Got it going Thursday night and took it to work Friday.
Apart from a couple of teething problems its been good so far.
It's pretty much the same as before, but smoother and has more power at the top of the rpm range.
Once I happy with it I will swap in the bv50, hehe

Also, the cold idle is beautiful and smooth.

So a bit of an update.
I took the car up the coast over the weekend - it performed flawlessly and I was all back in love with it.
Yesterday morning I jumped in and left for work. After about 5 minutes the car starter to idle really weird (high, around 1300rpm) and I get esp, abs lights on the dash. Gear changes are all rough and tumble.
So I took the golf to work and scanned for codes after I got home. Got 2 error codes apiece on abs and trans control module, plus 3 on the engine including a persistent coolant temp sensor error.

I changed the coolant temp sensor tonight and bingo, car runs perfect again.

Fancy that a coolant temp sensor fault could cause all that woe!

That's why my MK1 is getting twin carbies. The only engine electrics will be in the dizzy.

As much as I'd love to fit a modern turbo diesel I hate not knowing what to fix when the engine has a cough.

Cheers

It's not a huge deal - didn't take long to diagnose, but its surprising the flow on effect from just the one failure.

So I'm now very happy with the Audi once again. Running very well and today I've ordered new engine mounts and front driveshafts to freshen up the driveline (split CV boots and engine mount fault codes popping up recently).
I have also begun a little work on the turbo conversion bits and bobs, sorting out some small issues. One of them was a bit of a leak between my adapter and the new turbo, which is really down to me only half doing the job in the first place -hehee.
I'm not using gaskets between the manifold, adapter and turbo. This means the mating surfaces need to be nice and flat.
To acheive this, I'll be wet sanding the adapter on a bit of granite bench top like so:
You can see the leaky bit, just on the top left edge of the triangle. Lots more sanding required yet. Unfortunately stainless takes forever to sand like this.
