Thanks for the update williamX5. I wish I could do a 6mt swap on the X5. I currently have no manuals in my life and after spending the weekend driving a buddies 6mt F30 a little bit... I realize how much I miss rowing my own gears.
I think most of what is stopping people from doing this is the lack of trail blazing (you help a lot here), the cost of components necessary, and of course the time to accomplish. Most who would be interested in this are older gents, have kids, house, etc to tend to and so can not afford the time necessary to perform and then troubleshoot a swap like this. The guys who can afford the time to do swaps are doing them in e30's as the barrier to entry, cost and technology wise, is much lower.
You are a hero in my book. Keep up the good work.
I'm hoping to one day follow the trail you've blazed.
