A word of warning: re-think your oil pump situation.
What happened to that engine that caused the rebuild was the oil pump shaft failed. It will happen again unless you go with the BMW Motorsport solution, or dry sump. I've tried the VAC piece, and I know lots of Koni challenge engines that have tried it....and it fails.
If you want to trust the VAC pieces, get it in writing from Tony that VAC will pay for the rebuild when the oil pump shaft fails/sprocket spins off.
I followed the installation directions to a "T", and I know others that have as well and ended up with the same results....the oil pump shaft nut comes loose, and eventually the oscillation of the sprocket kills the shaft. Welding the nut on is a short term solution that eventually ends in the same place.
All the rest of your parts list is great!
