Maybe but it gives the general idea of what and why you are going this route :approve: really compact lump so air around it should be better to keep it coolish as the heat output is going to be considerably higher with a couple of turbos adding to the oven effect, pop a shelf in and you will be able to roast a chicken for your track day lunch! :rofl: Watercooled turbos are well worth considering to reduce the heat and get it transferred away as well as improve charge density. Keep it going, we all want to see the Renault badged Audi at Goodwood :bow:
Engine, plumbing and bodywork for Goodwood. Then its a case of ECU, engine wiring harness etc etc which I have no idea really. Purely because it will be a case of saving up to give it to someone who knows what they are doing. I have the option of using the stock audi ecu as a stand alone unit but there are so many sensors and i have to run the lousy MAF which adds a heap more plumbing. I want to keep it much more simple.

Two piece engine mounts all done and fitting perfectly on the Jig at last! Pictures above are just one side but both side are pretty much identical. Just need to weld the back plate to the car and give them a lick of paint. They have turned out really well and will make the installation and removal of the motor dead easy now. The only pitfall with them is they weigh quite a bit for what they are (I'm guessing a few kilos) but i can live with that as they are low down and I know they wont ever fail.

Looking good, :approve: just watch the stitch weld for stress cracking though
^^PMSl^^
It has been put on freeze for a while tbh. There is a significant update however which even Mr Williams doesn't know of but I'm not putting up pics yet! I'm just about to buy a new tig welder so I can fabricate alot more without relying on others. First being some small strengthening additions to the shell, the second being an all new manifold setup to convert from twin turbochargers to a single Holset HX52.

C'mon Brett, ya great hairy yettie, can't just go tantalising people........Spill and put up piccies :approve: :approve: .... Need to see some real duck 5h17 welding :rofl: Great fun learning to use a TIG without melting and blowing holes in everything in sight!! :bow:
Sorry about the poor quality pictures. I'll up load some better ones once the motor is detailed and has a few more mods.
Overall I'm very happy so far. Took me and the brother a few hours to wiggle it in place. There seems to be some more room we can steal, around 15-20mm, but a few things around the water pump and a/c pump will need tweaking. If succesful it will allow a completely standard bumper to be used. We are aiming to lower the engine by 30mm too. Driveshaft angles seem ok. Not perfect but much better than I was expecting which hopefully will allow over twice the ammount of torque to go through the c/v's without complaint.
Next step is to fully service the engine and detail it.

So now that the engine is in place, its time to do the driveshafts. This has been the biggest worry for me as they could quite literally make or break the entire project. With the limited space I have and the rule of thumb being to modify the car as little as possible the engine is sitting about 50mm back from its perfect position. 55mm further forward and the driveshafts would be sitting square to the engine and gearbox. Which 1) Puts a lot less stress on the cv joints and 2) Reduces frictional loss through them. As it stands, beggars can't be choosers and I do have a less than perfect angle on them. However the angle is a lot less than I first thought it would be so fingers crossed, I shouldn't have too many issues with them. I have seen high powered Audi's run much worse so Mhhhe! The next job is to see how I'll mate Reno to Audi which I'll investigate once I dig my old shafts out. The likely hood is they will be two or three custom jobbies but if I'm lucky (very) there might be a more straight forward answer.
The pic below is taken just above the left bank turbo looking down and shows the angle I am talking of.

The next small but pretty major issue was that the VW Passat gearbox didn't sit fully home against the Audi S4 motor. Although the bellhousing pattern was perfect it needed a spacer. Luckily these are available from Audi/VW in two sizes. Today I managed to get the correct thickness ready for final fitment. Now I just need some longer dowels and bolts from Audi to finish.
