If I had the stones and spare money hiding in my couch, I would jump on it. Fact is, it takes more money to increase power on an NA vehicle over a FI one. Most likely someone investing money in these cams, valvetrain and pistons will most likely have all the Bolt on's already on the car. And just an educated guess, I would say pushing 400hp from a NA Z would be more impressive than a 500whp turbo kit. It may not be faster, but I'm sure it will sound like it
