En tysk som heter Juergen (heter Stichl på forumet) har lyckats med konststycket att para ihop fyrhjulsdriften från en Alfa 155 Q4 med en Coupe 20VT..
Undrar vad han skulle sälja den för...
------------
I did a 4x4 conversion with a 20VT.
It is not as heavy as many people think!
Biggest problem is:
- the oil sump... you need to modify the original oil sump - we cut away some parts from the original one and welded it again... this was a sh... job!
- a tank: you have to cut away the spare tyre boot. I installed a selfmade tank - but there are some older rare Delta 2 with a tank, which matches to the coupe (you need one which can be placed after rear axle).
- a new downpipe + exhaust - I welded a custom part.
The other parts are almost "plug in"
The engine moves about 1,25cm towards the right (then there is no space between the frame carrier and engine any more)...
The original engine mounts will do this little way.
Then you have to use the Integrale gearbox (fits perfectly to the engine) with the tranfer box and the original transfer box mount from the Dedra/Q4
To get the gearbox fitted you will have to use the gear box cover + mount from the 5-gear 20VT.
Some minor modifications have to be done to get all fitted...but not great...you need a good mechanic...
The complete rear axle will fit per drag and drop... you will need spacers, because the rear axle of 155 Q4 / Dedra is smaller than Fiat Coupe.
You can use a Dedra Integrale (advantage: longer gear ratio - the Alfa Q4 gear ratio is too short) or a Alfa 155Q4 as "donor"-car
advantage Q4:
- a real Torsen differential as rear axle
- power 47% in the front / 53% in the rear towards 54%/46% (Dedra)
These cars become broken very often meanwhile - you get the parts, you will need, for a small amount...
I also realized, that with some bigger modifications it should be possible to use the 6th gear box for the 4x4 - the 6th gear box includes an adaptor for the 4x4 main differential.
Another number of crown gear teeth is the only problem...
