Title: Gearbox
Post by: Mcwill on 07 January 2014, 23:34
Running the 8v gearbox on my mk2 abf but don't like the gear ratios as it feels sluggish in the gears almost like there to long. Been looking on the net and there seems to be lots of options and opinions on what the best set up is but nobody seems to agree.
I don't want to change to hydraulic set up so what's best to go for, 02a seems to get mentioned a bit?
Would it be worth getting 8v box rebuilt with different ratios?
Any advice would be great thanks.
Title: Re: Gearbox
Post by: Mcwill on 11 January 2014, 07:39
Anybody?
Would it be possible to have the 8v box reconditioned with different gear ratios? And what sort of power can that box withstand?
Any help or advice would be great.
Title: Re: Gearbox
Post by: dai-cymru on 11 January 2014, 08:14
The cost of getting the ratios changed I would suggest its prob cheaper to source a good o2A box and fit that
Title: Re: Gearbox
Post by: Mcwill on 11 January 2014, 13:57
What golf is the 02a box on and is it cable clutch?
Title: Re: Gearbox
Post by: weazgti on 11 January 2014, 20:40
I ve read that people think it feels slower with the 02a box compared to the 8v. I mean obviously it will last with the correct gearbox but it sort of put me off changing mine. I have same as you 8v box on abf lump. O2a in the shed still.
Title: Re: Gearbox
Post by: Mcwill on 12 January 2014, 01:45
With mine as it is at the mo I'm getting about 60mph in 2nd 80mph 3rd 100mph 4th and 133mph 5th. Dose that sound about rite?
Any guys out there running 02a box on abf lump? What you guys get?
Title: Re: Gearbox
Post by: weazgti on 12 January 2014, 10:31
I get nearly 95mph in 3rd @6900rpm with 8v box although I wouldn't trust the 24 year old clocks in it.
No idea wot it does in 4th because it's the Isle of Wight and only short blasts.
Title: Re: Gearbox
Post by: gazareth on 12 January 2014, 19:23
maybe your engine needs fine tuning? for all the difference there is in the ratios I would just leave the 020 in until it falls to bits. maybe the engine is still a bit tight after the rebuild.
Title: Re: Gearbox
Post by: Mcwill on 12 January 2014, 21:41
Not sure what to do? Think ill leave for now and let engine get a few miles on it.
Was thinking of taking it down my local rolling road and having it tunned but seems bit pointless until I get gearbox sorted.
Title: Re: Gearbox
Post by: gazareth on 13 January 2014, 00:46
 I think your just not revving the engine hard enough :wink:. I would get it on the dyno first just to make sure its making good power. the gearbox may not be the issue.

We should line up on the Julie at some point to see how much quicker off the line your Golf2 ABF on rod-change is vs my Corrado ABF on an 02A.  :whistle:

95mph is about the limit anywhere on the island :grin:

To be fair, an 8v motor feels lively on an 8v box, can't see why adding another 50hp would make the drive feel sluggish  :undecided:

So just to sum up, I need a o2a gearbox and that's of a mk3 gti? And would I need to change the pedal box? And dose that fit straight on? Sorry guys I need help it's all very confusing for a novice :huh:

Very helpful spreadsheet, used it for finding a final drive to help shift the tug boat a bit better amongst other things.
Hope this helps with your ratio conundrum :smiley:
I have made my own from it lining up direct swaps between models :nerd:

Post by: Mcwill on 15 January 2014, 21:42
That is a mind field of numbers.
Rite had a good look through that and I think I'm after a mk3 gti 8v che,dfq or amc gearbox. Looked on ebay and is a few up for sale.
So what I need to no from guys in the no is would one of them fit my early model abf?
Would I need a new clutch? Running the mk2 8v one at min.
Would the clutch cable be same?
Would the mk2 speedo cable fit?
Help me chaps I'm going mad here  :shocked:
Title: Re: Gearbox
Post by: gazareth on 15 January 2014, 23:39
well with the standard 8v gti box if you could get to 7krpm in 5th you would be doing 147ish mph. but if you gear it up its gona feel slow through the lower gears. you may have to think about a six speed box.
Title: Re: Gearbox
Post by: Mcwill on 15 January 2014, 23:50
Another option that's for sale on ebay is a g60 gearbox code cba, fast through the gears but longer in 4th and 5th. 156 mph in 5th :laugh:
Title: Re: Gearbox
Post by: gazareth on 16 January 2014, 00:12
the 8v gti box is closer ratio than the cba box which is better suited to a revvy 16v engine. it all comes down to how you want to drive it though. top speed or acceleration???
Title: Re: Gearbox

Title: Re: Gearbox
Post by: Mcwill on 16 January 2014, 15:31
I've done about 1000 miles in it since rebuild so yeah it should be.
Title: Re: Gearbox
Post by: Gambit on 16 January 2014, 16:50
did you ever find out what the code is of the box currently fitted? just because you think its an 8v box doesnt mean it is....i once had a 16v that came with a Maestro box - yes an Austin Maestro box!!
Title: Re: Gearbox
Post by: Mcwill on 16 January 2014, 18:47
Haha my dad used to have one of them, heap of crap.
Think it's an 8v as it was a 8v clutch that the garage got for it when they did the engine.
It's maybe me thinking it was going to be faster then it is. :undecided:
But I have seen some YouTube vids of abf mk2s and they look faster.
Title: Re: Gearbox
Post by: Gambit on 16 January 2014, 20:38
Your missing the point. All 1.6, 1.8, driver, gti, gl & diesel all use the same 8v clutch on a variety of gearboxes with different ratio's and all boxes fit hence until you get the gearbox code of the bottom of the bellhousing you dont know what is in it
Title: Re: Gearbox
Post by: Mcwill on 16 January 2014, 21:35
Ill find out what code it is next time I'm under the car.
What gearbox/ code would you use gambit?
Title: Re: Gearbox
Post by: Gambit on 16 January 2014, 21:43
You'd want an AUG box imo - closest to a 16v box but with a slightly longer 5th

