Twin OS Giken noise

I have my first twin plate clutch and it came with the R32. It is an OS Giken. I have a couple questions.

 

While I have the clutch in, there is some plate noise. It's not terrible, but noticable. It is gone as soon as the clutch starts to engage (in gear or in neutral.) And it is not the throw out bearing. Is this normal?

 

Second, while starting from a full stop, occasionally I get a grinding. Best guess is coming from the trans/diff/clutch area. It is different from gear grind. It does not happen between shifts or in reverse.

If it happens, it does while letting the clutch out. It stops when the clutch is fully engaged and only while in gear. And I can't get it to happen every time. If I'm a bit more aggressive on take off, it doesn't ever happen.

 

Any thoughts?Screenshot_20190502-231257_Chrome.jpeg

The noise is definitely normal. 

The grinding may be normal, hard to say from.your description. the clutches aren't designed to be street friendly as the main design goal, they are made to hold the power.

The rattling of the twin plate is 100% normal. Mine (not OS) does it quite loudly.

I'm not so sure that a grinding is though. Is it possible your putting the car in first while still moving. I know mine hates that.

Nope. It's all the way in gear at a dead stop. Letting the clutch out like a normal human being and it'll grind.
A little more aggressive and it doesn't. My theory/understanding is that the plates engaging slowly and separately causes them to rotate at different speed. That's the grinding. That is until they are fully engaged together.
Either way, drive it like you mean it. [emoji38]

      Are these the Dmax ones you are in reference too? https://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35#description Not a bad idea to get the uni flange ones. I have sent just jap an email too. Will see what they say lmao. Only thing is the Dmax ones are on a big back order. Low key anything will be better then my OEM ones I got as they are sounding like popcorn when I go under load lmao 😂☠️🪦.

      Compatible rear drive shafts R34 N/A?

      By GTSBoy · Posted

      They should do. I have S14 (or something S chassis, anyway) driveshafts in my R32 (because my diff flanges have 3x2). They're the right length. When you go looking for R32/3/4 driveshafts (for turbos), they're all the same thing, so are the same length. So there really shouldn't be any reason why those cheapies from JJ won't also fit an R34. R32/3 NA should also be the same thing. The (3x the price) D-Max ones are uni-fit. They have 5x1 and 3x2 bolt holes and say they cover all the cars. So that would also suggest that they are all the same except for the flanges. And in that case, the flange goes both ways. I'd be buying the D-Max ones if I ever have to replace a shaft. Because that will open up diff options without needing to juggle shafts also. Juggling shafts is gay.

      GReddy Injector Help!

      Yeah with the adaptors they do look like the photo above - just the fitment within the plenum itself and then further with the rail to the intake is questionable - we shall see tomorrow hopefully once I get some replies from Aeroflow, maybe those bosses are the missing piece....

      Should be fine, if you have it sitting too far in, you end up just spraying the walls and have shit idle. You "can" run them like that, however I don't think it's a great idea (also depends on your plenum, might be good to just get the injector bosses first, mock it up and see if you need to get the bottom extension) Ideally your injectors, with the extension should look like this  (Not my photos, just Google)

      Thanks for the replies guys, it's really appreciated.  It seems the kit was supposed to come with those injector bosses but hasn't. Unsure if they'll help as even with the adaptors to make them a 3/4 height injector they still sit too far out so mount the fuel rail?
