Clutch replacement adivce
 
I have lost my clutch while driving 2 times now. The first time it was my clutch fork, the pivot ball punched through the fork. This time (about 7k miles after the first time :spin:) the actual pivot ball broke leaving some of the bolt still in the threads on the transmission.

This is what it looked like the first time from the shift fork opening on top of the transmission.

This is what it looked like this time.

Now I was told that the car had a fidanza LWFW when I got it and the first time I did this job I didnt look at the clutch or flywheel because I was just rushing to get the job done. This time I removed the clutch and found excessive glazing on the flywheel and the clutch has about 30-40% life left so I'm going to go ahead and replace it. The flywheel that is actually in it is a F1 racing flywheel so I believe I can only run 06+ wrx clutch on it and have to get the flywheel refinished instead of just replacing a plate.

I'm going to reinforce the crap out of the fork and powder coat it, attempt to remove the bolt still in the transmission from the pivot ball (any adivice on how?) and install one of the transmission input shaft sleeve things. I need some advice on a good clutch that can handle power and is cheaper than an act.

I was in the middle of a stage 2 tune with infamous so it needs to handle that much torque or more because I'm planning on getting a 20g down the road. the clutch that is on it is an exedy stage one and I have read some people saying it cant handle a whole lot of extra torque so I dont know if I want to go back to another one of those.

Any advice would be awesome.

power upgrades: AVO TMIC, STI UP, cobb catted DP and a borla CBE

If you can't drill and use a easy-out to get the threads out, you may have to have a machine shop remove it.

Any time you replace the clutch, you should resurface the FW.

Yes, the TSK3 kit is one thing you should have.

I wouldn't bother powder coating the those.

contact m sprank or Mike at AZPinstalls.com and see what he recommends for a clutch set up.

So you're saying you need something that can handle a 20G and I'm assuming with supporting mods.

As far as the Exedy not holding up, check this thread out:

http://legacygt.com/forums/showthrea...it-151475.html

It's rated low, but LALGT has a high power setup and it's holding up fine. Of course, it depends on how you drive it too.

Maybe look into the Spec options.... You'll need to check the torque ratings on those though. http://www.fredbeansparts.com/spec-s...tch-kit-s.html

Pretty sure LALGT has a Comp Clutch stg 3.5 setup now. They're killer for the price point. I have the same one in my car and love it so far. Had to send my ACT HD setup in for warranty work and couldn't afford the downtime while ACT inspected/warrantied my setup.

To the OP, if you like ACT, I will be getting my HD setup back from them this week. Brand new pressure plate, refaced clutch disc, resurfaced streetlight flywheel. Will be posting FS once it gets back to me. There's another member who has the PP and clutch disc FS currently as well. GL with your decision!

Yfarmeaahka 10-08-2012 10:44 AM

Thanks for the advice guys, I notice on the exedy stage one it was warn more on the outer edge of the disc than the inner and I'm not sure how that would happen. I would like to get an act hd clutch but man they are steep in price. Ill check out the spec options and look at the torque ratings. I'm honestly not sure how much torque the setup I'm planning on going to will have. I noticed a lot of people have the ACT HD clutch so I'm assuming its a pretty smooth and strong clutch.

I am planning on getting injectors and a 20g and possibly trying the tgv delete, seems pretty easy just a lot of grinding. I have an STI fuel pump at the moment and I'm not sure if thats enough or not.

The part I'm most scared about is getting this freaking bolt out. I have a reverse threaded drill bit and a bit that grabs the broken stud once its tapped so I've got my fingers crossed that its going to just come right out.

As max said, the bolt may have to be extracted by a machine shop.

As for clutch and flywheel, with the power you plan to have I would go with an ACT HD combined with a lwfw. Definitely don't skimp on the clutch if you plan to go with more power down the road. The TSK3 is also a very good item to use as well.

The ACT HD is rated to about 420 ft-lbs at the crank, which translates to about 336 ft-lbs at the wheels. I think a Stage 2 setup yield somewhere in the area of 240-275 ft-lbs, depending on the dyno... at least that's what I got from searching a bit.

Here's a bit of a comparison for reference:
http://legacygt.com/forums/showthrea...d-140671.html?

According to that, a 20G will put you just over the limit of the ACT if you're running E85. Also, I would expect that it can probably still hold up fine if you don't abuse it and especially on 91/93 instead of E85. But personally, I'd get something that holds more torque if I were going with a 20G only because I like having an extra margin of safety.

It lasted only ~15k miles at my power set up BUT IT DID HOLD!!! The FW was blued and the clutch was scorched. The TOB was a MESS. Between the driveability issues and the fact that there are other clutches with a much better pedal and engagement feel that have higher holding capacity sells me on everything else. I will never, ever run an Exedy staged clutch in any car I have when there are better products out there.

Yeah, that exedy stage1 only held up for so long.

iNVAR 10-08-2012 11:11 AM

Ah, well, there you go, there's the answer from the man himself haha. :)

Yfarmeaahka 10-08-2012 11:19 AM

Well alright haha. I hated the way my exedy felt but it was put on the car around 80k and I got the car at 113k miles so there is no telling how the car was driven before I got it. I knew how to drive a manual before but had never owned a manual before this car so I pretty much learned how to properly drive manual on this car so I know I haven't been nice to it. I have driven a 350z that had some ridiculous race clutch and I hated it. It was engaged or disengaged, no in between and it was terrible. So I want something that's going to not be too ridiculous for daily driving but can handle the stage 3 20g that will be on 93 gas not e85.

Was it a stage 1 or stage 1 hd?

I would need an 06+ wrx clutch for the F1 racing flywheel not the legacy clutch right? And does anyone have any experience with the act 6 puck?

Max Capacity 10-08-2012 02:20 PM

6 puck, can you say on/off switch. But that was was a un-sprung disc.

I think the Spec 2+ may be good for goals, check them out. Mike from AZP can help you with that.

PM or email him, he'll take good care of you. He's take great care of me.
I also beleive the 06 -07 wrx FW is the same as the 07-09 Legacy gt's.

They also fit into the 05-06 GT's.

I looked at that but it's only good for 370ftlb where the act is 420. I'm not sure if 370crank tq would be enough for a stage 3.

Yfarmeaahka 10-08-2012 03:53 PM

Mike what are your thoughts on a spec 2+ clutch vs act hd on a stage 3 setup?
