i basically bought 3 new ones (my old ones were mint and now live on bens Red car)

As i say, only the drivers rear one is a different part number.. the TDI and ABF use this item.. other 2 are same as 8v.. you need this set up

it was around 200 quid at the main dealer for all 3. i think you can get them at Eurocarparts from about 120 all in  (or maybe you could get that mate to get you them at cost price ? )

all mounts are the same shape, vr6 used to be more heavy duty but now they are ask the same (or at least febi ones are) tierod is a great seller its all oe spec, the mounts I got of him were febi
Its up to you though some people don't trust cheap sellers, tierods a well known seller in the vw community though :)

No need for vr one on front of the 20v lump tho. The drivers rear one on vr6 is NOT heavy duty like it is on the 16v and TDI. vr6 uses same as 8v on both rears because most the Weigjt is over the front. It's not the case for the 20vt so I'd deffo go the 16v route but it's up u guys at the end of the day  :nerd:

Right then - digging this back out as no need to start another thread!!

Since looking at doing this project the funds have come available for me to do it right the first time so I am going to take your advice and get the abf box!

What gearbox code do I need to look for? or is it just any 2.0L 16v gearbox with hydro clutch and cable gear change?

Also I will be posting pics of the turbo and inlet manifold so you can all see the cleaning progress!

Cheers

all 02a box's are cable change hydro clutch, you want to look at the ratios more than what car they came out of. The CDA/DPA box's are fine in a 16v but that is an NA engine with low torque and so the ratios are set out to give the best performance for that engine.

The 20vt is a turbo with LOADS of torque especially when put into a mk3 so you want a box designed for a car with more torque, which as far as the 02a goes is an ASD box from a 1.9 TDi. There are other more expensive options but I think if you ask around or do some google searches a majority of people will steer you towards an ASD box

have a read of the transmission faq over on clubgti if you want more insight into gearbox ratios etc :)

here is a post tshirt2k when we were discussing which was better suited DPA(abf) box or ASD

I did max revs at 6500 and 195/50-15 tyres. Your car may not be able to pull 6500rpm in top.

This is using Quaife calc

Gearbox:-  ASD
Tyre:-       195/50-15
-------------------------------------------------------------------------------------------
Top Gear gives 29.811 MPH/1000 RPM and a top speed of 193.770 MPH at 6500 RPM

Engine speeds in top gear:-
    30 MPH = 1006 RPM   40 MPH = 1342 RPM   50 MPH = 1677 RPM   60 MPH = 2013 RPM
    70 MPH = 2348 RPM   80 MPH = 2684 RPM   90 MPH = 3019 RPM  100 MPH = 3354 RPM

Top Speed in 1 gear = 42.101 MPH
    And changes into 2 gear at 3829 RPM dropping 2671 RPM
Top Speed in 2 gear = 71.468 MPH
    And changes into 3 gear at 4373 RPM dropping 2127 RPM
Top Speed in 3 gear = 106.218 MPH
    And changes into 4 gear at 5114 RPM dropping 1386 RPM
Top Speed in 4 gear = 135.017 MPH
    And changes into 5 gear at 4529 RPM dropping 1971 RPM
Top Speed in 5 gear = 193.770 MPH
******************************************************************************************
Gearbox:-  ABF
Tyre:-       195/50-15
-------------------------------------------------------------------------------------------
Top Gear gives 21.914 MPH/1000 RPM and a top speed of 142.444 MPH at 6500 RPM

Engine speeds in top gear:-
    30 MPH = 1369 RPM   40 MPH = 1825 RPM   50 MPH = 2282 RPM   60 MPH = 2738 RPM
    70 MPH = 3194 RPM   80 MPH = 3651 RPM   90 MPH = 4107 RPM  100 MPH = 4563 RPM

Top Speed in 1 gear = 36.129 MPH
    And changes into 2 gear at 3829 RPM dropping 2671 RPM
Top Speed in 2 gear = 61.330 MPH
    And changes into 3 gear at 4373 RPM dropping 2127 RPM
Top Speed in 3 gear = 91.151 MPH
    And changes into 4 gear at 5114 RPM dropping 1386 RPM
Top Speed in 4 gear = 115.865 MPH
    And changes into 5 gear at 5287 RPM dropping 1213 RPM
Top Speed in 5 gear = 142.444 MPH
******************************************************************************************

As you can see from the numbers you will get a lot more out of the engine with the ASD box, though it looks like 5th gear will be very long some might say too long. I thought about this when fitting it but once in that all went out the window, its so much nicer to drive :) 1st-4th are pretty much the same as 1st-5th in the DPA box, and he ASD 5th is a nice cruising gear. You can see with the DPA you will be at 100mph in 5th at 4563rpm, whereas with the ASD you will be at 100 at only 3354rpm, thats a big difference! Plenty of times I've been cruising along the m25 in 4th and suddenly realise I've got a whole other gear  :cool:

the numbers above might be a bit unrealistic as I dont know about you but I never go to 6500rpm, but if you get the ratios from any box on the clubgti transmission faq and put them into a gear ratio calc you can set your own rev limits etc and get your own results :)

reading this back to myself it may seem im being a bit biased towards the diesel box, but I had the DPA box in mine for 7 months and loved it before changing to the ASD box, and the difference really is enough to say it was like doing the conversion over again  :cool:

Thanks Dan - That info if great!

If I have read this correctly then you would have put the ASD box from the diesel on first time round?

If thats the case then I can get hold of that box very easily! Does the diesel box really drop the revs in 5th?
