I have an JDM OBD1 SOHC VTEC motor that came from an automatic. The block is stamped ZC.

I just have a few questions:

1) What is this motor in America?(D16Z6???)
2) Does this motor have a different cam because it was an auto?
3) Are any of the other engine components different? (pistons, rods...)
3) What are the specs of this engine? (i.e. Horsepower, Torque, factory redline, compression etc...)
4) What car did this come in in Japan?

Any help would be very appreciated! Thank you...
