Mazda 323/GLC 1979 alternate engine
 

hi,
i have this rare mazda 323 RWD car and its engine has rotten away.
now i am thinking of replacing it with any other (the easier
the conversion the better).

do you have any bets on which engine would fit it and be easy
to install ? maybe mazda 626 929? which year? or maybe
a totally different make?

help greatly appreciated :)
