I posted in another forum, maybe there's no answer ... My d16Y7 has 150k. It needs a head gasket cause it overheats idling/sitting 5minutes; a 3rd/replacement of the cat - frequently blows p0420, catalytic below threshold .... I don't have the place or time for it, so I'd prefer to pay someone to drop a b18b1 motor/trans. IT HAS TO BE CALIFORNIA LEGAL, including 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. Advice please, where can I go for this?
