M-motor my rear end, hardly M when the s50/S52 engine was a tuned version of the M50/M52, not a true M engine, and M lovers didn't like that. They corrected the problem with the E46.
I do agree though that the M50 non vanos is a good base for turbo. If you guys are interested I will post the list of parts, where to buy them and the cost. I think the whole process will cost $2,000 roughly. Yet I still love the simplicity of my M30 engine...
Now... where to put the intercooler???
