Just a option for someone who is looking to do what you want to do. I have a nearly complete boondocker kit, only a few parts would be needed for a better then good deal. Pm me for info
I have built my own turbo kit on my 05 m7, still working out the bugs. I'll try to let you know how it turns out. way more time and money than expected so far. but if it works I will have way less $ in it than buying a bd kit.
