Title: mk4 Gearbox for 1.8t conversion
Post by: CJA321 on 17 May 2012, 13:19
Okay so iv bought a AUM 1.8t will all driveshafts gearbox engine and all the rest to do the conversion. Gonna give it a bash and see how i get on.

What i want to know is do you need the ABF gearbox or will the box for the AUM work as the engine also comes with shafts and engine mounts and gearbox, just wondering as may save sourcing the rest of the bits.

Cheers

mk4 box will fit fine 02j is the same physical size as the 02a (dont take this as gospel but im 99% sure its correct), people go for the 02a as the ratios suit the mk3 better in general

brad is using an 02j in his so I'm sure he will be along shortly to confirm :) It may be worth getting another box though depending which 02j one you have as gearbox ratios can make quite a drastic difference to the engine performance

Right okay, i did think this.

Its just iv read you need ABF Mounts, Hydro and Box. But seeing as the engine iv bought comes with all this, was hoping they would work as you have confirmed.

Going on this, I do assume that the o2j mounts will be okay then, and ABF will not be needed?

But as youv said, if the ABF is better suited, i'll run that. Or do you run the o2j with a different final drive or something?

Save me going out and buying a doner anyway  :tongue:

Mk3 driveshafts will be fine and the mk4 box will fit, but you will need the mount brackets from a ABF car mate

im switching to a mk4 box which is exact same ratios as the mk3 16v box but I'm swapping final drive out to a VR6 one for longer top end and I'm also fitting the Wavetrac LSD (Expensive)

iv also got Audi TT short shif and MK4 gear selectors which need modification to fit mk3


for easy and simplicity, you would be best just to fit the full 16v mk3 set up. (you could still use your mk4 box, just use the other bits from a ABF - may alos need the Tower from the gearbox of the 02A if u do this

you will need the ABF hydro parts really as the mk4 ones are different shape piping but it could all be made to fit, iv just not done it (the MK3 abf Slave cylinder on the gearbox fits the Mk4 box too)

I think for the simplicity and option of getting some money back, i'll just get a 16v doner then if thats what you recommend.

And sell on the mk4 box try make some money back from that too, thanks for the advice
Title: Re: mk4 Gearbox for 1.8t conversion
Post by: CJA321 on 17 May 2012, 19:32
Or would it be wiser just to buy an ABF box with mounts? Or do you actually need the brackets on the chassis? Just suming up my options  :wink:

I know brad loves his 16v box but I would seriously recommend getting a box with taller ratios such as the box from a mk3 diesel. The 16v box is designed for 16v engine which has relatively low torque, whereas the diesel box is much more suited to a turbo engine which has a lot more torque and really thrives with the longer gears

your choice but I'd suggest looking into more info on gearbox choice as its quite an important part of your set up :)

I thought the ABF o2a and the AUM o2j had the same ratios? Wouldn't that mean its quite suited for the turbo? I do like your idea though, Only thing im struggling on ATM is gearbox and how to set up the mounts. As in whats needed for it, do you need to weld new brackets on also?

Brad has also said he is fitting a VR6 FD to lengthen the gearing. 3.68 to 3.3 IIRC.

No welding.
Just use Mk3 16v gearbox mounts...the O2A and O2J 'boxes share the same casing.

yeah hes doing that to his 02j box but up until thats fitted hes running a standard 16v box i believe, the wheel spin must be mental :P

all 02a and 02j ratios can be found in the clubgti transmission FAQ, give it a read its very informative as is the rest of the gearbox and 1.8t engine section to anyone doing a conversion :)

thats correct, i am surprised Dan went for the ratios he did TBH and didn't just do this too, the ratios of the 16v box are pretty dam perfect for the 1.8T (wheel spin is present tho as said, unless you really feather in the power), the VR final drive will make it as perfect as you can get for sheer performance, pick up etc, well that coupled with the wavetrac LSD

Its getting sent to Martin (Hotgolf) next week so ill let you know the outcome of it all.. iv been working hard with him and i trust his opinion.

My 02J is getting fully rebuilt by martin so its basically going to be like a brand new box

also fitting a lightened Flywheel at the same time. can't bloody wait :-)

My full mk3 set up is for sale, cable shift, Tower (refurbished looks mint) and early 1.8T shift weight.. think Funkyfive off here is buying my 02A box tho

See id be interested in the whole set up if it came with the box also!! Would mean only need to source mounts and hydro!!

Only thing im worried about is the wiring.... Everything else not a problem. Do you run OEM managemant?

Going from memory here so don't quote me but if I remember right the asd box has the same ratios as the dpa 1st-4th and just has a longer 5th and final drive, so if you put a vr6 final drive into a dpa it would be similar to the asd you would just have the nice long 5th for cruising (90mph just under 3000rpm)

Each to their own though mine is imo perfect for my setup but I don't have the bam like brad just a puny aum :p

Right, looking into which box im going to use and decided to stick with the 16v box from an ABF as Brad has suggested.

Will any ABF box do? Or looking for a specific code?

CDA + CGN are on http://boneybradley.webs.com/thegearboxes.htm

But been reading some posts on using a DPA, but cant seem to see it on there.

Just dont want to go buying a 16v doner and it being useless.. Cheers

CDA and DPA are the same, except one is a Ibiza Cupra Sport 16v 'box, so runs a cable clutch...which may be ideal for you as it would save you changing to a hydraulic clutch.
I think that may be the CDA...I think a Golf 16v is a DPA (might have got them the wrong way round)

I've never heard of a CGN.

well funky five has not got back to me on my box

iv looked on the bay and they are going for between 80 and 200 quid for the DPA  :shocked:

i can let my box (painted Satin black so all the bits you see look good :cool:) for £80.. it has had a rebuild at some point in its life and i removed it from my old 16v car personally so i know its been looked after.. i also only run high quality oil.. currently has Mobil 1 fully synthetic in it
The box has done 95k miles but as i say it was rebuilt by a previous owner (i have only his word on this but it has zero issues at all and silky smooth gear change)

i will include the tower for this price too or sell if for £70 without the tower

if you want my gear shift cables id do a deal at £100 for the whole lot.. no offers as this is a bargain for very good condition used parts that look good too with been clean and satin black

I'm based in Leeds area and they will be coming off my car in around 3 weeks time

the only part i won't have with my box is the small mount bracket that joins the box to the mount on the subframe (i still need this bit) but these can be picked up easily..

not trying to cut in by any means just saying about the prices, I dont see how any of those box's on ebay can sell mines been on there for over a month at £50 and its only had around 15 views! £80 is a good price for a good box though mine has unknown history and looks like sh!t  :grin: needs a good clean before it sells (if it ever does)

gearbox bracket part number if you need it is 357 199 353 there are a few on ebay now if you search that part number
