My good friend just aquired a 91 nsx with a couple little defects...one happnes to be that the clutch seems to be slipping shifting over 4k rpm (I haven't yet gotten to drive the car but this is the impression he gives me). He has been looking into replacing it and came at me with a $1300 estimate. Now is this true? I mean if the clutch is done in an nsx would it usually cost this much? I'm just in disbelief because my gsr cost 350 for the whole assembly from ACT. I know my car is WAY more mass produced, but common....$1300 was the best he could come up with? TIA

 

Yes indeed, they can cost that much and that's just for the clutch alone w/o labor. Science of Speed has some new clutches that your friend may be interested in that are quite reasonable. Or you can go with Dali's carbon clutch for 4K.

 

geesh, well one of a kind car, one of a kind parts huh? Also he was making some comment on how they were twin disk...does it come with a twin disk stock?

 

Yes, it does. Though you don't have to keep it w/ an aftermarket part. I'd suggest keeping it though.

$1300 is about right for a stock clutch. (And the aftermarket clutches vary in quality.) Throw in another $800 or so for labor. (Doing an NSX clutch job is a major challenge for even the most experienced do-it-yourselfer.)

The twin-disc clutch is only on the '91-96 NSX. In '97 they changed to a single-disc clutch. It costs about twice as much as the twin-disc clutch.

The NSX is not a GS-R. Not even close.

If your friend lives in the San Francisco Bay area, he might try getting an estimate from Don's Hilltop, which is an independent shop just south of the city that is highly regarded for their NSX service.

 

well I'm going to do the work with a friend of mine, I've done tansmission work on old and new cars, what exactly do you mean a major challenge? Have you done one? Do you know what the challenge is? Just wondering if I need to pick up any specific tools...

 

You'll find out.

I hope you at least have the service manual...

 

What could be so different, easy on a rwd car, diconnect driveshaft take out tranny bolts and drop the tranny to expose the clutch...

And I told him to pick up a helms.

Go ahead, try it - and then report back to us on how easy it was. If you post a good write-up, it can be included in the DIY section of the NSX FAQ.

Keep in mind that it takes an experienced NSX tech (one who has done this numerous times) anywhere from 8 to 12 hours to do. And that inexperienced NSX techs often get the initialization procedure wrong.

 

Wellme and my crew are gonna try and we'll take pleanty of pics and notes and do a write-up, just like the sr20 swap in the tech section, I'm really curious to know what the deal is...hmm maybe you have to drop the rear axle like in an mr2...you're scaring me man hehe

 

Make sure you pull out the throw-out bearing fork before you try to remove the tranny.

Also you will need a clutch alignment tool. I borrowed one from the local Acura dealer. If you cant you will need to buy one. It comes in two pieces that need to be purchased seperately.

DO NOT SEPERATE THE BALL JOINTS. AND BY NO MEANS USE A PICKLE FORK!!!!
My local dealer told me he just got done replacing $3k worth of parts from some idiot that tried this.

*edit* fixed wording

You have to romove the fork before you take off the tranny?, this IS going to be different then other rwd cars...and I have a couple clutch alignment tools from the ACT clutch's I've installed in the past, thanks for the heads up

Glad you saw what I meant, yes you have to remove the fork before you pull the tranny off otherwise the transmission will not come off.

I might try a generic alignment tool on a single disc clutch but I will be surprised if you find one that works on the NSX. Best of luck!

 

throw out bearing

I work next to a guy that does them in about 4-5 hours. He has done a few. It would probably take me at least 8 hours to do my first one. I can do Integra clutches in about an hour if I hurry. Let us know how it goes for you (Terrible One). BTW, everything for the NSX is twice as much as other Acura models.

 

Go with a CC or a Tilton.

They can't be beat for performance.
