uRS6+ Build

Custom Tubular headers with a top mounted Precision 6766 Turbo

If you want the thing to be remotely reliable - do yourself a favor and pick up a set of S6/S8/A8 NA exhast manifolds and just elbow off of that. Custom made tubular stuff tends to crack really quickly and doesn't give any real benefit.

For a journal bearing 6766, will an oil reducer be necessary?

No, if you feed with AN3 from a stock banjo. Maybe even AN4 can work as is.

I plan on having the power delivery coming on smoothly on the right end of the power curve to help prevent not throwing a rod. Feedback is greatly appreciated.

Stock rods live just fine at 25+ psi on small peaky hybrids. You'll be fine with any power delivery with a big turbo (it's naturally smoother acting), as long as it's properly tuned (and fueled!) and doesn't knock. Talking gasoline ofc.

Twin Walbro 450 Fuel Pumps

Twins = overkill, unless you go E85.

yes, the turbo will be sticking out of the hood...

I don't like this.
Comes down to personal preference ofc, and you're free to do whatever as it's your car. But to me the whole idea of such build is to have a "sleeper", that can surprise everyone with sudden 700+hp.

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?
