I've heard that turbo'ing a CVT is dangerous and risky especially if you really want to get a lot of power from it and if the CVT does break after the turbo, I imagine it would not be covered by warranty and would be again pretty pricey, on top of the actual turbo system and tuning which is also expensive depending on the tuning shop you choose and how properly they do it.
regarding the grille, I haven't seen many aftermarket grilles that actually look good other than the one on my stillen front fascia but that's molded into the bumper so I can't really do anything about that, and on the stock bumper, my favorite would be the c-mod grille.
My Stillen bumper has heavy damage so I'm planning on getting a new OEM bumper with the c-mod grille and doing a white/black two tone paint job. From a couple of body shops I've asked around, getting my bumper professionally painted to match my car would cost $250-300 on average. Hope that helps give you a scale on how much the whole thing might cost. good luck
