flywheel + clutch 6a13 vs 6a13tt

[NLduffyNL]

Ok ive got big problems with my clutch today.
Im pretty sure its broken.
Going to get the gearbox out tonight, then i know whats wrong.
I want to get some info in time so i can build up fast again because the car need to be ready for 1/4mile streetlegal drag @ 29th april.



Ive got the VR2.
6a13TT engine with n/a v6 (6a13) manual transmission FWD gearbox
I had in: The original flywheel and a ACT clutch

Now if the clutch is broken im thinking of replacing the clutch and might want to change the flywheel too. but im not sure what's possible. because ive got the N/A FWD transmissionbox

Ive read some about the evo adapters... If im fitting that adapter could i buy an evo clutch and flywheel then? Or wouldn't that fit to the N/A gearbox?

I really hope some of you could help me. Then this bummer would end up with a little upgrade

[Confused]

N/A is a push-type clutch, 225mm.
VR4 is a pull-type clutch, early ones are 225mm, later ones are 240mm.

I would think it is all about the splines on the gearbox input shaft. No idea if you could do it, but I would be tempted to try if the splines match.
What did Andy do? ( @The Vee )

To bad i cant see the vee's project, i got the membership in my scedule, but this problem kind of throws it over But might be a month later


Aw thats to bad.

Well we allmoste got the gearbox out, tomorrow only the mountings and we can lower the gearbox.

What we can see on the outside: a few oil drips on the bottom of the gearbox. And a lot of gearbox oil in it (so thats a good sign)

Then on the outside there is one cut, like if its done with a tool (about a cut of 1 or 2 mm and 1inch long) i can see the clutch true that.

So im very curious what we're going to see tomorrow....
Might be one of the strips that are on the clutch.

I hope the vee can answer me before im going to order some new parts. Would be fcked up if we're fixing it and its going to brake again in a short time.

I got an uprated clutch from Oz. Think the name is RPW? Guy sometimes on here as Mitsiman? Anyway, it was high pressure pressure plate with paddle centre plate and appropriate release bearing. It was a straight fit for the set up we have. I believe it was for an FTO but won't swear to it. On driving it was very fierce. It would take any abuse but juddered like hell on starting off (was warned it may do this). I couldn't live with it though. So what I did was remove the paddle centre plate and replaced with standard centre plate but retained the high pressure cover. This cured all my judder and does (just) hold the 6A13. Serious abuse in 5th and I can get it to slip but not once it's fully engaged. My set up may not be strong enough for what you're doing, but has served me well for daily driving and fairly regular Ring trips. The flywheel I use is N/A V6 bolted straight to the 6A13tt. Never really ventured into the realms of VR4 flywheel clutch etc as I don't think it fits the V6 box (splines etc) but not 100% sure. Pretty sure though that was one of the reasons I never went that route, other than different flywheel, pull type clutch etc.

Sounds like the input shaft bearing and seal have failed

if you want to go for a lightweight flywheel I have one for sale

[NLduffyNL]

Thanks. Im not sure if the vr4 flywHeel would fit a n/a 225mm clutch (that is what i think ive got). The vee is it possible to check for what specific car your clutch is?

[Adam.Findlay]

no vr4 flywheel fits 240mm clutch which would be an upgrade for you

[NLduffyNL]

but then the question what clutch wil fit. The bad thing is i only got 2weeks And has to be Good in 1try (no time to order new parts when it doesnt fit)

Mark, it's over 6 years since I did this! I'm pretty sure it was for an FTO (225). As I say, the factory centre plate (driven plate friction plate, however you know it by) fits as it should. That is a N/A V6 which I believe is 225. There were issues with fitting a VR4 clutch - I'm sure one of them was the spline count on the input shaft - but I really cannot be certain.

[Adam.Findlay]

check the spline count on your gearbox input shaft and then to talk to an exedy dealer as most exedy clutches are just sold on center hub spline count and disc diameter. if you can find a 240mm clutch with the right spline count you can use it with a vr4 pressure plate and flywheel. or possibly you can use an 225 mm evo 4 flywheel and pressureplate with a different clutch disc to give the right spline count

[Subaru ETA]

My post obviously has been over looked. If there is oil under the car you have another issue - your input shaft bearing and seal have failed most likely

[NLduffyNL]

that is what im going to find out in a couple of hours when im done working. Ill read everything over when im home. the vee: do you still have your clutch damper? (square little box a little b4 your secundary clutchcilinder)

[Jesus-Ninja]

OK, I'll chip in too

You may be able to use a clutch for an Evo with your set up, if you get an aftermarket clutch that is designed to convert from pull to push, although of course you wouldn't need to do the conversion bit. As already said, you'll need to be sure that the splines line up. Aside from that, you can use Nick Mann's conversion kit for the fly.

[NLduffyNL]

Ok this is a lot of information for me, Thanks for that!
I hope im understanding it all cause of my language

We just got the gearbox out.
The flywheel has a lot of cracks on it (Phew glad it didnt break)
The pressureplate has 2 fingers broken. These went a couple of times true the gearbox and made a lot of damage (including a little leak/crack)
And the friction plate has no damage.
Release bearing has to be replaced (didnt have damage but its making noise )


We'll in about 2 hours im going to someone that can weld alloy. I'm going to ask if its possible for him to weld my gearbox.


If so: I need a new flywheel
and i need a pressure plate that fits

i cant find converters from push to pull (only otherwise) But im not sure if that even would fit the gearbox (225 is stock, 240 is a lot bigger)


Can someone help me with finding a new (if possible lightened) Flywheel
And a new clutch?
i'm searching a lot but im kinda getting crazy of it, seeing so much diffrent things, makes it hard to translate and making sure it will fit.

What i had in my car: clutch ACT MB010X with frictionplate 3000303 and Bearing RB010

The Vee : Did you still have the clutch-damper?

i'll post some pictures of the damage thats done.

I hope you guys can help me with finding what i need.

Hmm, coverplate doesn't look too happy! Where is the rest of the diaphragm?!

[NLduffyNL]

You mean the friction plate? That one looks fine, so didnt make any pictures of that.

Got that half of the gbox case here if you want to change
