anyone with experience with this. i wanna crack the 400whp but i was told that stock clutch will go within a week. anyone have any experience? what would be a safe boost level for the stock clutch

 

Just get a new clutch. JWT or nismo.. Stock clutch won't last long. You are installing a TT and thinking about skimping out on the clutch upgrade... not a good idea...

 

+1... better/cheaper to do it all at once....

 

yup especially if you have to pay someone to either pull the motor OR pull the wastegates down in the car cause you have the greddy kit.


do it now, trust me...

 

JWT clutch/flywheel is a good inexpensive quality combo. I have had it with over 400 whp for nearly 16k now, no problems. I can't even count the trips down the track and dyno time.

Besides it is always cheaper to have it done when the turbos are going on versus when the stock set up goes out.

 

I'm pretty sure my clutch is stock and it has held up for like 14k boosted miles

 

I installed my Greddy TT a few months ago and didnt upgrade the clutch.. I am now regretting it.. I need to install a new one here shortly or I will be taking the bus to work..

 

Best advice is to do the clutch at the same time, as there is no extra labor involved with the process. That said, I ran by stock clutch for 12K miles with TT and 400whp, and it held up ok on the street. I never drag raced it with the stock clutch though...I am pretty sure it would be toast.

 

I am on my stock clutch with 12k boosted. I have a jwt clutch/flywheel in my room right now just waiting for the second my stock clutch starts to go I will be switching up WWish I would have done it when I turbo the damn thing though.

 

After installing my Greddy TT, about a month later i had to call sharif and tow my car to his shop for a new clutch. =/ So you can save some money and do it now!

 

Yea drag racing w/ stock clutch is not a good idea.. Thats how I fubared mine..

 

u just cant shift

 

It's all in how you treat the car. If you drive normally or even somewhat spiritedly, your clutch will be fine but ifyou abuse your car, the clutch will go out within just a few thousand miles.

 

Honestly my stock clutch lasted until about 40k miles total on the car. I was making 380 WHP and 370 ft/lb but as everyone else said the additional labor to do it later is just not worth it. If you are looking for a well priced setup that will hold 400 or more HP I would also recommend the ACT setup. I'm currently running the ACT Street Disc and Stage 1 pressure plate with a JWt flywheel but if I could do it again I would have gone with the ACT Prolite flywheel. It just wasn't available at the time. I've driven a few a setups and the ACT setup is my favorite non-carbon clutch to date. You might consider the ACT 6 puck sprung hub clutch, ACT Stage 1 pressure plate, and ACT Prolite flywheel as the 6 puck unit is as streetable as the Street disc but has additional holding power.

 

Mia,

Always good info from you man I appreciate it...

 

Anytime If you search around I did a long winded write up of my set up compared to a few other cars. It was a rather unique opportunity in which I got to drive my car ACT Street Disc, Stage 1 Pressure Plate (here after PP), and JWT flywheel and back to back drove the following configs:

ACT 6 puck un-sprung hub, ACT Stage 1 PP, ACT Streetlite Flywheel
ACT Street Disc, ACT Stage 1 PP, ACT Prolite flywheel
JWT Clutch and PP, JWT flywheel

I'd dig it up but I'm a bt busy at work. I've since had the opportunity to drive the ACT 6 puck sprung hub with Prolite flywheel and a few other setups. To date I didn't get the performance and drivability/comfort i got driving the ACT 6 puck sprung hub / Prolite flywheel setup from any other non-carbon unit. Not to mention that the 6 puck has plenty of holding power for most ST/TT setups. ACT rates the 6 puck at 597 FT/LB of holding power at the flywheel so mid 400s wheel horsepower will be fine all day long. The sprung 6 puck felt no different then my street disc which only has 517 ft/lb of holding at the flywheel. The Prolite flywheel was the best to drive of the bunch too. I was concerned that it being so light might have some issues with a boosted car but the car I drove with it also had a Turbonetics kit and driving it back to back with my car I was quickly sorry I wasn't able to wait for the Prolite flywheel. It was by far the best unit over the Streetlite and JWT setup I have. Hope that helps.

 

I put 70k miles on my stock clutch/flywheel setup with about 6k miles boosted so far. I've had about 100 1/4 mile passes.... I don't baby my car. But as of now, the car is sitting outside the shop and it's staying there. The clutch is done. I can't give it more than 5% throttle without it slipping. I have a ACT 6puck clutch and Fidanza flywheel sitting here waiting to be installed.

Just upgrade it now so you can save yourself the headache. PM me if you are interested in purchasing a clutch/flywheel setup.

 

Everyone drives different, so it is really hard to say if you will be OK with the stock clutch or not. Just to be safe I would upgrade that way when you go for more power later you will atleast have the clutch/flywheel portion of the equation taken care of

With that said we have out Exedy GTM Spec dual carbon clutches in stock and ready to ship, check the link in my sig for details and PM me if you are interested....

Take care,

It depends on the year as well. Early 2003's had much wider friction plates and I'm not sure if the clamping force is higher or not, all I know is the clutch is stronger. I pulled mine and put it next to a clutch off a 2005 and you can tell a big difference. (I have a picture of it somewhere around here)

Oh, and I ran my stock clutch at 370-400whp for 2+ years hard on the street and at the drag strip/autocross. The only issue I had was sticking to the floor in the mountains but I think that was because I had old fluid and boiled it.

 

well after getting all your feedback and talking to the guy down at the shop i will be getting the jwt clutch/flywheel setup. but now its time for my next thread.
