BMW gearbox - anyone done this conversion?

Ive searched but only found odd conversion here and there.

 

Im currently W58 na/t with 8.8.1 compression ratio drop and can't justify a v160/161 conversion, but the bmw getrag conversion looks to be a better and more cost effective version of a built R154? (got my own garage so labour times isn't a concern)

 

Im getting my car dyno'd again at the end of the month once my alloys are back from refurbishment and im thinking i should be around 420ibft mark (tbc holset hx35 at 18psi) so i know my w58 is on borrowed time hence i have another boost set at 12psi for when i have passengers/loaded up to reduce driveline strain

 

so Just wondering who has first hand experience in this conversion, if so what box did you opt for and any issues you came across?
