OGURA flywheel and Ceramic clutch

[rev210]

This is the gear going in on saturday.

The Orurga Racing flywheel. Chromemolly 4.8kgs vs stock cast iron 9.8kgs.

The front of the flywheel. Like swiss cheese.

The Autoclutch , 9 button ceramic clutch plate.

Notice it is using the bonded and rivited discs instead of a staight 'finger' for each button. Allows for more stock like take up, without the chatter.

That flywheel looks wicked.....

I was going to save up for one so i could replace both clutch and flywheel and 1 hit but as soon as i put my front mount in the clutch blew the same day.........hehe needless to say i still have standard cast fwheel :bahaha:

My clutch is glazed for sure. Still has plenty of material left on it but, will never grip the same and probably break appart if given too hard a time.

Did you change your clutch yourself?

I am about to find out how much of a bastard or not the skyline gearbox is to drop out and put back in.

If you did change the clutch are there any bastard located bolts and things to look out for?

[Jay95R33]

Nice..

If you don't mind me asking, how much did the clutch set you back?

What sort of KW are they rated at, and can you run the factory flywheel with that clutch if the factory one is in good nick??

Thanks

No its actually one of the things i didnt attempt.

Got autoclutch to do the dirty work for once i just handed over the cash

The clutch and flywheel look pretty cool. I have a OS Giken twin plate in mine, after the first two days of being close to undriveable the clutch has bedded in and now it's relatively easy to drive.

Let us know how your clutch feels once its in and the difference the flywheel makes. I find with my lighter flywheel that the car will stall really quickly if you don't keep the revs up. But once you move onto a heavy duty clutch there is no going back.

8000rpm launches??

See'ya :burnout:

What type of lightened flywheel have you got?

Your car stalls because of the 'grab' on the clutch, the OS giken is pretty much 'on' or 'off' (the flywheel doesn't help but I doubt this is the major problem). The clutch I'm putting in is very forgiving, I dove my mates gtr with the same clutch, you'd swear it wasn't a ceramic button style.

The 4.8kg ogura is about the lightest around. I'm still going on the install, forgot how much this type of job sucks. Next time I pay someone else to do it.

[GTS-t VSPEC]

The OS Giken Twin Plate comes with a lightened flywheel as part of the package. I agree it is the bite of the clutch which will try and make it stall, but I was told that due to lighter flywheel carrying less momentum when the clutch grabs then it will stop the flywheel much quicker than a standard and hence it is easier to stall.

Don't know if its true but seems plausible.

Well at least you know how to install a clutch, something I would never be game to do.

Good luck with the install.:burnout:

[gtrken]

Ok , I'll bite and completely OT.

What the heck is a GTST V Spec ??

[GTS-t VSPEC]

This is the third time so you'll have excuse me if I copy this from one of my previous posts.

My R33 GTS-t has a VSPEC diff, yes it does have the fins on the diff like the VSPEC's. That means that I have the benefit of both traction control and Active LSD. It came from the factory with this so I presume there aren't too many of them around.

The Active LSD is really cool for high speed cornering, causing the back-end to quickly turn in so you can keep the power down.

See'ya

[gtrken]

Might have the fins but has it got the Hydraulic line going to it from the pump under the RHR 1/4 panel ?

[rev210]

Got the clutch and flywheel fitted up. Now for the gearbox to go back in. arrrg!

Anyone got any tips for putting the gearbox back into the back of the motor. ie: placement/use of jack?

This is always the hardest part.

[Jay95R33]

The boxes on the R33's are heavy, so yeah, use a trolly jack for sure. That way you can move it around easy while it's up in the air.

Try and get the box level and alighed right, then put it in and wiggle the crap out of it.

Sometimes it's easier to jack the front of the motor up so the back of it angles down too.

It is a pain in the backside though. I've never had a box go straight in. You can get alignment tools that are supposed to make life really easy.

The last clutch we did on a R32 GTS4t took about an hour to get the box back in !!! So take your time.

Good luck

Hi gtrken,

Yes it has the hydraulic lines, and also a reservoir in the boot for the fluid for the Active LSD.

See'ya:burnout:

[rev210]

Well the final chapter in the story, title reads " humpty dumpty ".

All the kings horses and men couldn't put the gearbox in again....

Had the mobile mechanic out to give it a go and even he failed. At least I wasn't the only one. Its now in the hands of a workshop with a hoist.

Ya should have called . I have done 3xGTR's by myself on axle stands with a trolley jack. Trick is to angle the engine down by jacking on the front pulley off the swaybar with a scissor jack. Only has to tilt back a little bit but makes all the difference.

That and extreme patience with a flat board bolted to the jack with a custom wedge to hold the box at the correct angle to slip in .

Took me two hrs the first time just to get the box on to the back of the engine without forcing ( can bend the plate very easy , especially if it's solid centre ) but have got better at it now.

Oh well.

Thanks for the offer Ken.

I tried the angle down thing too but I guess without the wedge it was a bit hard.
