As above really geezer on E36coupe forum reckons it does.
Is he right or is a

coming his way?
Right confused myself here.
This is what he said.
The trouble with this engine is that the bore is maxxed out pretty much, look at the increase between 3.0 and 3.2, it's all in the stroke. That's also the reason the compression ratio goes up, the cylinder chamber volumes are the same. If you look at this engine with the head removed there's a tiny gap between each piston.
So any increase in capacity will come from an even futher increase in stroke that wouldn't neccessarily be the right thing. Also the compression ratio would need adjusting etc. etc.
