Title: Mk2 Gearboxes
Post by: promethius7 on 23 March 2009, 20:05
Does anyone know if theres a stronger gearbox to fit a mk2 16v with as little mods as possable?

I suppose it depends on what you mean by stronger? Are you planning on modding the 16v?

Many of the Mk3 boxes will fit - they are newer but you'll have to check the code on the bell housing to get one with the same/similar ratios.

I'm sure someone will give you a difinitive  answer as to whethre they are stronger....?

I've got a Golf3 16V cable-change gearbox, with the complete shift mechanism here.  You'd need to run a Seat Cordoba O/S driveshaft and a Seat cable clutch, but that should see you well past 200bhp without batting an eyelid.

have been looking at this recently. the golf 3 16v box is too tall compared to the mk2 one. for a standard cable change gearbox the corrado 1.8 16v is the best ratio'ed for a mk2 16v. after that you have to piss about with final drives

Hi
Do you know what code the corrado gearbox is. Cheers

its AGC.

heres the theoretical speeds with 195/50/15

           1     2      3       4       5
02o 2y   37     61     90     115     143
02a agc 32     57       90     124     152
02a cda  39   67     99     126     155

neither are ideal really, what im gonna go for eventually is the cda (mk3 16v) with a 4.2 fd to make

            34      58     86   110   136

I've been thinking about this too.. Surely a 16v box in good order can handle 200bhp? The ratio's are perfect it seems??
My Mk2 16v gearbox is a little slack now, so would it be cost effective to get a recon box & fit that? Does anyone know where to get one?
The engine is going to be replaced with a 2ltr, gas flowed 16v head & Piper cams, so I'm hoping the box will take it through a HD clutch???

16v boxes are stronger than 8v boxes anyway, so i cant see why a standard one wont see 200bhp.

diff rivets are still the same and they go bang first,       16v box with a bolted diff is tougher than 8v box with bolted diff.   

a ported and cammed valver 2.0 will eat diff rivets if you drive it like it should be driven

ooops- i forgot about those dreaded rivets!

on fwd they just bite 50 bhp later than on syncros  :sad:

internally 020 boxes are all the same in terms of strength, if anything 16v is a bit stronger due to larger input shaft but its hard to snap one, tho danny managed it :grin:

all the gears & diff etc are the same strengths though, if you want piece of mind an 02a box with bolt kit is the way forward.

Well if you gonna go 2.0 with ported and polished head i would do something with gearbox as i have a 1.9 8v gti engineering mk2 golf and i have just gone through my fifth gearbox. So now have got another gearbox coming.
