I am new to the 7. I have a 3rd gen and understand what is involved in going to a 3 rotor, but I ask you this. What is the price involved for the 4 rotor? Is there a site that I might could gauk at? I'm curious as to what the price actually is. Thanks for the help.

There isn't really "a price"
It's a 100% custom job (that includes making the engine). I'm not even sure if a street legal FD has ever had one in it.

 

It will radically change the weight distribution of the car and is not worth it all. You can already get an easy 500 rwhp out of a 20B as it is.

If you feel like spending $100k, go for it. IMO, an LS-1 conversion would make a hell of a lot more sense....
