BMW Engine Conversion
Shopping List

 

layout of bits

Listed below are items needed to complete your conversion.  As engines are sold in different ways, i.e. some with ancillaries some without.  I have quoted the engine as bare (crankcase, barrells, heads and normal covers).  Nearly all parts can be bought new or secondhand.  I have placed "new" where I recomend the purchasing of new parts.
