I'm thinking of installing a twin turbo kit to my C4S. I have a 3.8L NA. Has anyone attempted this? If so, is there anything you can share?

 

With what you will likely spend getting this right you'd probably be better off just selling car and buying a 997 Turbo. Also the fact that a car like that with an aftermarket turbo kit would likely be hard to sell down the road. Oh, no Mezger either. Not a good idea.
