Replaced my clutch and flywheel and brakes today in about 8 hours mostly on my own and taking it quite easy. Had a mate working on his Audi next to me so we'd lend each other a hand when needed (eg lining up gearboxes 20 minute job).

These flywheels are an abbomination.
If any Gen3 owners are having troubles with their Dual Mass Flywheels the easiest and cheapest way to replace them is to get an EJ22 flywheel and clutch kit.
I've just spent the day replacing mine and the difference is fantastic. Much lighter to use and takeup is more gradual.
Don't ever replace with another Dual Mass setup.
I didn't have time to take any pictures to show the differences between the setups sorry but the DM Flywheel is just that, a 2 layer flywheel that also allows gradual take up of the pressure and clutch plates. Really, really pointless.

It's all good. Just consider work as the necessary evil to get you back to QLD.
How's the car going?
I'm getting good at this clutch change business, luckily a mate lent us his workshop so jobs are easy with the right tools.

Did you use the ej22 clutch aswell? Because gen1 and 2 are a cable clutch (pull method) which uses a different pressure plate and spigot bearing to what the hydrullic (push method) system uses. Thanks for giving a bit of detail about the dual mass flywheel, I was trying to explain it to dad but it was a bit hard when you don't know what it does lol.

I used the EJ22 flywheel, pressure plate and clutch plate.
All NA Subi's are push action be that either cable or hydraulic. Turbo boxes are pull action and require a different technique for removal.

Thanks for that Frank.
Our GenIII RX has the "flywheel groans". Not a huge problem yet as it's only noisy on a hard launch, if that's possible with the mighty 2.5n/a.
Im pissed at Subaru. The dealer replaced the clutch (previous owner) but not the flywheel just before we bought it and it was the first fault I picked with the car. They also never replaced the fuel filter.
Lazy IMO.
If I told you I was a compulsive liar, would you believe me?

Hey Frank,
Sounds good mate, pretty good effort there.
How do you do the clutch change? Split the box and engine and leave the gearbox in the car still, or do you drop it out?
Interested to hear how you're doing it - and if it's done whilst the car is on a hydraulic hoist?
I think my effort for a gearbox out job is 1 hr 40 minutes with a few extra sets of hands, that's being done with the car on axle stands. Once it's on a hydraulic hoist at a workshop I reckon 20 minutes. Amazing how much difference it makes with the right tools and a good hoist

Frankie. good to hear the white rx had the clutch changed, Im really interested in knowing what the clutch looked like? much life left or was it completely shaggered? Was the input thrust bearing in good shape? I know they can be a bit funny on the gen 3's as well sometimes.

Cheers Dylan, I believe it took me about 1.5hours to remove the gearbox (yes on a 2 post hoist) but because the box had redline (to new to waste) in it I decided to keep the tailshaft in it because I couldn't find an adequate bung to stop it leeking out. So part of the removal was whole tailshaft and exhaust/tailshaft shielding (bolted to the chassis). Only time I had some help was when I needed to steady the box on the jack for removal and placement. Gearbox Jacks and 2 poster's FTW.Hey Frank,
Sounds good mate, pretty good effort there.

I'm sorry I was under the pump and didn't take any pictures for a DIY.
Rhys, that clutch plate was McRooted.
I don't ever want to have to do it on stands ever again.

Can't wait till my clutch goes, got a fidanza 4.7kg waiting to go in. Get rid of the stupid dual mass. 
If it's broke use a cable tie.

B4's don't have dual mass flywheels. Why do you want a lightened flywheel in a car that is basically a semi-sport/grand tourer?Can't wait till my clutch goes, got a fidanza 4.7kg waiting to go in. Get rid of the stupid dual mass.
They don't improve the driveability of a car at all which kind of defeats the purpose of the mod, wouldn't you think?

How much lighter is the fidanza over stock B4?
Would this cause an issue when moving off from the lights? Less mass.

Really? I'd heard it was. It seems like one. To me it takes a long time to rev up and down, my KC laser revs up quicker.
It's not a daily anymore so i'm not to worried about drivability, i'm sure it cant be that bad once i get used to it.
If it's broke use a cable tie.

About 7.5kg. It's basically almost a 3rd of the original flywheel weight.How much lighter is the fidanza over stock B4?

Great to see someone elses experience with this, I have the same mod coming up shortly, already have an EJ22 flywheel, just waiting for the clutch to die.
Just to confirm, you did not need to change the clutch fork?
Did you go with a HD or standard EJ22 clutch kit? How do you find it?
Any other caveats to be aware of?
Cheers,
Jordan.

Its not the HD clutch that kills boxes. It's the retarded noobs that drive them.
Jordan's fairly experienced when it comes to Subaru mods and driving.

Hahahahahah, this thread is full of classic lines.I would hope no one is going HD clutch here.. HD clutch = new box... this is all
An NA hardly has the torque to worry a standard box HD clutch or not.
Alex is spot on, it's the driver that breaks things.
To the "Barron", I had an Exeedy clutch plate and pressure plate on an EJ22 I just bought.
The clutch fork and bearing stay the same as is in the Gen3. It's that easy.
Geez, I hope that clutch isn't HD.

Nice work Frank.
This "mod" is the best thing I ever did to my RX. The DMF was a POS. Luckily for me though, they replaced it under warranty!
