The BMW 2.8 (and 3.2) engines still use a cast iron block, where the Boxster uses a linerless high silcon aluminum block. Of course that's the same technology Chevrolet used in the Corvair, in the '60's.
The Corvair didn't have a conventional block. The crankcase was an aluminum alloy but the cylinders were individual barrels made from (I think) cast steel and sandwiched between the case and heads just like on the air cooled VW engine that GM copied.
