ok im really sorry if this has already been totally and thoroughly discussed and/or explained but for as much as i search i can't seem to find an answer. I own a 1998 gs (every option of the gs-r besides the vtec). I have a friend who tells me that in order to upgrade to vtec all i have to do is strap on a 1996-2001 b18c head (which i believe is the gs-r) and the gs-r ecu. I have two questions regarding that. (1) is that true and (2) given that that is true is my bottom end the same as the 1998 gs-r or should i upgrade that as well. Any help that anyone could provide would be great.
