Plan on about $1600 in parts to convert, but you get a lot of new stuff that way that you should replace anyway (clutch, mounts, guibo, etc). Driveshaft is replaced also. LS only came in sport package cars (the "s" after 325i is for 2D, not sport - sport had different seats, wheels, and LS). 3.15 was the standard ratio, 3.91 from an auto, 3.46 is about the best for all-around.
