What clutch are the turbo people running?
 

If I ever go FI down the road, I would definitely upgrade the clutch/flywheel setup.

On my old turbo G35, I ran an ACT 6-puck clutch and Fidanza flywheel. Granted the car made under 400wtq, the clutch NEVER slipped for the 50k miles it was boosted.

I'm curious to know what all you turbo guys/gals (wishful thinking) are running for clutch setups? I've seen a lot builds with the OS Giken, but I think that's a bit overkill.

Unfortunately not much clutch choices that would hold the torque and be nice enough to be daily driven... i've tried them all on my old z33 TT.

We literally just tried to see if we can do TT installs without a clutch in the beginning, on Nigel's car. didnt do too well, lol Lasted about 150miles on it.

With clutches, you get what you pay for... even with the abuse that I put my old Z33 through, was making about 474rwhp and 47x tq, the Giken twin disc was perfectly fine. plus i drove from nassau county to work in suffolk county then to the upper west side of manhattan EVERYDAY, in traffic!

if i get bold enough, i'd take a pic of my left and right legs, they're still proportional ;) the engagement and pedal feel was slightly stiffer than stock but not overkill like a 6 puck would be

I ordered a Southbend DXD Stage 4 with new flywheel along with an HD CSC kit. I don't now much about this stuff, but my car will be a daily driven boosted car pushing around 420-470 whp.

which HD CSC did you order?

I will be running the JWT clutch/flywheel combo with the concept Z heavy duty CSC. My install should be getting done the first or second week of April, so I'll let you know how the setup feels.

HD CSC ordered from ZSpeed. I wonder if Concept Z is selling the same product. It comes prefitted with ss lines, so there is no need to purchase a clutch line upgrade.

This is the one I have:

I have a southbend stage 4 and it feels great and is supposedly good for 600+wtq

Also, its easy on the CSC. I've had a factory CSC in there for several thousand boosted miles already and no problems.

I have stock clutch and flywheel with over 2k boosted miles.. and holding strong

Jdm. Are you saying the os giken was good? Sorry, but your post confused me a bit.

Just to let everyone know, I purchased an ACT 6puck clutch and Fidanza 15lb flywheel.

We like to use ACT 6 pucks also!

Have you installed any on a 370z/g37? I'm curious how the stock CSC has held up.

Still Running Stock Clutch ;)

same here stock clutch ftmfw I paid for it so I am going to burn it up lol

I'm glad to see that people are having good luck with the stock clutch.

I'm with toner. I'll be running the stock one until I need to change it.

I find it strange that you guys are having luck with the stock clutch. My car has only 3500 miles on it and has been boosted since 3000 and it slips. I can get a couple of pulls out of it thats it.

Now if I baby it the clutch doesnt have a problem I am getting rid of it soon.

for sure you are!

better be there on monday to get that thing.

i agree with squeeze... so far every car that we've boosted needed a clutch prior or during steady state tuning. stock clutches are already slipping during tuning on the dyno, i'm amazed that some of you are holding up.

i wanted to verify it on nigel's car, so when his car had the TT kit installed, I instructed my tech to not install the Giken clutch to see if how long his stocker can hold up for. lets just say it didnt make it past tuning. Granted he could still drive on it while babying it on the streets, but if you laid on the gas pedal and did some spirited driving, it was slipping.

I will be home for sure I am not going to miss the UPS man lol .

Yeah, the stocker is horrible for launching. I think for simple daily driving you might get better longevity out. But for spirited use, we like the OS Giken Twin Plate. It's the last clutch you'll buy for the VQ37.

I don't have any experience with OS Giken on the Z, but it was the truth on my (Euro CA18DET) S13 Fastback. If it is anything like the one I had on the Z, then it will be the money in traffic or during high performance driving.

thats exactly my experience with it. I DAILY drove my car 120miles a day in nyc traffic for a long time till I got rid of the car. you get what you pay for

I'm about to suck it up and order an OS Giken. My Fidanza flywheel is sittin in t garage that I've just read of it failin on RCZ's car and a few others and it's been 3 weeks since I've ordered my ACT 6puck and I dont even have a shipping update. Grr

i have tried different clutches on a lot of cars , both import and domestic , and i never seen a better clutch feel than this one , but the car is almost new so i didnt drive it much , but i cant tell u this , it holds up more than fine for daily driving and insane driving
this combo is the best so u can be headache free for atleast 100kmiles
- Southbend Clutch STG 3
- ZSpeed Performance Heavy Duty Concentric Slave Cylinder w/ stainless steel lines

My Z isn't boosted but the stock clutch has taken plenty of abuse launching. ~100 track launches and half of them were @4,000 rpm. (knock on wood)

When I had it taken out it was still usable (no slipping), I put in a new OEM clutch for good measure (installed lightweight flywheel). no complaints from me on the stock clutch.

How necessary is a new CSC? I am looking at an OS Giken Twin plate and thinking I need a new CSC as well...

I thinki depends on how you drive. If you are getting a new clutch might as well throw one of those bad boys in there while the trans is droped. If you plan on upping the boost right away I think a new clutch is a must. I have been at 6.5psi for a long time so my oem gear works just fine. Might as well have some fun with the oem clutch before getting a new. :happydance:

The OSGiken clutch is one of the hardest on the CSC. It will blow your stock one quickly so just go with the upgraded one right away...

We supply Concept with our slave kits ;)

Running OS Giken Twin Plate for over 10k miles. No problem with these and absolutely no slip.

Are you running the stock CSC or an upgraded one?

Also running the os giken but had the csc replaced to prevent any issues. How are you guys launching with this clutch it grabs hard and stutters if i dont treat the stop light like a xmas tree, I feel like a 16 yr old learning how to shift a manual again :/

Aaaaand my stock csc died a few weeks after posting this. My advice, buy the metal csc, might as well install it while youre in there. Will save you money in the long run.

:iagree: If you are in there get rid of the factory piece of crap.

I'm NA and my stock clutch slips on the 1-2 shift with V710's mounted.

Just got my own OS Gkien Grant Touring Twin Disc... anxiously waiting to get some time to put it in with our own custom CSC.

Anyone have a link to buy the CSC upgrade for a OS twin clutch? I will buy it right now.

350z 370z heavy duty CSC Concentic clutch slave cylinder

just specify the os giken as its more expensive

why is there a osg specific version??

I won't go into much detail about this as obviously from the post in here others are making there own CSC versions.

There are areas that need addressed just for the OS giken clutches, get this wrong and the slave will not last long at all if it makes out of the garage before it blows out.

Over the last 2 years of testing with many different clutch set-ups we have all the bugs worked out and have an amazing product!

We have many, many customers in our Zspeed HD CSC with Zero failures. We actually have one customer that has been through 2 OS giken twin disk rebuilds on the same slave kit, he does nothing but drifting and beats the living **** out of it :tup: Says a lot for its durability.
