Your flywheel is too small in diameter to accept 240mm clutch.
If you use B4 2.0 flywheel you have space for the 240mm clutch.
You have to resurface flywheel for 240mm clutch and rebore flywheel to accept 5cyl pressure plate.
Your can't use B2 4cyl starter in combination with B4 2.0 flywheel because it will not clear the flywheel.

So, the biggest problem is your gearbox. You could cut and weld the bellhousing of it and possibly work something out. But... if your gearbox fails and it definitely will, you will have to do that work again and again.

Isn't the B2 1.8 DZ quattro box the same as the 2.2 versions?
When I had a 1.8 DZ quattro the tunnel/gearbox area and floor area near the pedals was very different ( wider/bigger - less foot room) than my 80Sport

Is this for a coupe quattro 1.8 or a B2 80 quattro?

Looking at the Sachs catalogue a 1985 Audi could have a 200, a 210 or a 228mm clutch.

There is also two different size gearbox input shafts. One much smaller than the other. In the VW world the larger shaft was introduced on the 16v mk2 golf in 1986 with the 020 gearbox with a 210mm clutch. When VW adopted the 02A gearbox they used the larger shaft across the range with a 228mm clutch.

So, basically, you need more details about your current install in order to get the answer you need. There is a chance that your current gearbox can only take the 210mm clutch with the small input shaft... in that case your options are limited (this is the same as when you fit a 1.8t into a mk1 gearbox with a 020 gearbox).. you're looking at Helix or Sachs Sporting.

If your gearbox is later, you may well have a 228mm clutch with larger input shaft in which case the G60 clutch plate and flywheel with a VR6 pressure plate should be spot on.

So far I've noticed that there are two input shaft sizes for audi gearboxes - thin - found in B2 and C3 gearboxes, and thick, found everywhere else.

If you use something newer like 01A, 01E then options are limitless.

01A won't work - ok, it will - it will blow out gears on the pavement

Which will probably be the same as with VW:

diameter 20.6mm with 24 splines (180mm, 190mm, 200mm & 210mm clutches)

diameter 22.2mm with 28 splines (210mm, 228mm, 240mm and larger clutches)

There's also the 23.8mm with 23 splines used on 1.8 20v Turbo A4's I believe.. but thats probably not relevent in this discussion..

wow thats an amazing response with some very useful information. Why anyone couldn't just say this in the first place....

I ran a search on ECP site with my reg and it said I have a 228mm diameter & 230mm plate, so will measure it up tomorrow and have a butchers properly. Hopefully it is the larger type and less fannying around.

Cos I wasn't online

So you have a 228mm with the really big 23 spline.. That's good news

UH gearbox have 18,3x20,4--24N

If it helps any, when I out a 1.8t into my b3 90q I used the original dual mass flywheel and clutch from the a4 donor car. Worked a treat but couldn't cope with the abuse all the time. I tried a paddle clutch designed for a golf vr6 and the spline on the gearbox was too big so the clutch would not work. In the end I had a 240mm spec clutch fitted to a 1.9tdi flywheel after having holes redrilled for the bigger pressure plate.
