Thanks for your input, but I'm asking these questions because I have an OBD1 car, I had to change the OBD2 M52 engine to OBD1 which is a single Vanos. the double Vanos is a different animal and the S50B32 is a OBD2 engine. Also IMO the S50B32 is the best inline 6 BMW has made and in the US being rare. I've soured an engine for 1600 bucks with 6 speed trans. So since the S50B32 isn't widely available in the US i haven't had time to play with one nor see a swap for myself. But thanks for your input |
