Wow super cool, I just saw your RS6 6 speed build thread on Audizine, looks like you're persistent & mean business! So I understand correctly you are planning on installing the RS6 BCY mated up to very large turbos into the C4 Avant shell? If I understand correctly that sounds awesome I've always liked the C4 platform & keep an eye open for them for sale online .

I do agree w/ nubcake on the stealth mode benefit of not having the turbo popping out of the hood tho, can you engineer it to blow out the bottom or even sides and make modifications to fenders if necessary?

Finally once you pull it off & I have full faith invested in you, can you build this one for me using a BCY core?