this is a listing of all rod boxes and their ratio's ( http://www.scirocco.org/gears/) hence find out what yours is.
Title: Re: Gearbox
Post by: Mcwill on 16 January 2014, 21:52
Thanks for that bud. Would the AUG box fit straight on?
Sorry for my lack of knowledge mate, still learning.
Title: Re: Gearbox
Post by: Gambit on 16 January 2014, 22:17
Yep, they all fit straight on. Only the 16v box uses different clutch
Title: Re: Gearbox
Post by: Mcwill on 16 January 2014, 22:20
Brill thanks for that.
Title: Re: Gearbox
Post by: gazareth on 16 January 2014, 23:29
it should have had an aug fitted from the factory but there is a chance its been swapped at some point.
Title: Re: Gearbox
Post by: VW BUSH on 16 January 2014, 23:43
A 3.9 or 4 fd will give you what you need on most of the rod and cable change boxes.
Best mod to make it feel faster imo, and to make a mk3 faster is quite something
Title: Re: Gearbox
Post by: Mcwill on 17 January 2014, 00:07
I think 1,2,3 on mine at the mo is not to bad its more 4,5 that I'm wanting more speed. I spend most the time on the motorway.

Was reading somewhere else on the net that ATA,AGC,AYL and AYK of the corrado g60 or passat 16v is a good box to use on the abf they also said if you use g60 flywheel will make it feel better due to the flywheel being lighter. Any body else agree with that? Any thoughts Gambit?
Title: Re: Gearbox
Post by: Mk2Kezza on 01 February 2014, 18:19
If its better cruising economy you're after then:

I had an AUG box on my golf and had an 80 mile round trip to work so swapped out the 5th .89 cog for a .75 5th gear cog from a 4T box. Had the close ratio gears 1st to 4th then an ‘overdrive’ 5th. She used to return 45 mpg regularly on a run at 75 mph.

that's the same set up I had on my last mk2 but the gap between 4th and 5th was massive. I put a .80 5th gear from a mk3 golf 1.4 cza gearbox in my current mk2 and that seems a good compromise. same 5th gear ratio as a che/dfq gearbox but it doesn't need the fancy circlip retainer thingy.
Title: Re: Gearbox
Post by: Mcwill on 01 February 2014, 20:55
Thanks guys still unsure what to do, there is a g60 box on ebay I have been keeping my eye on but in two minds :undecided:
Title: Re: Gearbox
Post by: Diamond Hell on 03 February 2014, 10:39
WHOAH WHOAH WHOAH WHOAH!

Before you run off down into discussing Passat 16V and G60 boxes remember that you're going from rod-change to cable-change which means a completely different shift assembly, to the stick in the car, different front engine mount bracket, starter, flywheel, clutch, clutch actuation method, and the long driveshaft is shorter etc etc etc

Now, do you want all that, or do you just want slightly different gear ratios in your car?
Title: Re: Gearbox
Post by: Mcwill on 03 February 2014, 12:24
No i don't want all that, not at all. Pleased I dint get it now.
So would it be worth getting the box rebuilt and just change 4th and 5th?
I have no idea :huh:
Title: Re: Gearbox
Post by: Gambit on 03 February 2014, 16:43
did you ever check the code of what box is in yours? do that before you do anything else
Title: Re: Gearbox
Post by: Mcwill on 03 February 2014, 22:05
No I dint gambit but I will do. The more I think about it the more I'm thinking of just getting mine rebuilt with a longer 4th and 5th.
Title: Re: Gearbox
Post by: Sgt_Lemon on 03 February 2014, 23:13
Your initial post was about the car feeling sluggish and the gears too long, the goal being more acceleration. Now we have gone the other way to make a more fuel efficient and motorway friendly top end.
Title: Re: Gearbox
Post by: Mcwill on 03 February 2014, 23:26
Haha I no, I can't make up my mind  :laugh:
It dose feel faster now the engine is run in a bit.

Title: Re: Gearbox
Post by: Gambit on 05 February 2014, 16:07
so now that you know its a AUG box :) you can use the webpage http://www.scirocco.org/gears/ to calculate different speeds/rpm's for gear ratio's until you find one that suits! id just stick a longer 5th in it, and be done with it!

Sorry to go over something that has been gone over 1000 times before but I'm confused :undecided: don't take much.
After doing lots of research I had came to the conclusion that I needed/wanted a 02a box with code cdm or ata for my mk2 abf, But after talking to topgear/gearbox rebuilders they have told me its a total different box?
Help!  :sad:

Title: Re: Gearbox
Post by: Mcwill on 07 April 2014, 20:07
No aug is the code on the box I have just blown up, it's the 8v mk2 box
Title: Re: Gearbox
Post by: Gambit on 07 April 2014, 21:51
02o box is rod selector. 02a cable change box. So if you had an aug then you would need to change the whole gear shift mechanism to run a 02a
Title: Re: Gearbox
Post by: Mcwill on 07 April 2014, 22:12
Yeah that was the plan gambit.
So I was rite the 02a will fit the abf
Title: Re: Gearbox
Post by: Gambit on 07 April 2014, 22:22
Yes it will physically fit the block, you just need associated parts to go with it like clutch & shifter assembly etc

Also where is the best place to get lightend and balanced flywheel and is it an abf one I need?

And last thing I read somewhere that the luk vr6 clutch from gsf is the one to use, is this correct.

Title: Re: Gearbox

Its a longer box. At 5k rpm in 5th youll be doing 120mph as opposed to about 105mph in your old aug box.
