Question 02 WRX need new clutch, need advice

Hi all first off i would like to say i have ready the stickies (I am a newbie), i have also spent hours doing research and searches on many forums (mostly this one).

I need some advice.

I have 2002 WRX. Only mod is a short throw shifter with no bushings.

Waiting to get installed parts: Injen Intake, Turbo XS-RFL BOV, Turbo XS dual stage boost controller

I am also looking to purchase a ECU and an exhaust system and get everything installed at the same time.

Now thats background on what I want to do.
__________________________________________________ _________________________________________________
Here is my question:

The clutch is going and I dont know if I should go with a stock from dealer(Quoted $1300 with parts and labor, not sure what parts or what labor)

I was looking at aftermarket. I dont see my self doing a lot of power mods in the near future the car has 91K miles. I do want to keep it for ever(or as close to it i gues, love the car)

So my question is do i go with stock, or aftermarket. If aftermarket what is good brand and do i need to repalce the flywheel. Also since i do want to keep the car for a long while do I do any other tranny mods since it is apart either way.

i have a mechanic friend that is going to do the labor in his shop so i am sure i can get him to do other work with out charging too much.


I was looking into the ACT SB3-HDG6 Clucth Kit and 600175 StreetLite flywheel. Is this a good combination, any other Brands that may be better?

What else shoudl I replace while in there, i ready that tranny mounts are a nice addition

ANy and all help will be appreciated.

ditch the Injen Intake(smaller than stock diameter tubing), Turbo XS-RFL BOV(useless), Turbo XS dual stage boost controller(up to you but you should just get some sort of engine management.

you will be very happy with exhaust+tune.

stick with the stock clutch which can be bought for ~200 bucks and resurface your stock flywheel. You don't need the act clutch, and the lightweight flywheel will only give you problems such as noise if everything is not balanced, or CELS. The stock clutch will be able to hold more power than you will make even after mods.

buy a stock clutch kit online for 200-220 and get your mechanic friend to install it for you and resurface your stock flywheel for cheap(compared to dealer quotes).

but I doubt you will listen and you will end up installing that intake, bov, and heavyduty clutch and lightflywheel that you don't need.

ps. and more research never hurt anyone

I have an 02 that I bought new and I am using an Exedy stok style clutch, which is definitely an up-grade over stock, I LOVE my ACT streetlite flywheel (no CEL, ever), the injen intake is the one I wish I had. As far as the BOV, they sound cool but I don't care for the other effects. I us use a TXS HPBC and am faster than Cobb stage 2 W's and stock STI's. I autocross and 1/8 drag my car , am a master certified tech. My car has 102k miles with no EM, no fuel upgrades, and 17psi. Been running this way since 30k so don't want to hear any "think of longevity" crap! It doesn't take thousands of dollars to have a fast and fun WRX.

Well just as i figured, everybody will have different advice.

Well im still reasearching but getting good advice and input for all.

I think i want to be under 300 whp, when i am done so i need the clutch to handel that i know stock will work but aftermarket will be cheaper even if i add a fly wheel.

So besides noise during downshifting what is the loss of top end vs the gain of excelaration? Who really goes 140mph anyways. I havent gone over 90mph in over 4 years.

So is a stock clutch still the way to go and a stock flywheel?

Stock clutch, don't replace flywheel unless it is damaged (look at it when you get to it, any mechanic will know). Get the clutch from Ebay...seller gripforce clutches...WRX Exedy OEM clutch around $200.

DO NOT put that INTAKE OR BOV ON YOUR CAR. You say you've done research and read the stickies/FAQ's? Those are the FIRST TWO THINGS you would have learned NOT to do if you really had read. Now go back and READ THE FAQ's.

As far as the boost controller, they work on 02's, but exhaust and EM are by FAR the best choice for someone who doesn't know very much about how to set boost levels and/or monitor those levels.

CN: get stock clutch, resurface flywheel if necessary, ditch intake, BOV, and boost controller, get exhaust and EM, and enjoy your car.

Resurface the flywheel and go with either the stock Exedy replacement or the stage 1 Exedy. With your mods, a stocker should be just fine.

Instead of buying a BOV, Intake, and MBC, just get a reflash. You will end up with WAY more power and your car will run WAY safer and smoother.

As far as the clutch goes, go with the Exedy Sport clutch. It feels great and grips a lot better than stock, as well as being identical to the OE clutch in fit and quality. It will come with a new pilot bearing and release bearing... You should replace them both, IMHO.

It's also a good idea to resurface the flywheel, but since you're taking it apart, spend the extra couple hundred on a new light flywheel. Don't go ultralight (like the Fidanza)... Go moderate like the Exedy or ACT Streetlight...

So lets say I don't have a budget (on the clutch and flywheel), and i want to make sure I don't have any or as little as possible problems.

From what i can tell is, everybody is saying I don't need a Stage 2 or a Race type clutch and no lightweight flywheel.

Taking into consideration I want to make close to 300whp in the near future, should I still go with an OEM clutch?

Id rather not take chances by cutting the flywheel (also what my mechanic friend said) and just replace it even if with an OEM one.


So is an Exedy stock replacement better than an OEM Subaru clutch? And if so is the ACT Heavy Duty as good as the Exedy?


JonR - I purchased those parts 3 years ago thinking i can use them and i had the BOV and intake on the car and I am pretty sure its what caused my CAT
to over heat and in turn blow the turbo by spitting crap into it. The dealer replaced the turbo under warranty and when i asked what could have caused it they said just a defect.

The boost controller was purchased for me for XMass. I had dreams before now I just want the car to go a little faster and last another 200K miles. The exhaust will need replacing soon so thats when I will get a better one and add an EMS.

mckenzietj - Want the intake? Had it on the car for like 6 months maybe, now its in the shed. Sell it to you for $30 plus shipping (or pick up).

Default Go with the light wieght flywheel

I had the same questions when I went to replace the clutch in my '02. I finally decided on the Exedy with the ACT Streelight. It's worth the switch, unless you drag. Otherwise, shedding those extra pounds off the flywheel will free up more power to drive the wheels.

I'm with the rest of the crew on the Injen, bov and the like...more show parts than go. But if that's what you're into, knock yourself out!

Yes, you should still go with a stock clutch with 300WHP. You want your clutch to slip before your transmission blows. Taking a chance with a stronger clutch is taking a chance with your transmission. Until you have the money to replace your tranny with a PPG gearset, don't get a stronger clutch. My .02
