Hi OzAudi,

I am looking to do a full Engine conversion.

Option A: 4,163 cc V8 (CAUA) to go with my existing 6SP Manual Transmission
Option B:
4,163 cc V8 (CFS) to go with my existing 6SP Manual Transmission (upgraded clutch) or 7Sp DSG out of an RS4.

I have been reaching out to people who have done this (found on youtube). Unfortunately, I would have had better luck squeezing blood out of stone.
Understandably, the S5 is the closet doner for this. But, I do much rather the RS4/5 CFS engine.

You may ask, Why? Well, Why not.

So, if anyone has attempted this successfully or knows someone who has, I would be love to get in touch.

Many thanks in advance.
