BMW k75 or fire 1108 engine swap. Witch would be easier to do? I want to do an engine swap on my aircooled 126 and want to decide between this 2 options, I searched the web but I can't find too much information about it. If anyone has done one of this and can tell me what parts I would need to do one of this swaps and also wich one would require less fabrication and also most importantly wich one would be a cheaper option. Thanks in advance.
