Exactly what he said, but Honda doesnt have bad tranny issues as say Dodge does. The only problem you may have those issues if you Turbo, or Supercharge a K20. Abuse after abuse a lot will hurt it deffinently, but no matter what Honda is built to last.1996-2000 would be the 6th generation honda civic
Depends on who you ask and what your criteria are on the engine.
If you want a dependable, great gas mileage engine that has some pep to it, then yes its worth a damn.
If you want to go fast, but have transmission problems that you ***** and moan about constantly, then the K20 is in fact for you.
