To make this gearbox fit on audi 80 quattro B2 we shortened the prop-shaft by ~30mm

[Error404]

I wouldn't use a single piece prop it will either weigh a ton or be really expensive, or both! You only need to shorten and balance the front section. Not sure on the length of the 016 but for reference the OA3 is 28mm longer than the 01E

from page 6 of this thread

Cool. That 30mm was a good guess then lol

I got the alternator back overhauled with new slip rings and regulator with brushes.

I had a go at tig welding the alloy bushes I had made up into the cast alloy bracket for the alternator. Its my first time alloy welding and it seems my kit can't do the current I need for heavy alloy parts. I got a nice enough weld at the outside of the bracket but in near the base coudnt get enough heat into it to make a nice weld puddle.



I'm using a 350 amp murex boc arc welder as an ac power source feeding a boc hf 450 amp box. The power ratings are on 3 phase so my issue is that at single phase the 350 amp murex is only doing 125 ish amps. By the time it's out of the hf box I'm little over 100 amps I suppose.

I later tried some 2mm plate and it was fine. Man alloy conducts heat and needs amps! That same murex can glow a 4mm arc rod no problems.

Urs4 prop almost fits. Just needs a 70mm spacer made up.

Fitted a new prop bearing

Will give that a go next time James cheers.

Driver side drive shaft fitted with spacer with notches machined on it for Speedo sensor as per Alex's design.



Tried looking at down pipes. 3 inch is easy.



3 inch with a 2 inch wastgate tube is going to be tight.



4 inch is daft. Not going to ever fit.

Odd, I needed the spacer on the passenger side

[quattro-nick]

i orderd pieces to make a 3.5 inch rvs exhaust for my car

Ok I must check for plunge in each shaft. Can you feel much movement in yours when fitted?

Do you plan on connecting your wastgate back into the 3.5 inch down pipe?

[quattro-nick]

yes, that is just the easiest way
the picture is from my 3 inch downpipe now
