I need some 02M vrt insights

[pimS]

After debating for some weeks on selling my VRT, i decided to keep it
But im planning on selling the 02S and switching to 02M.

I got a good price on a 02M with about 30k on it, wich i'm picking up this saturday.
The owner has some more stuff laying around flywheel, clutch etc.

But i'm debating on what i can use. i've read about the duall mass flywheel not being capable of handeling more than +/-400 hp, is this true?

Should i also take the clutch and flywheel?

Im running 389whp/460nm, and that number will most likely increase to around 500whp.
I hope you guy's can give me some insights on the OEM 02M parts.

Im in the middle of my o2m vrt swap right now so I cant help you much with the results but I can help with what I'm planning as I've already had experience with the o2m in my bt 1.8t. The bt 1.8t is stock clutch/dm flywheel and is/has been putting down 400hp/350ishtq for the past 3 years and it has 90k miles on it total. It has just started to slip recently during 4th and higher pulls, this car hasnt seen any track time.

I bought an o2m swap for my corrado and with it already having a peloquin, I figured it already had a decent clutch to go with it but it still had stock clutch/flywheel. Said hell no , and ordered up a south bend stg3(used to be called 4)SS OFE clutch with flywheel. Full face disc rated for 475 which is what I'm shooting for at the wheels with 6262/c2 630cc combo. I plan on running this car at the strip and the roadcourse but not making a living off either. The clutch/flywheel was not cheap but when you fit the o2m in there, you definitely dont want to pull it out again

I've run the same 02m in the mk2 for 6 years. Aside from the short gearing, it's the strongest I've encountered.

I wouldn't use that dual mass for high torque, but it does take a lot off the driveline for street cruising. If you ditch the flywheel, you can probably compromise with a sprung hub disc, but its limitations will be determined by the manufacturer.

I don't know what chassis you plan to cram that into, but anything Mk3 and below takes a little fabricating. In fact, I think there's a thread in here somewhere regarding that swap.

Regardless, I don't believe you'll regret the work in the end.

I researched the hell out of this when i did my o2m setup last year. Took months to make a final decision and collect enough info. general consensus is, the DM fw is a bad idea if you plan to make some power. longevity becomes an issue/ along with the possibility of catastrophic failure. boost will wear out the DM quickly...its not exactly designed for holding 4-500+whp etc. especially in a swap situation like the corrado, its not just "drop the trans" when something goes wrong, The whole assy. has to come out, as I'm sure you know.

light weight flywheels really suck for use w/ the 02m. Clutch chatter is nasty along with major gear lash. Stock weight, single mass FW if the best option IMO for the 02m. I had a hell of a time finding someone that made it. I was about to have a machine shop turn one out for me. I called many places and found that Eurospec makes this exact FW for the vr6. I had to special order it ( around $300) but well worth the wait. I had the fw and PP balanced together for a nice smooth rotating mass. For a clutch, I did Clutchnet 2xpp and full face copper feramic disk. Im making around 550whp fwiw.


With that said, I highly recommend the single mass stock weight. you'll be very happy w/ it. im a picky ****in guy and have no complaints about my setup. sorry for the novel, just wanted to share my exp. since this was an issue for me also when i went 02m.

heres a pic of the FW:

Thanks for the info!
Let the search for a single mass begin

I bought my flywheel from fourseasostuning, its steel billet, weighs about 20lb, it does chatter but I dont mind it, Think I paid around $400 shipped for it a year ago. As for clutch I have a southbend stage 5 in there, its full face ceramic unsprung. It grabs hard, its like a on/off switch, but thats what I was looking for. Combined with the dieselgeek sigma short shifter, it transferred the car completely, feels like a whole new beast. Not sure what you're doing with driveshafts, but I went with 800hp DSS shafts, set me back around $1k, but at least I have no real weak points now. Just waiting on lugtronics now and put this setup to test, planning on making around 600whp.

i welded my dual mass fly wheel up been running 3 years with no problems my buddy has a
billet fourseasostuning flywheel and has gearbox chatter at idle
the driveshafts i used is short shaft off the mk4 pd tdi part number 1j0 407 271gc
the long shaft from a 2005 seat ibiza asz engine 6 speed or fabia vrs part number 6Q0 407 272 CL
is a bolt on fit (mk3 golf vr6)

i fitted a cheap 2wd obx diff into the 4motion box and this is still going strong 28psi daily 3 years i did rebuild it with quality springs and thread locked the new bolts

Hopefully you had the dual mass shaved flat and balanced after welding. Sounds like a decent/cheap alternative to get by but kinda sketchy long term wise.

i did not have it shaved flat althought that would be best idea if welded wrong ..
what i did was pack with shims so it was equal all round then i put a big bolt threw the centre to and tightened it up to nip onto the shims then i put 4 tack welds on then removed the bolt and hammered the shims out .i balanced a crank on a balancing machine then fitted the flywheel it did not need any balancing here is a crappy vid off nokia 6630

02M is the way to go with VR6 Turbo. Just be sure to get a clutch that will hold the torque. Just do it right the first time. That said, a twindisc setup should be the way to go when you have some power in your engine. A low boost VRT "15psi and below" you can use almost any 02M clutch you want.
So many R32 Turbos that have singel disc setups and it breaks after a while. Why cheap out, and buy problems, when you can spend money and get something that hold


Be sure to get a good gearbox mount. I needed to get a new gearbox because all 3 threads in the casing is completely broken.
Now a DRP is going in, togheter with a DLITeknik mount and a dogbone under the car.

Picked up the tranny + a starter this saturday, the guy where i got it also has a shifter tower etc, so i'm also picking that up from him.
Ran into 2 part numbers for stock VAG axles that fit a mk3 setup, i have a big chance of finfing them at the local junkyard.

I also found a chromoly FW @ a german shop, it's around 6 kg, i"ll search a bit more to see if i can find a heavier FW(in europe).
As for a clutch: im leaning towards a clutchnet red PP with extra clamping load, + a six-puck spung disk.

hahaha i totally forgot magner posted it in my own thread

Oh yeah , another question:

What is the difference between a 24V and R32 clutch? They are priced differently on a lot of sites, but they both use the 02M...

[magner]

there is a short shaft on ebay here but its in uk
http://www.ebay.co.uk/itm/SEAT-LEON-...item3cc15e1a99

or this one twice the price with nut a bolts if you want to pay more

[masterkey79]

Hi! I'm too in process of installation of 02m into Mk2, but stuck with gearbox rear mount.
Does anybody has measurements for movement of rear support on the k-frame ?

And if anybody have any drawing of support that's need to be make, could you share a little info.

Thanks in advance.

BTW.: if you use 4 cilinder disel/gas engine, you could use complete set from Audi TT Quattro 6 speed, as they have same measurement

[pimS]

No one knows the 24v/r32 clutch and flywheel difference?

[DannyLo]

Stock clutch in my 24v o2m slipped at 7psi with my precision 6265. The car had 50k when I turbocharged it. The clutch looked brand new when I took it out, just couldn't hold.

FX400 ever since and it's been delightful Seriously smooth, and even pretty damn quiet with the aluminum flywheel that I went with instead of steel, which would be even quieter, and smoother.

I'm not sure of the differences between r32 and 24v if there even are any...i'm sure someone will chime in.

[marat_g60]

From what i know, the clutches are the same but the flywheels are differrent. Contact james at fourseasontuning he sells them so he'd know better.

Same here - FX400, but I went with a steel flywheel. It's a tad chattery.... but you don't notice it unless you really listen for it. This setup is super smooth..... easy to drive for a daily application
