Project 91 "SS" 3400/5spd

[MY91GT(Z)]

damn they are expensive and whats the difference between the + and the reg one

[woody90gtz]

The 3+ is full face, so it doesn't chatter like the 6-puck stg3. And it holds more power and supposedly lasts longer.

The 3+ in my Camaro is rated for 800lbft and the streetability is still really good. You can slip it if you have to, but it held when the rear end didnt with a clutch dump on drag radials at the track.

Well, this is sad that this thread hasn't been updated in almost 5 months!

I did buy Robert's old SPEC for cheap, should be here this week. Hopefully before Feb is over I'll be tearing in to it.

I miss my clutch cars.

I was wondering when the last time you was in here...

What all do you have left or plan to do to it this year?

Haha really cheap,i just hope it helps you with getting it back together.You got a free T-shirt in the deal too!!!Haha

I've got to replace my slipping clutch, and I have a rear disc swap to do and KYB struts to install. Been working on the damn house all winter so far...

[Robert 89gt]

I would do a rear main too just for piece of mind.

[woody90gtz]

Well, yeah. I'll find out what caused the clutch slip once I get in there. I was going to do some custom AN hydraulic lines too, now that I think about it.

[MY91GT(Z)]

i almost bought that clutch but wasnt sure if i should or not but ill be ordering my new clutch next wk and ill be tearing into my car by the end of the month for the clutch, brake and suspension work at once and then i have something else on the way for my motor

where did your get the adaptors for the rear disc swap i want to do this at the same time and if you cant get xtra set made im willing to pay

[woody90gtz]

I'm machining them myself, and it's a pain in the dick with our ancient mill at work. I got the brackets from alpinestar on v6z24. He actually just made an account here too.

[DTMAce]

Sounds like you have your work "cut out" for you... lol

[woody90gtz]

With the nice warm weekend I decided to tear into it finally. I had to sacrafice an FE7 endlink that just would not come apart...so I'll be upgrading to heim joints sooner than I had planned. haha Not a big deal though since I need to convert to the different FE7 bracket for my new KYB struts anyway... And that god damn driver axle still would not come out (attempt #4 since 5-09), so I'm thinking I might split the trans again to release it from the diff. Jeff machines the spiders in the LSD conversion process and it takes out the rounded part of the splines for the spring clip to pop out of. Royal PITA.

As for the clutch... I don't see any trace of oil on any of the friction surfaces or anything. The flywheel & pressure plate show some heat, but I think they are salvageable. The disc is fucked. The friction material started tearing and there's friction dust caked on it. I don't know if the stock clutch hydraulic restriction was the culprit, or if a SPEC clutch just doesn't hold what is advertised...but it was slipping pretty bad obviously.

I compared my SPEC stage 2 to the SPEC stage 2 Robert sent me and they're quite different. It is a stage 2, right Robert? One side of the disc is similar, but the other side of the disc and the pressure plate are both different. The thicknesses of both are also different, but that was expected. I will measure both discs tomorrow and give SPEC a call, hopefully I can use Robert's disc with my pressure plate.

It was a beautiful thing doing this project in MY garage with MY tools where I put them! The organization saved a lot of time compared to working in my dad's garage where it's hard to find anything.

Enough rambling...you know I'm a pic whore!

[woody90gtz]

Bellhousing had some very light oil on it (not sure where it's coming from) but the clutch itself had to oil anywhere...not even a mist.








The disc looks oily but it's just friction dust I'm pretty sure. The flywheel has zero oil on it at all, so it can't just come from nowhere.

Clutch comparison: mine and Robert's.

Why re-use your pressure plate? Will the one Robert sent not work?


Oh and Spec FAIL on that one... Damn I think this is like the second clutch fail thread of yours now(granted only one being your mistake)... So hows that 5-speed swap treating you

I wonder if Spec sent you the wrong pressure plate after you killed your first one, and it was a miss match with the disc they originally sent you... Either way the fact that none of those parts look the same is one reason why I would switch to someone else if you do infact have two Stage 2 clutches right there.

As far as your axle clip issue too... Probably one of the bigger problems is the fact that your using completely aftermarket axles and the c-clips on those axle are not shaped the same as factory... The ones I got on my 100% new axles that I used were a very square edged clip, so there was no way in hell they would ever collapse... The OEM ones are squeezed a little bit tighter and they also have a rounded edge to them to help them compress when being pulled. I have to fix my intermediate shaft this year because I think the groove is cut too deep in it which causes the clip to get all out of position and make it harder than it should be to get that out.
