Title: Mk2, Mk3 subframe, Mk4 AGU - Does it work?
Post by: Dave_IOW on 11 June 2012, 15:06
According to this, not.

http://www.clubgti.com/showthread.php?243755-Mk3-subframe-1-8T

Has anyone on here got a mk2, with a mk3 subframe with a 1.8t in?

Or am I going to have to get a mk2 subframe, reason I didn't use mine is it's a 1.3 and I believe I need a different one to bolt 1.8t onto.

1.3 is different to 1.6 and 1.8 which is why you needed a different subframe.

We'll soon find out if it works when the motor and gearbox are mocked up on the subframe.  :cool:

Always interesting to hear if someone else has followed the same route though  :smiley:

Let's hope so too as I plan on fitting my mk3 diesel subframe + rack widetrack etc with an agu in the mk2 in the not too distant future.. Fitted the mk2 16v subframe rack etc when I went from 1.3, if I recall it looked the same, I just dropped them and swapped them for ease...

Out of interest, why a diesel subframe? Or was that just what you could get your hands on?

Mines mk2 on mk3 subframe with an agu bolted in dave. Fits up nicely.

we did a MK2 with a MK3 subframe, and a AGU with a CDA gearbox (mk3 ABF)

perfect fit, no issues

Am using abf mounts on mine. And an agu gearbox with a modified mk2 golf mount. Fits nice n snugg

Using AGU shafts aswell then, or 16v ones?

Agu but its not the easiest to get the drivers side to fit

Do tell, got all this to look forward too  :smiley:

Well. I'm wide tracked and I had to take the hub off and 2 of us to push it all back together. It may be easier on a ramp as the antirollbar will relax as both fronts are off the ground. I tried findin bigger wishbones just so that it would make it easier but didn't get any direct answers on what would fit. Passenger side slides in fine though.

Yeah I'm using diesel as got parts free off brothers mk3 before it went to scrap. Also its 4 bolt not 5 bolt like gti. I've already got 02a box + abf in the kr 16v frame, going to drop the lot, mate the agu to the 02a,drop both into mk3 frame using mk3 shafts etc and offer it up to the car, then remove diesel hubs for gti hubs and g60 brakes+ carriers etc. I defo need to use the same gearbox mount and bracket, starter etc,I guess that means I use 02a front bracket and mount, its just the rear bracket/mount combo I need to research. Will be using ford focus short 22mm m/c as well

Just confirm what you're using there.  I suspect you have a driveshaft from a car with a rod-change gearbox .  These are longer because the 020 gearbox is narrower than the 02A, thus the driver's shaft is about 10-15mm longer. 

I would expect what you've done is pushed both CVs in to their limit.  This is likely to give you some REALLY odd handling issues and the end of the driveshaft will batter the hell out of the flange when you corner.

In my view you need 02A gearbox and the front mount off it, plus driver's side shaft off the same.  The passenger side shaft is the same for 020 and 02A.

The question here is whether the rear engine mount combination has a different height G3 vs G2. They are totally different arrangements: the G3 is a tower, the G2 mount has two brackets either side of the mount, at 45 degrees.  The G2 'G60' mount also bolts up with three bolts on top and the G3 has a single bolt. The rear bracket on the gearbox is the same through all, I think.

If I'm honest I would be surprised if there was a height difference in the rear mounts, UNLESS there is a difference in the gearbox rear mount.

Already said that to him DH if it drives like a crab go back and change the flange and shafts!

Yeah I'm using 020 16v shafts on my 02a box at the mo, and will hopefully be able to use the diesel 020 (longer widetrack?) Shafts with the 02a when I come to swap it all over, thing is I've got to change outer cv joint on current shaft, the passenger side one, will I be able to use this shaft with the mk3 subframe etc then if they're the same? (Saves wasting a new joint that'll only be a month or 2 old on removal)

Really? I thought a mk2 subframe was a mk2 subframe, just the bolt on engine mounts that differ

So can you not use mk3 shafts with 02a box in mk2 ?

I believe so.  I'll do a final check when I'm standing over Dave's G2 later in the week, but the 1.3 is *quite* a different unit!

So can you not use mk3 shafts with 02a box in mk2 ?

Well that depends on what shafts and control arms you're talking about.

e.g.
G3 8V = widetrack and 020 gearbox
G3 TDI = narrowtrack and 02A gearbox
G3 16V = widetrack and 02A gearbox

So hopefully you can see each of those will probably have a different combination of shafts on it.

So if you're running narrow track with 02A gearbox you would need G3 TDI shafts to suit.

If you're running widetrack with 02A gearbox you would need G3 16V shafts to suit.

Golf3 shafts covers a multitude of different combinations!

What would the 1.9d (non turbo) mk3 have then? It had an 020 rod change box, and I've kept the frame under the impression the driveshafts and wishbones are longer etc?
Title: Re: Mk2, Mk3 subframe, Mk4 AGU - Does it work?
Post by: Diamond Hell on 13 June 2012, 13:32
Narrow-track 020, so the same shafts as a G2 GTI and 16V, *probably* with the 100mm inner CVs.

Post by: mk2bal on 13 June 2012, 16:41
So a mk3 diesel non turbo is no different to a 8v/16v mk2 in driveshaft lengths/wishbones/track rods?

Pressumably not  :huh:

Think i'm going 02J now anyway, will have a look tomorrow and see what's going on.

Gutted if that is the case, I assumed all mk3's were widetrack, and the di and tdi's were the ones to have as they're 4 bolt..

Got 02a fitted and tdi hubs and 256mm setup at the moment.. but only have 16v shafts or mk2 8v shafts time to go hunting lol i want some with preferably dead CV's as i have a full set of new ones :)

So, just to round this out.  Here's the 1.3 subframe that's currently in Dave's Golf:

(http://img.photobucket.com/albums/v627/diamondhell/2012-06-13162441.jpg)

and here's the G3 subframe that he has:

(http://img.photobucket.com/albums/v627/diamondhell/2012-06-13162703.jpg)

Taking the measuring stick out it looks like the G3 mount finishes at 200mm from the top of the flat bit of the frame.  Measuring the G2 subframe in the same way gives 180mm height.

I think we'll try the 1.8T on the G3 subframe and see how it fits.  If there are issues we'll swap it out for the G2 frame and see if there's any difference.

Don't Danny, just don't  :grin:

Mk2 subframe is out now though, still unsure on what combination of mounts and brackets to use..
