I am thinking seriously about the same mod in the coming year or so. My only concern I guess would be how it will impact the lower engine mounts on an older HO engine. While the compression is strong, it is light about 10pds at number three hole on a fresh gasket and that is probably the way it is going to stay until I blow the engine or turbo. Thus, while I would dearly like to lose the drivetrain weight, I am worried that the vibration will start consumming the oil mounts *even faster* than on my last one. Did you go for the pucks or do you still have factory lower mounts and are you 5 speed?
