This is a page I found on a turbo M10, it is on an 1984 bmw 318i, but it has the same motor as the 320. It has loads of info on the turbo project. Great page to research and get ideas

http://home.att.net/~jroal/jay/bmw.htm

i have read over that page many a time, its got lots of good info on it

yeah, i've got that one bookmarked :) (altho they need to get rid of that l-jet....and tune that baby for more power......hopefully it's next owner will tune it optimally)

maybe i'm partial to e21's or think paul is the m10 turbo king of north america (lol :biglaughb ), but i like 320i.com (http://320i.com) a lot better :buttrock

yeah, but he is a little stingy on information and pictures......Maybe he doesn't want to get all his secrects out

My friend is going to buy that car from him.
