all you want to know is here. www.hondacivicwagon.com/

about 99% of the body is wagon-only. front bumpers and headlights are about all that are interchangeable on the exterior. any swap you can do on any other 4G Civic can be done on a FWD wagon. engine bay is the same size, perhaps alittle more space above the engine due to the hood slant. suspension intended for EF/DA can be used. more about suspension here.

we look forward to seeing your project.
