There is an article in this months Total BMW mag in the questions and answers section about building a 2.7/2.8 and what is needed. HTH

the compression ratio is quite high when using the pre facelift pistons at around 10.8-1, but with the overlap of the cam, it should come down a bit.

you could run it on super unleaded. your not building it to be economical are you
