103 engine 3 litre capacity increases?

[prwales]

what is possible with this engine? Can a crank from a 3.2 104 engine be fitted are there other options? I think Brabus managed to expand it to 3.6 and even 4 litres but how? Anyone know?

No doubt Brabus bored it out, changed the crank conrods and pistons, ported and flowed the head and fitted high lift cams and strenghtend and balanced everything. then they tuned it to perfection.. I doubt if they would even let you see the blueprint for the engine...but you could try and fit the 3.2 crank..

apparantly they used the crank from a 350 diesel plus some re-boring
