New Clutch Finished Options

[jdg371]

I have a 97 ST that badly needs a new clutch set.
I would like something similar to stock, but a something a little bit stronger.
So what kinda of clutch set do you guys have in your ST and how different are they from stock.

i just recently replaced my stock clutch with a centerforce 90% over clutch. it has stocklike pedal feel. centerforce also makes a 30% and a 60%. they can acheive high percent over stock hold from centerfugal weights placed on the pressure plate, they are also made in dual friction. meaning there is two types of friction material on different sides of the clutch plate. My 90% has semimetalic material on one side, and kevlar on the other. also i have read that exedy makes clutches for celica's. didnt researched too hard into them.

another thing to remember when replacing a clutch you will want to replace the rear main seal while you are down there. they only cost a few bucks, and it is worth it. good luck if you are doing it yourself.

Elevindie, is your car an st?

when I bought my clutch all I could find was a ZOOM clutch, but if centerforce or exedy make one for my ST I might get one of those.

As for the ZOOM that I have the pedal feels alot stiffer than stock, and gripped harder too although my stock clutch was already starting to slip at high RPM's

yes my car is a st. go here to get one http://www.autopartswarehouse.com/ppc/cent...terforce+Clutch

that is where i bought mine. and i got a centerforce throwout bearing. also on my 94 st it doesnt have a pilot bearing. but this website says there is one made for it.

well i had a Honda ASC certified technition help me, and well we even had a little trouble. and you will have trouble with the rear tranny mount, my suggestion is to hit it with some PB Blaster catalist, and use an air wrachet to get it. and there is 2 aligning pins in the bell houseing, mine were rusted/corroded, and made it hard for the tranny to fall off of the engine. what type of tranny fluid are you going to use? i used Royal Purple. $10.30 a Qt.

I was looking at the site.. why's the GT clutch cheaper than the ST? I thought it was the other way around...

[jdg371]

Just got my clutch kit, I got the Centerforce stage 1 and a centerforce throw-out bearing. While im down there im going to replace the rear main seal... any other parts I should replace while the tranny is out????

Im going to start working on it this weekend.. suppose to be 65-70 around here...

change the tranny fluid. get the flywheel turned (it is a 2 layer flywheel, let you whoever is doing it know that it is, or else your cluth will NOT work), or you can buy a brand new one.

Turned?

Is that the same thing as getting the flywheel resurfaced?

i have a question...

DOES CENTERFORCE REQUIRE THE FLYWHEEL TO BE RESURFACED BEFORE INSTALLING A NEW CLUTCH?

 Yes! Flywheels Are Subject To Heat, Scoring And Warping During Use, Therefore The Flywheel Should Always Be Properly Resurfaced Or Replaced To Assure Good Clutch Performance. Resurfacing Must Be Performed On A Qualified Flywheel Grinding Machine. Centerforce Does Not Recommend Resurfacing Flywheels On A Lathe Or A Blanchard Grinder. Also, Be Aware That Using A Hand-Held Electric Or Pneumatic Grinder/Sander Or Scuffing The Surface With Sandpaper Does Not Constitute A Properly Resurfaced Flywheel. Refer To Your Factory Service Manual For Specifics On Your Vehicle Regarding Flywheel Resurfacing And Specifications (Flat, Step, Etc.).Some Vehicles Require New Replacement Flywheels Instead Of Resurfacing.

when getting the flywheel resurfaced, should i tell whoever's doing it what specifically needs to be done? You said it's a 2-layer flywheel, right?

or should i just get a new flywheel from Centerforce and not worry about it? but that would cost more...

Im bringing mine to a performance shop, not sure how much their going to cut. but Ill tell them what its going to.. they should have an idea

[Elevindie]

YES you have to resurface the flywheel. i got mine done from a local, and he charged me $50 to do it. I dont think that "2 layer flywheel" is specificly what it is called, but the person will know what you are talking about, when you say it. the reason that it need to be resurfaced is because the pressure plate sits in the lower groove of the flywheel, and ther higher groove is where the clutch disk sits. If it is not machined right, the pressure plate will sit higher, and it will not properly clamp right.

Its done!

Clutch, rear main seal, axle seals, and engine/gear oil changed lol
My celi finally runs again.. only 1 flaw tho.. it sucks

It seems that the starter was dropped or something so it doesnt do what its suppose to unless you tap it.. Hopefully the starter from a 4A engine is identical. Right now we have a long prybar in the car to tap the starter to make it work lol
