I was merely speculating based on the photos, due to the nature of the failure, it looks as though the ring gear has separated from the flywheel. But it certainly looks as though your flywheel is a single solid piece flywheel.

Lol and i was supporting that speculation ;) hehe

I just posted the other info as i feel JB clutches get hammered on here by a select few and it is based on an issue that had more to the story too (So i am told)...

Nismo copper mix twin plate all the way, drives like a factory clutch and know of one holding 475 at the wheels, including massive launches and been in the car for 8 years Also have the added bonus o

did Jim tell you it must be your driving style...

Are you saying the clutch recommended to you is a solid centre and not a sprung clutch? Solid centers are cops to drive and will eat gearboxes just because they are bored and they like the taste

Ah i see now how this thread is.

I believe the problem here in is the fact that op wants to run a unsprung clutch which I highlighted before will much gearboxes. something has to give and if the clutch cant ant the tyres dont, then bye bye driveline

I spoke to jez about it as well who btw doesn't have an issue with unsprung but provided it will hold 450kw id go with sprung centre but will need further discussion with jb although jez said in his opinion solid centers are stronger, anyway I really appreciate everyone's input, australia is a democracy and so is sau and its what makes it great on both counts

34 g Tt you run a jb clutch I hear? Which one if so and how is it?

Scott

Yes, I have the carbotic button clutch as you can see in the link to my build thread, it has the special solid flywheel and the really heavy pressure plate too! Its damn good to drive on the street as you can nearly drive it like a normal clutch once you get used to it, and its been holding up to 360-390kw for over a year and it has not had an easy life....

Jim will run you through the advantage of sprung and unsprung, from memory the main difference was the transfer of driveline noise etc not so much the harshness... Anyway, pick his brains and tell him i said hi! haha

Apparently the difference is mine will explode and destroy everything in a 100 mile radius according to gossip on here :no:

Have a look at the link on the last page and you will see pics mate! :action-smiley-069:

lol...still didnt say how much it was

Dont remember... I think the clutch rebuild was around $1000 or something but then i decided to buy the heavier cover and flywheel so there was more too it! It came with gearbox seal, rear main seal and bearing etc etc so it was the whole deal!

GeeTeeTee. It's mostly first hand accounts not gossip.

And when you come off the clutch hard and everything gets too much for the drive line, I'm tipping you lose traction. Don't you reckon the clutch has a lot more to hold when you have 4 wheels making that traction.

They might be fine in your application, but that doesn't mean they're right for all.

Fair enough, but if you are coming off the clutch hard then its driver error? Wouldnt you be loading it up then slipping it to a degree so you do not smash your driveline? My clutch is actually a 33GTR clutch so it would suit your application anyway, just different driving style.

Jim Berry is quite good in terms of understanding your specific needs and purpose and building the clutch around that to suit! Pretty sure PJ is hooking his up pretty hard!

Lol close enough is good enough to me :P And yes the point is valid.

Yep GTT. Agree with your points too, but on the strip and track it's hard to always do the nice soft engagement ( in the heat of the moment ).

Clutch selection is tuff, I've had singles, twins, triples, carbonic, carbon, puck, button, sprung centre, solid centre, and all have their pros and cons.

Yep and when choosing one you need to pick for your own application not just get a clutch as it says 1000hp rated lol

But it sounds like you are pretty familiar with all kinds which is good, also good to see you mention all have pros and cons, there is always some sacrifice when you start pushing the boundaries of performance products, i say mine is nice to drive but thats not to say it doesnt shit me in Sydney traffic once its hot etc... But for my application its good, once i get some decent tyres and get it down the drags we will see how it holds up with my rookie driving!

Well my clutch is on its way! Jim looked after me alot with price which was good of him , soon as its in I will get it tuned to its potential and head to drags hopefully with no explosions lol. Then fingers crossed I get banned for running sub 11 then no need to worry just cruises and hill climbs etc. I'm thinking if switching back to street tyres instead of semis to make an easier weak point in driveline but will keep u all posted

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.

      Not going to pretend I didn't do a bit of junky work this time around, but mostly due to the fact that some things I am not willing to spend days fixing right now, like wiring. I try to do most things properly the first time around.

      Regardless of neglect or incompetence, fixing either is tedious and annoying. Most of the neglect on my car is definitely rust. I hope I can at least pass inspections later on and they won't fail the car due to slightly corroded hardlines. I was generous with rust converter and wax and it looks ok, most lines in the rear are hard to see properly anyways.  Definitely will test them though to make sure they don't rupture under pressure, in that case the car isn't going anywhere this year.
