Does it come with a S/C case? If not you will need to completely block off the pcv valve and run some sort of a breather system for the crank case. Also does it include the turbo oiling kit, you will need one of those. Also a way to block the egr off if you don't already. You may want to check into what it takes to bolt a CT down pipe to your stock exhaust, I know the Z7 kit needs a TOG's down pipe. You will need to beable to tune your car whether you own a tuner or a friend does. It better to tune it youself rather than buying a pcm with a tune on it already. I am not sure if the A2A piping will fit in a monte or not, maybe someone else will chime in. That is all I can think of for now.
