Audi 5000 Diesel conversion

[John Larson]

You asked:
"Can anyone confirm the following: ?

1) I have been told that you don't need a computer for the diesel.
2) Motor mounts etc. are the same, simply bolt in.
3) The manual transmission from the gas TQ bolts to the diesel.

Are there any other problems I should be aware of?"

The gear ratios for a diesel are radically different, as the diesel 
engine doesn't rev anywhere close to the gasoline engines, and the low 
end torque is monstrous.  You're gonna be pushing it really hard just to 
keep up decent freeway speeds.  John
