i have a 1.6 zm with 97K on it and i got some bad news... it only has good compression in one cylinder and the rest is below specs.

i want to rebuild it a little stronger because its going to be apart.

my question is what is the best thing i can do to this motor other than getting a motor swap and where could i get the parts to do the build up?

please no jokes....serious answers only,

Thank you...
