Since E37 is bored up to 96.8mm while the stroke remains with 84mm following E32, does it mean the stroker set and all other stuff follow E32 M112 ? Mechanically speaking, can I change only the cylinder block and the pistons to fulfill the conversion ? I was told the crankshaft differs also. I wonder if there are a lot more hardware items required to change along as far as a successful conversion is concerned. Thanks !
