what drive shaft options if wanting to fit 02M gearbox?

[lowvr 0]

as title says really, as i cant find a definitive answer

obvious place to look is drive shaft shop and pay $$$$$ so wondering what spec is required and weather there are more cost efficient alternatives

[FishWick 21]

Yeah but bear in mind the DSS ones can handle 475whp, which for £500 I think is quite reasonable personally :-)

I have heard of an Audi S3 inner CV plus MK7 Polo GTI shaft and Outer combo, or something along those lines, and some rumours of shortening and what not.

I'd rather fit new shafts than cut and shut old ones personally!

Hopefully MaidenVR6 will chime in as I know he's fitted an O2M.

you do have a a point there kev

whilst you're can i ask you one more question then:

i was on the corrado-net where the stealth racing talks goign on at the moment and notied an interesting post from you mentioning recasing an 02m into an 02a...i didint realise this was possible as didint realise it woudl physically fit

can you please elabortate a bit and give me todays dose of education

thanx again!

[FishWick 21]

Yeah, so any O2M car (S3, Leon Cupra R, R32 etc) can donate it's inner CVs and you can use MK3 or MK4 outer CVs, but it's just the shaft joining them together that I'm not sure about!

Anyway, for today's 'lesson' then, O2M gearboxes, LOL! :-)

You can't fit 02M gears into an O2A unfortunately, the gears are physically too big and and there's too many of them!

What I was referring to in that thread was recasing a 4WD O2M into a FWD one :-) 4WD O2Ms are the only choice we have unfortunately, but you can buy a FWD O2M bell casing from the dealer oddly enough, and then rehouse the gears from the 4WD one into it.

The cheaper option is to remove the transfer box from the 4WD one and plate over the hole, but that's pants imo. It's a hash job. I prefer to use the proper kit personally.

A good 4WD 02M stands you at £200-£250. A FWD 02M bell casing is £300 from the dealer and you'll also need a second hand FWD flange from a Leon. A day's work and £500 you have a proper FWD O2M :-)

Then of course there's the fitment issue and the driveshafts.

Assuming you go with the DSS axles, that's £1000 for those and the box.

How much is a 6 speed gearset for the O2A? Approx £1500!

So for £500 less, you get a stronger box that's OE and has tonnes of spares around in breakers yards :-)

Fitment isn't difficult for a competent welder. It's an engine out job, so can be a "Whilst you're in there" excercise too!

excellent, that makes a lot of sense now

I guess the next step to have have the gearbox vrT friendly would be:

- lsd £600

- change to longer final drive (not sure of cost of that item)

- and the rebuild for that - all depends where you do that or weather you do it yourself ( i dont think im ready for gearbox diy work yet)

by then end of that you could a gearbox that would theoretically capable of being to withstand mroe power than you need

- i think i need to consider this - and if ii do probably factor in a short shift now that i can't live without it

im using a om2 with shortened shafts aint drove it yet but the cost 90 each to shortern if thats any help im also using all m4 cv joints

[lowvr 0]

thats definately helpfull

where did you get them shortened and also when do you think you are going to get to test the car out?

[Phat VR6 3]

theres a few 4 wheel drive turbo VR6 around with standard shafts shortened.

CV joints are the things that normally brake

[john555 0]

mb motorsport did mine but they need the car to do them dutchbuild will shortn hollow shaft for around the same price thou i wont be driving mine for another few month but there another lad on here with a similar setup to mine he has a build thread in the members ride section

[sharky_70 0]

sorry to hijack, but am i correct in thinking that the mk5 R32 box is the one to avoid? as it takes the speed from the wheel sensors rather than a worm drive on the casing? or am i way off

[FishWick 21]

Yep, that's correct and the dutchdub bracket doesn't fit it either.

[sharky_70 0]

hhmm thatll be why its for sale then i suspect!

[FishWick 21]

Is there one for sale? Can't see it?

I mentioned in a different thread, but you can convert it to FWD with the bell housing p/n - O2M 301 107G

That housing uses the mechanical worm drive for the speedo, so job done!

£300+VAT though. But, I got <1000 mile MK5 box for £200, making £500 for an OE FWD 6 cyl 6 speed box quite cheap overall. Costs 3 times that just for a gearset for the O2A.

When 4 motion box supplies dry up, it may be our only option, unless someone comes up with a circuit to convert an ABS sensor signal into one the mph guage can understand.

Or it might even be possible to modify the MK5 bell housing to fit the worm drive gear?

on another forum Kev

well still somehting im considering but i think you mentioned in the 6 speed 'box thread (which i cant find) that running this box on a car with low pro 17" wheels is gonna knacker the top end anyway?

[MaidenVR6 26]

DSS axels are expensive. They are 100% bolt on. They are very well made, and DSS have very good support.

I have converted a R32 02M into a fwd 02M, and the DSS axels is plugn/play.

I didnt wanna screw around with welding stuff togheter. I knew DSS would work, and it has. I push 30 psi on the car, and I dont have any issues. At all.

[Phat VR6 3]

there more than one way of doing it

some more expensive and easy with peace of mind..

others cheaper. imo the drive shaft its self very rarly fails.. its more the CV joints.

a properly shortened drive shaft will be as strong as the original if not stronger... after all its near enough the same process... oem ones are welded.

once you know the length you just drop them off. pick them up and there plug and play

[FishWick 21]

Depends on the cost of the shortening really. The DSS axles come with stronger CVs and ready to bolt on as Maiden says.

These gearboxes are getting on my nerves now, LOL! I found out that R32s and 4 motions got an 02M up to 2007. Then they got an 02Q manual and the 02E DSG.

The 02Q has some internal differences to the 02M to improve the shift quality, plus some minor casing alterations (including the deletion of the speedo drive).

According to SQS, the 02M and 02Q casings are not interchangable, meaning if you have an 02Q, the only option is the EOS R32 FWD clutch casing. I'm not so sure about that myself. I can't see VW changing the bolt pattern from the 02Q and 02M as they're near identical externally.

I think the O2M casing will mate onto the 02Q box, but I need a spare 300 notes to find out, LOL!

I'll keep you posted. I'm convinced this can be done cost effectively and to OE standards.

[MaidenVR6 26]

The fwd shaft I needed to my 02M is from a fwd 02Q. Perfect size:)

[matty.vrt 120]

what sort of power do you make with 30 psi

[FishWick 21]

Probably 500-550whp with a GT35 on "pump gas", but they use E85 over there, so possibly a little more.
