Does anybody know whether the heads are the same on a 939 and 821? Can the ecu from 821 be used on 939 engine and just flashed or something? My motor just took a crap and would like to use the opportunity to upgrade the power if possible. I've contemplated just buying the engine and ecu and dash board but that's going to be like 3-4k . Would like to just swap in the cylinder and pistons if that's possible? Anybody have any knowledge or experience they'd like to share? Much appreciated!
PS my vertical cam belt is shredded and once of the can gears feels jammed. Who knows what damage is done Im still tearing into the motor to gauge it.
