After my last track day my clutch is slipping so bad I can't rev over 3k rpm without losing all power to the wheels. Which isn't great timing considering the private track day we have in a couple of weeks.

Was going to get a Exedy HD Organic kit (part NSK-7172 SC) to replace my stocko but I'm having some trouble finding a reputable installer.

So far just for the part I have been quoted from ~$800 up to $1650! Installation pricing has been likewise BS >.<

Anyway I need some advice on an installer. If anyone has any advice it would be greatly appreciated, PM if the reponse is going to violate forum rules obviously.

I dont mind travelling anywhere in Adelaide if the job is done right.

consider this...we can do a GTR clutch and flywheel replacement in under 2hrs. (1hr50mins) and i dont work on cars for my day job.

anyone who quotes more than double this in regard to labour is blatantly ripping you off or has no idea what they are doing/how to do it.

How much power are you making, or planning to make?

If it's anymore than 250kw in a GTR i'd move away from organic clutches (personal preferance)

Have you rang Adelaide Clutch Service (or what every thay have changed their name to now), they are the manufacturer of the Xtreme Brand Clutches and they are in Adelaide.

i can recommend

Kent Brake and Clutch had done 2x installs for me charged me around the $400 mark and i supplied my own clutch from Xtreme to which i possibly wouldn't buy again

Adelaide Radial Tyre look after us will charge around $350-$400 labour there is more for machining of flywheel

Boostworx will charge around the $450 mark and that includes a flywheel machined

obviously all these prices are labour only

and as Dale has said i would move away from the organic and get a 5-6 puk cushioned ceramic

for more information about NPC clutches that i was doing group buys for >>See Here<<

Talk to Kudos Motorsport (in the traders section) He will sort out a Genuine Exedy unit for you at a great price (cheaper and better than an extreme, and not a mix and match kit like so many others out there which fail very quickly), I got mine delivered in 3 days. GTR clutch and light weight flywheel cost me just over $1000 delivered.

As for installation, if you're north try Rhemac Motors in Gawler, talk to John. Since they are a machine shop (the best in SA) they can skim your flywheel in house and possibly save you a bit of time/money. They fitted mine, plus s.p.i.g.o.t bush for under $400(don't quote me on that)

Give these guys a call http://www.directclutchservices.com.au/index.htm they're building me a clutch atm and it is built to suit my power and driving style. It was also the cheapest twin plate i could find. If you look at their web site you'll see that a fair few drag racers use them and so did last years Drift Australia winner.

Or buy this as it will suit your car http://www.skylinesaustralia.com/forums/Rb...G-t281075.html# If i had a pull type clutch i would have brought it.

Wow. Awesome advice.

2 hours you say? Hmm I was advised 5 by my usual workshop...

280awkw currently. I thought organic as its my daily and didnt want something too "grabby" in heavy traffic. I would like to occasionally dump it from high revs but is really not essential. I tractor round Mallala about once a month so it does need to handle that.

I looked at Xtreme as the other options, didnt realise it was made in Aus which I would prefer. Why wouldn't you go Xtreme again Steve?

Nice price on the twin plate exedy, would be great to race with.

There is some work to do tomorrow I think :D

i think my money could be better spent else where nothing wrong with the 2 extreme's i've had so far just might of been over priced paying for the name type thing

ive had ceramic clutch in my car for the past 4 years and wouldn't go back to organic its very easy to drive not too grabby doesnt drive atm so cant really show you we'll could chuck a battery in the ol girl and drive it 10 meters up the driveway :D

My mate Chris and myself have been doing a few clutch changes this month. Dan (Inline 6), Chad (Dstroy) is in the progress atm.

Takes us a couple of hours as we dont have a gbox stand yet so a wheelie bin and 2 15's fix that.

We do have a hoist tho with a huge amount of tools.

I've got an old extreme in my shed that has been fried, was in a 200kw car and daily driven. Didn't even do any big launches as it was crap and would slip even from new. I only tried it once and realised it was never going to happen.

My R32 has a said clutch, and quite often it sounds like mechanical armageddon when selecting 1st gear, and subsequent gearchanges when under load ie. hills driving.

Went from thrashed OEM to xtreme in my last car, NEVER AGAIN. Engagement always felt spongey, only dropped the clutch twice after that wheel spin attempts were fail, wouldn't snap shift, launches always sucked and the overall feel was terrible, ruined what used to be a good daily driver.

funny, my xtreme clutch works beautifully. hasnt slipped, has never sounded like 'mechanical armageddon', never felt spongey, never had trouble snap shifting with it. and im not exactly easy on my clutches, i have very little mechanical sympathy for them.

Hi Chad, interesting pic, idle curiosity, was wondering how long this clutch was in service, rated transmitted hp & did you get any feedback from the manufacturer on this failure? I was thinking it looks a bit like a metalurgical problem (manuf defect, either temper or selection of base plate thickness ~ I've seen a few mis-matches in other power transmission applications over the years but not an expert) or mis-matched power rating?

My 2c

Cheers GW

I use Nismo twin plate sc, never been hammered.......yet.

The clutch was installed in about 2006 when my car had a little old RB20, It's an extra heavy duty single plate, not sure on its power rating. My car now has a RB26 making 324rwkw and has seen about 5 track days. Since the power increase i have gone very easy on the clutch. I haven't spoken to the manufacturer about it as im pretty happy it lasted as long as it did.

Had a new Exergy HD clutch fitted todayby Sinergy motorsport, looks like they did a good job. Where most other workshops couldnt accomodate me at such short notice they had the part shipped and installed within 3 days, only left my car at the shop for a few hours. Price for install was the nicer side of $400 as other posts had suggested it should be.

Cheers Kim for the recomendation, and to everyone else that posted - I really appreciate the help.

Only stalled it 4 times on the way home too :happy:

    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
    • hahah when youtube subscribers are faster than my updates here. Yes some vid from the day is up, here:  Note that as with all track day videos it is boring watching after the bloopers at the start.  The off was a genuine surprise to me, I've literally done a thousand laps around the place and I've never had instability there; basically it rolled into oversteer, slipped, gripped and spat me out. On the way off I mowed down one of the instructor's cones and it sat there all day looking at me with accusing cone eyes as I drove past. 1:13:20 was my fastest lap, and it was in the second session, 3rd lap.  It (or me!) got slower throughout the day as it got hotter.      
    • It sounds like you want what the Toyota Landcruisers have for their roof racks. Wanna know what you end up with? Rust holes in the roof, and water everywhere...
    • Discovered today that if I select reverse first and take my foot off the brake, then select drive, the drive indicator light works and so does the tiptronic gear indicator. 
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Does anyone here have any ideas?   Cheers guys
