I pulled the stock D16Y5 out of my 97 civic HX two years ago when I swapped in my B18C1. I understand it has a SOHC VTEC-E system (goes from 12 to 16 valves). Do people usually throw these engines away or can some good be made of them? I have a friend with a 91 CRX DX who has a bit of mechanical background who thinks he can get some power out of it with a cam. Any thoughts? Is he an idiot?
