I guess whatever early work was done on the Eva GT would be transferable to the Aero 8 - the 3 litre petrol turbo engine.
I've got in in 307 bhp form in my quite heavy 535i tourer and it's a great engine in that car with easy torque and a nice wail as the revs rise. But will change the characteristics of the Aero 6 (!) quite a lot and is a good deal longer too.
Easier to get more power out of too - witness the latest M3/M4 and others.
This is what I was expecting anyway - as we knew the engines were running out and no more are available...
