Out of curiosity do you know if the motor you are using bolts up to the S4 B6 gearbox ?
Great work by the way

The engine I'm using does bolt up to the B6 S4 (BBK) gearbox.

Update: 10th January, 2016.
A satisfying day.
I installed the Milltek de-cats yesterday, so I was able to fit the S4 front axles. o2 sensors fitted too.
As I posted previously, the angle of the aluminium radiator pipes was wrong, and will need addressing. I have cut the inlet and outlet pipes at the right angle to be welded to the radiator. The modified 4 cylinder front crossmember also needs to be welded (boxing the notch). I've loaded them into my B5 2.5 TDI V6 Quattro's trunk, they'll be dropped off at the shop tomorrow.
Aircon hard pipes to compressor have been connected, with new O-rings.
For an OEM airbox solution, I had purchased 2 to choose from - C5 S6 and B6 S4.
The S6 airbox can be used, but I'll mean either running the S6's throttle body intake, or cutting the D3 A8's intake pipe down. I'm not keen on treading this path.
The B6 S4 airbox is better suited to the BFM engine and throttle body intake, which is what I ended up using. I need to cut off the lower mounting pegs, and make my own to fit the rubber bungs in the B5's frame rails.
My motorsport trans mounts are not right - they are too thick, meaning the 01E's shift linkage it really close to the transmission tunnel roof. I have spoken to the supplier, and they are sending me another set. The ones I have are okay for an 01A, where the shift linkage goes into the transmission tail, they are sending me a set that will work with the 01E. In the interim, I'm using the stock 30V mounts.
Some pictures of current progress.
Pictures showing B6 S4 airbox. Ignore the spiffy MAF connection, I haven't fitted a worm clip, as the airbox is coming back out, so I can install the SAI pump below the frame rail:

Update: 24th January, 2016.
After 3 tries, my aluminium radiator is finally right. The inlet and outlet pipes have been modified to my satisfaction, and now clear the alternator, and timing belt cover.
The 1.8T crossmember I had already notched to clear the aircon compressor, but it just needed to be welded. That has also been done, I painted it and fitted it. Perfect fit. I have trial fitted the radiator, condenser and front bumper. I still have space for a pair of 10" puller fans, which I'm happy with. I will run an additional B5 S4 pusher fan on the condenser side.
I'm waiting for my 4.11:1 rear differential. I need to fit my C5 RS6 steering rack to vane pump high-pressure line, plumb in the engine and transmission oil coolers, plumb in the short feed line from the power steering resovoir to vane pump, reinforce the top of the lock carrier with an angled steel bar.
I haven't ordered my puller fans yet, this I will do sometime in the week. Once the pullers are fitted, I can bolt on the lock carrier, radiator and condenser for good.
Some pictures. Note the notched B5 4 cylinder lower crossmember, and more than adequate clearance between the notched area and compressor pulley:

It's an open differential.unstable load wrote:Looks a lot like the P6 Rover diff.stevieturbo wrote:That must be the longest diff unit I've ever seen ! lol
Has me thinking about a transplant for mine.... is it LSD, Nollywood?

Update: 06th February, 2016:
I have finally pulled my DAJ (3.89:1) rear differential, and installed the B5 RS4 replacement, DQA (4.11:1). So the rear of the propshaft is bolted up. At the same time, I discovered the source of a persistent grating noise, which has been speed-related. The previous owner told me the noise had been present for almost a year before I purchased the car, and he'd had both rear wheel bearings replaced in an attempt to get rid of it.
The right hand output shaft seal was pretty much non-existent, with drips of oil sitting on the axle shaft flange. I drained the oil, as I had to swap over the output flanges - replace the B5 RS4 108mm ones with the B5 A4Q 100mm items. I got just over a litre of dead oil, with minute steel filings. The oil was completely black.
Next is to install the middle and rear section of the exhaust.
