I have a 99civic. The d16Y7 is starting to show its 150k ... typical ... needs a head gasket cause it overheats idling/sitting 5minutes; a 3rd/replacement of the cat - frequently blows p0420, catalytic below threshold .... I'd like to save the hassle of a new car and drop a b18b1 motor/trans. IT HAS TO BE CALIFORNIA LEGAL I didn't like bein hasseled by the PD as a 'ricer' simply for using an AEM CAI on the d motor!! I want to have the factory Integra intake, ecu, etc.. I want to use a/c and pwr steer. I talked to some mechanics and they don't seem interested. Please give me advice, where can I go?
