No one ever said they were the definitive resource on ZC motors. I said that I thought there were two, there may be more then 2 types, although I sure can't find anything on them. I know there's a 1.6 DOHC and a SOHC/VTEC motor.
and although I haven't checked yet.... Im sure that lil' ZC is modded, and stock it can't stand up to a stock 1.6DOHC/VTEC or 1.8DOHC VTEC.
