Unfortunately those motors never came into the states . I wish they did, I'd put one in my mini in a heart beat. At any rate, they were named (internally by GM) as the "ecotec", though this motor came before the "US" Ecotec. IIRC, they're completely separate engines and designs (I like the Iron block euro motor better) and during the CX reign in europe when these motors were fighting with the big boys like the Cossie motors and the array of German DTM derivied monsters, we were stuck with the ol' quad 4 and it's deravitives. The new Ecotec is company wide and has a new head design along with an Alloy block and (unfortunately) some accountant decided they needed to lop off 4 of the 8 counterweights on their forged LSJ crankshaft.
Either motor is amazing really, in the pro FWD classes of drag racing, while most motors are afforded a max displacement of 2.8L (The Toyota tacoma 2.7 is huge in this class), the Ecotec was capped at (I believe) 2.2L, maybe even 2.0L and they still consistently made the finals.
