A friend of mine is on the verge of picking up a mint 93 B4 fwd Avant.
It currenlty has an ACE 2.0L 16v engine as fitted by the factory, but what he wants to do is convert it to an 1Z diesel engine and gerabox from a dead body’ied Audi 80.
He has a daily work commute of 50 miles per day.
1. What’s involved in fitting it as he will have the two cars side by side ?
2. Engine mounts the same ?
3. Driveshaft and brakes should not be an issue.
4. Change the fule tank from petrol to the diesel tank ?
5. Fuel lines ?
6. Fuel pumps ?
7. Is the breather bypass worth the effort ?
8. How well / effectively / easily can it be chipped ?
9. What’s involved / or do you change the pedal box to accommodate the fly by wire throttle ?
10. Different turbo possible ?
11. He also has a spare engine from another dead car which could be rebuilt, but are the average things he would need to budget for changing, and the approximate total cost ? he would be doing all the work himself, so it is just parts.
12. Whilst I am aware that he could buy an already oem made 1Z diesel fwd B4 Avant, he con’t find one in his preferred colour and this car / nee body that he is about to get is mint on every front including the colour, it has newly refurb’ed 10 spoke 15” wheels and new branded tyres. Hence the above queries.
13. Will he have to swop out the pedal box ?
If so, will he have to remove the dash or it a case of it makes the pedal box swop out easier, but it is not essential ?
The second option is which would be more difficult, but would lead to a better end result which is the installation of a later 4 cylinder 1.9L engine and gearbox engine and box from B5 A4 TDI. This could be chipped more and is a better more modern engine, turbo and gearbox ( 6 speed ? ).
14. What’s involved with such a conversion and has anyone got a link to thread where someone has done it before ?
15. Unfortunately a 2.5L 5 cylinder diesel conversion in not within his grasp, based on costs, and possible additional level of difficulty.
16. Like a lot of my posts, they’re wordy and have lots of questions, ...
...
, but thanks in advance for any assistance that can be offered to allow my friend make an accurate decision on how best to proceed given his options.
