ok guys i just picked up my D15B VTEC enine runs and everything heared and all. so my question is how do i know if the guy just swapped the head on it or if its an actuall vtec block and all cause i have heared that mini me dont pass smog. so if that is what i picked up id rather be safe and put it back on market to sell but if it is truly a d15b vtec then ill be happy.
