I was just wondering, besides the ecu in the obd 1 and obd 2 integra gsr motors, are there any differences? I know the ecu's are different, but are there any actual differences with the motors? The reson is, if I do a gsr swap I was thinking of getting like a 98' drivetrain and using a 95 ecu because my car is obd 1 and I don't want high mielage on the motor I get. I'm just wondering because I've heard obd 1 motors put down more hp to the wheels than the obd 2 motors.
