WTB: VW 020 RnP Looking for a RnP in 4:25 for a VW 020 transmission. They seem to be nearly made of unobtainium, other than a few mystery parts on Evilbay from England, So I figured I'd ask here first. https://www.rallyanarchy.com/phorum/read.php?7,103092,103092#msg-103092 Fri, 26 Jun 2026 14:55:33 -0500 Phorum 5.2.15a https://www.rallyanarchy.com/phorum/read.php?7,103092,103236#msg-103236 Re: WTB: VW 020 RnP https://www.rallyanarchy.com/phorum/read.php?7,103092,103236#msg-103236

The 3.89 final drive was fitted to some mk1 Golf / Rabbits and that gearbox casing does not have the mounting bosses cast into it to attach a mk2 / 3 rear gearbox mount to the diff casing. And that type of casing will also not accept 100mm inner CVs.

I thought the 100mm drive cups would fit the transmission but the outer CVs did not fit the upright without clearancing.

(This may also be a US market GTI thing, since ours always seem to be different in some way. And all of the restoration products seem to be made for Golf GTI not "Rabbit" GTI, but that's a topic for another thread/forum)

I bought a MK1 trans once (back in the days before I knew the difference), and found out that it had 90mm cups and no way to mount the case to the subframe. I did manage to put 100mm cups on after filing down the case a bit, and I made myself a custom bracket to join the Mk2 trans mount to the Mk1 case, and it worked out just fine.]]> Towona Buy, Sell & Trade Thu, 18 Dec 2014 11:32:38 -0600 https://www.rallyanarchy.com/phorum/read.php?7,103092,103214#msg-103214 Re: WTB: VW 020 RnP https://www.rallyanarchy.com/phorum/read.php?7,103092,103214#msg-103214 BobOfTheFuture Buy, Sell & Trade Wed, 17 Dec 2014 15:38:59 -0600 https://www.rallyanarchy.com/phorum/read.php?7,103092,103204#msg-103204 Re: WTB: VW 020 RnP https://www.rallyanarchy.com/phorum/read.php?7,103092,103204#msg-103204

"020 8V ring and pinion set will fit to your transmission!!!

But notice

In case you`ve got the "16V" type , you only have to change the fourth fixed gear , and go on like at standard rebuilding ."

So AGB is 22mm input, not 24mm?

I'm partial to the AUG myself, I think the 1.94 2nd and 1.44 3rd gives you the smallest gap on your most common shift.

Plus it's 8v trans, so works with all the FDs that seem to be the easiest to get.

Looks like an AGB box is the same as a 2Y. If that is true then the diff OD / crownwheel ID is 111mm.
Are you going to be fitting an LSD? If so choose one for an 8v application with 109mm OD as most lower final drive option use that size.

I wouldn't be building a box for rally use without an LSD of some sort. The two main weaknesses of the standard 020 box are the original / crownwheel rivets failing and the planet and sun gears falling to bits, both result in a fooked box and an expensive DNF.
One DNF costs the same as an LSD....

The car had a AGB with a quaife, but then popped a bit of aluminum off the case and a ton of oil into the clutch...

With the help of Kurt, we now know just about the whole gearbox is trash but the quaife. So the idea was to swap that and a better final into another AGB that he has to offer.

I'm nervous because the internet calls that box '16V'. But the internet also says the input shaft is a size it wasn't (as we dealt with earlier getting a clutch, John)

And seeing what the cost of getting a bit of gear over here, I guess I just wanted to run it past the guru's.]]> BobOfTheFuture Buy, Sell & Trade Mon, 15 Dec 2014 18:50:56 -0600 https://www.rallyanarchy.com/phorum/read.php?7,103092,103175#msg-103175 Re: WTB: VW 020 RnP https://www.rallyanarchy.com/phorum/read.php?7,103092,103175#msg-103175

My memory may be inncorect but I thought all the VW fan-boi types always blab about their "close ratio" was this

Memory still working ok there John. :up:

The term "close ratio" is commonly used in VW circles to identify the oem GTI gear set, as opposed to the oem "wide ratio" gear set used in less sporty shopping car models. It is not being used in a "motorsport close ratio" sense.
Both those close and wide ratio gear sets are listed in the quoted box in your post. However there are a few alternate ratios in the 2nd, 3rd, and 4th gears but 1st is always 3.45 and 5th no lower than 0.91 in oem gears.

The 3.89 final drive was fitted to some mk1 Golf / Rabbits and that gearbox casing does not have the mounting bosses cast into it to attach a mk2 / 3 rear gearbox mount to the diff casing.

Do the match: 3.9 to 4.2 only shortens the final drive a little bit--

The stock 16v and 8v GTI boxes that everyone uses are 3.67 so going to 4.25 is a bigger jump than you suggest but still problematic. With a 16v 5th gear (0.91) you end up with a top speed of like 130+ mph which is too high.

Also something to note is that the crownwheel IDs can vary. 109mm and 111mm. So if you have a 111mm OD diff from a 16v with 3.66 FD, then it will need machined down to accept a 109mm ID crownwheel.

EDIT: And if using a standard 2Y code 16v gearbox with 3.6 FD and converting to a lower FD, then 4th gear (1.12 ratio) needs to be changed for a gear from an 8v box as the pinion shaft is a different diameter where 4th gear runs.]]> danster Buy, Sell & Trade Sun, 14 Dec 2014 16:02:17 -0600 https://www.rallyanarchy.com/phorum/read.php?7,103092,103110#msg-103110 Re: WTB: VW 020 RnP https://www.rallyanarchy.com/phorum/read.php?7,103092,103110#msg-103110

By far the weakest part in an 020 is the reverser gear. You need to come to a complete stop every time reverse is engaged!!!! Any metal that comes loose inside the box will immediately get picked up buy the ring gear. There is a small screen insert that can be added to prevent this.

Another important fix on the Golf is to add steering rack travel limiter collars. 8 to 10 mm thick will help to prevent CV joint failures.

I built an 02A with the Czech gear kit. The kit consists of modified VW parts welded together. It held up Ok.

FYI, Don't put a turbo on Golf rally car.

Robert, do you have any more info on this screen and where to find one? I'm about to open up my 020 to refresh the clutch pack in my KAAZ, so it would be a good time to add one.

FYI, I run a 4.81:1 FD which works well with my 175/70R15 (aka 62cm dia) tires. In my AGB transmission it tops out at just over 100mph. If I were starting from scratch I would go 02A, but between the FD and KAAZ I have too much invested in this box.


Boys pay attention here!
62cm tire is the ticket...and that is a bit taller---gears you UP.
So if you don't have a pile of 20-30 14" wheels go 15".
Corrado brakes will fit under 15 and they pretty darn good and pretty darn good is pretty darn good.
So if you go 62cm tire that's why I's saying 4.67 or even a tad shorter if you can find it...
100-105mph at around 7000 is plenty--the VW motor laughs at a mere 7000...
The main thing is you'll have better accelleration right up to top speed...

'member we don't go O to 60 all the time but we go 40 to 85mph about 10,000 times per event
Good torque and some gearing for some harder acc 60-90 ain't a bad thing..]]> john vanlandingham Buy, Sell & Trade Fri, 12 Dec 2014 12:41:49 -0600 https://www.rallyanarchy.com/phorum/read.php?7,103092,103102#msg-103102 Re: WTB: VW 020 RnP https://www.rallyanarchy.com/phorum/read.php?7,103092,103102#msg-103102

And minimum 4.47 or whatever, maybe shorter.
