Aloha, my mitsubishi mighty max needs an engine. it has a piston detached from piston rod. (loud Clank) ive been looking for a replacement engine of the same model but its proven hard to find. what are my option for putting another engine in it? i dont know crap about engines, a buddy of mine will help with install. but i need to know what engine will fit in existing mount and transmission. any input would be appreciated.
