Any time you add significantly more power than the car came with from the factory, you can double that cost to balance it, easily. New suspension, brakes, driveline bits, or replacements when they go, etc. etc. etc. etc. etc.

Buying the car you want is easier/cheaper in the long run than building the one you want from an existing car that wasn't designed to be what you want in the first place.
