NON-OBDB16 IN OBD2 DC2

[MRKRAZECIVIC]

NEED HELP... I WANT TO BUY AN 95 INTEGRA WITH A JDM B16 THE GUY SAYS THE REASON WHY IT RUNS RICH ON OIL IS BECAUSE OF THE NON OBD MOTOR AND OBD CAR. THE CAR IDLES AT 1700-2000 RPMS KIND OF HIGH. IT HAS MINOR BOLT ONS( FULL EXHAUST, MSD IGNITION, AND INTAKE). NEED HELP TO SEE IF THAT IS THE PROBLEM OR IF IT IS SOMETHING ELSE I WAS THINKING MAYBE GETTING A NEW HARNESS TO MAKE IT WORK RIGHT. ANY ADVISE WILL HELP
