Ok i'm new here and my girlfriend has a 1997 Civic DX. Its got the SOHC 1.6 liter D16 I think. I have heard of swapping the VTEC heads off the EX but not sure how to. I also want to know what else I can swap onto this motor since its in great running condition. So let me know if I can convert it over to DOHC or whatever and VTEC of course.
