apart from needing about 48mm minimum for the waste gate as you wanna use a small ex-housing. The turbo and NA bottom ends are as good as each other BUT, the A8 pistons are dished and the A6 aren't therefore it will be cheaper to get a standard head gasket and build up the A8 route. fuel and turbo choice with that cam should be singing sweet at 400HP on 18psi at a wild guess. haven't tuned that exact combo before but I calculate that 1000cc injectors would do the trick. naturally ensure the fuel supply and return is sufficent.
