The upgrades are good but you can add more of you wanted like for example in pixel car racer you can either have supercharger or turbo but I've seen proof that you can have both a supercharger and twin turbo at the same time but to make thing more insane I've seen a video of a dude having a four cylinder engine equipped with four turbos that one turbo per piston just something I figured I'd point out and yes please add more garage space
