Byeyou here had a 2.8 from a 97 3 series fit in his ride, getting better torque with his touring. So I'm just curious as to what other newer BMW engine you could fit in there, and how recent that could go up to. I also remember a V12 being fit into another touring from a 750 donor. That was impressive.
As my e34 has just reached 410 000 kms, the engine runs still great, but not fabulous of course. I might chip it, but I'm not convinced it would be a good idea.
So I'm just dreaming here because I'm not close to being able to afford an engine swap yet. I'm just fascinated by the possibilities.
