how can i tell where my engine came from?

[WankelsRevenge]

Hello all,
I'm new here and kind of new to RX7s all together. So any help on my new found obsession would be greatly appreciated. I just picked up a beautiful 88 convertible project that has a seized motor. So instead of rebuilding my motor I just went out and bought a used turbo motor. The guy I got if from said it came from Japan... but I have my doubts. I'm thinking it’s a hurricane Katrina motor, hope not though. That being said I would like to know if it is at all possible to identify the motor's origin. I found the number off of the front iron (f063658), under the alternator. I cannot find any way to decode this number, even called my local dealer with no luck. So if there are any rotary guru's out there that hold this knowledge, please help. Not just for me, but everyone else who also have wondered their engine's origin. Thanks in advanced!
