So i have a 93 honda del sol SI. I know its for sure an SI because all four wheels have disc brakes and i know that only SI del sols have that. I also know that the 93 del sol came with a d16z6 engine and that they are vtec, however my cars engine doesnt say vtec on the top of it. I heard some honda engines dont say vtec on them but they still are vtec. Is there any chance my car might not be vtec? Or is it? Thanks for the help.
