i had a 1.6 zm dohc in my 2003 protege and i am thinking about installing a 2.0 zm or zl engine.

will this new engine fit bolt to bolt on my existing mounts and transmission?

will the wiring harness be the same, and/or do i need to change the computer?

i need some help on this before i make a mess on expenses.

the initial engine overheated and no longer has compression.

 

Check your DOT laws before doing anything to make sure it'll pass inspection after the swap. ECU is a must imo. Wiring???

 

Physically I think it should work too, but I'm not the best person to ask about that one. Wiring would be best compared w/the donor car.
