Glad you've got hold of an A8. They're still very handsome-looking cars. Unfortunately I don't think we got a diesel of any kind in that generation in the UK, and an A6 of similar age doesn't appeal quite as much.

Well my 2.5 fuel pump circuit board already broke so the engine swap will begin ASAP. Cost to repair the pump about 1000Ä. Tried already to replace the transistor and that did not work...

The CitroŽn C5 wheels were 15" and ~4kg, I have those on my Peugeot for summer.
Ultralight 15" wheels for CitroŽn/Peugeot owners

I believe that there may also be ligtweight 16's for the CitroŽn C3, but I haven't investigated it.

I found the post with the list and answered myself about what light wheels to put in a vw golf mkiv platforma car.
I did already some theoretical calculations about how much improvements in acceleration I will get and it seems that aerodynamics is the way to go. weight reduction seems to be better in traction on bumpy road and in ride confort other to affect fuel consumption (we are talking about not very heavy tyre+wheels with very big inertial moment). maybe important in city, drag racing and racing.

do you measured any noticebale decrease in fuel consumption between lightwheels and stock on road?

Project is still alive and well.

At the moment weigth reduction BOM shows 1448 kg so already weigth has dropped nicely.

Lupo engine is at place and work continues with exhaust piping, altenator belt to add air condiotioner and power steering unit. Also starter motor need to be installed.

Hopefully this beast will be alive during next weekend as electrical wiring process begins


More pictures again here

So power steering will be belt-driven? Why not use electric PS?

Yes belt driven at first stage anyway. First target is to get car on the road with that 1.2 TDI. There are million mods long list what will be done and tested...

I have made some calculations based and cd targets and BSFC map.

Looking good I dont need very low drag to reach that 3 liter target that means I migth not even have to make a "boattail" to the car to get there.

Is the old 2.5 TDI a V6? The V6 2.5 TDI engine is what a local mechanic considers to be a nightmare to work on. As soon as you fix something, something else doesn't work. Change a valve cover gasket, and it might leak after two weaks, even if he uses a Victor Reinz gasket. He is convinced the French designed it, and he hates working on French cars. I don't really have anything against the French, but their cars could be easier to work on.

On the bright side, he says that they run great and are a good engine until the problems start.

Could you take a better picture of the engine bay? I'd love to see how small the 1.2 tdi engine looks in that big car. :-D

I'd also love to see a peek of your BOM.

Cant wait for the car to hit the streets. Your background research seems thorough.
