I know this has probably been very much discussed, so im sorry to ask again, I am very new with Honda's and imports in general. Is it possible to replace the engine that is stock in my 1993 Civic Coupe DX with a VTEC engine? Also California Smog Regulations are a factor. Thank you very much for your time and thanks to anyone that can give me an answer! Thanks again!!
