Ok sorry to have to ask again but i just cant find an om 6 series diesel engine for less that 1100 pounds !! out of my budget

however i do have a 78 hp 12j na diesel for a land rover 90 , will this fit and would it be a powerful enough engine at 150 ish nm of torque ? i also have a spare 25 td but i measured the dimensions and the turbo would definitley foul the cab

. any suggestions please
many thanks and sorry to pester but i wanna get my mog rollin

thanks Kev
