Hi Mike - can you pm me some details on what was done with the motor? I've got an '03 M3 track car that hasn't had much internal work done. So far I've added new rod bearings, standalone ecu conversion with epic software, ss stepped headers v2 and a csl type intake. At this point, I'm not happy with the hp it's making and so I've been considering doing more with the motor. Question is what could I reuse and what would have to be done to get this kind of output?
