA DRIVE, Most brgs are Koyo and some bits n pc's genuine.. u can get a half kit cheap... which is just main shaft & input shaft brgs (not gear rollers) I went the whole hog but not about to disclose the cheap price i payed through work.

i got all the main bearing's for my box for $90 i think theres 6-7?? the one that was f**ked was the main shaft bearing in the carrier plate...

anyway i stripped the box down almost completely, but can't get the massive nut off the main shaft so gave up lol.....

killed another rb20 box in the meantime so rather than rebuilding it i think ill just bite the bullet and go RB25....

      @soviet_merlin Thanks mate!  Nothing too major but will hold me up for a while. I've got lymphomas to get taken off the back of my neck and the middle of my spine which always conjures scary thoughts!  It sounds worse than it is. Yeah great, conjuring more rabbit hole deepening , just what I need! 🤣

      I'd argue the F50 kit I got is very good value. For ~2k I got the calipers (refurbed condition), adapters, pads, brake lines, rotors, and top hats. I think you'd be pretty hard to get Evo/GTR/350z brembos + the additional hardware for similar money. Used market for a pair of front calipers alone I've seen tend to run anywhere from $1500-2000 depending on condition.    That said, something like a GTR or 350z brembo is a lot easier to adapt to the Silvia.

      Is there a significant price difference between the Evo/gtr/350z brembos vs the F50? Looks amazing.

      I was actually being a tightarse at the time LOL... My OCD is tickling me into running a 2nd 8AN Teflon hose all the way down and removing the 2x OEM hardlines. My other side of my brain is telling me to run 2x hardlines front to back (also acts as a fuel cooler, so win win).

      As I mentioned in an earlier post, I had some trouble with the Silvia's brakes dragging back in 2023. I managed to sort it out then, but the same problem came back to bite me late last year. Just take a look at the picture – I had a feeling the handbrake was acting up again, and I was right. Anyway, I'd been wanting to upgrade to bigger brakes for a while. Not that the Silvia's brakes were bad, but it was more of a "want" than a "need", you know? It was funny, though – at the time, I couldn't find any Evo Brembos, 350Z Brembos, or GTR Brembos for a decent price (of course, tons of them popped up online after I already bought my kit!). I ended up going with an F50 Brembo kit, which came with adapters, brake lines, 330mm rotors, and top hats. The F50 Brembo caliper was used in a few other cars too, like the FPV. I also decided this was the perfect opportunity to ditch the Silvia's ridiculous rear brakes and that awful handbrake (some of you were definitely right about that!). I picked up some R33 calipers and all the necessary bits – rear drums, backing plates, and new hardware to refurbish the calipers. Of course, it wouldn't be a project without a few hiccups. Turns out the brake master cylinder was playing up and basically (to put it simply) keeping the brakes engaged. I had it overhauled, and after some adjustments, everything was working again. The whole process took a while, as you can imagine. To top it off, the front right wheel bearings were shot and needed replacing too. This is a rare occasion where I'm posting an update while it's all still fresh! These pictures were taken just this afternoon.
