the new guy

hey whats up everyone, ok here my question, i just got a jdm motor from an importer, here the thing i wanted to get a d15b for a 96+ civic/w obd 2 ecu, the last year that they made the d15b but when i got the motor the engine code on it says d16a. now i called around and i was told that its not a usdm motor, but all the specs that i find say that the motor is rated at 115 hp to 120hp, but the importer is telling me that the motor that was sent was better and was about $200 more then what i wanted, so can anyone help with the real stats of a jdm d16a? thx for the help.....
