I also have this motor the zc is stamped on the front of the block where usdm engine codes are found has vtec valve cover and most important of all it has a vtec solenoid I have not found any hard evidence on the power of this motor I have seen all kind of B.S anywhere from 125 to 140 but who do you believe but according to all the bs this engine is just like the d16z6 with a wilder cam or so they say and you know they say alot and it is also suppose to have it's own ecu the best place to call is an engine import company they should have all the info you require hope this helps you.
