If the new 5.7L stroker has the same principle of E39 M5 S3, and I assume it is. Dinan make an engine not just for performance, but also comfort and stock feeling, if u know what I mean. I have a chance to ride in E39 M5 S3 at All German Auto and driven by Martin. It was a blast, not just in term of power, but comfort as well. The car feel like stock, smooth riding and luxury sedan, but when he punch her through weavy back road in Escondido, CA, the handling/power are amazing, they balance very well between power/comfort. Gustav and many others have ridden in that S3, and I'm sure everyone would agree to balance between power and comfort.
So, if money is no issue and you can justify to spend close to $50k, I would say go for it. People might argue that u can buy z06 if u want power, or amount of money spend on Dinan motor could get you a 997TT, 997GT3. But if you primary goal is super luxury power in SEDAN form, even with $50k extra, no one will even come close YET.
