what all do i need to swap on the b16a1 to make it a obd2 b16. This motor is going in a 2000 civic si. i already have a new honda obd2 oil pump with crank position sensor. i have a complete b20 vtec, with a obd2 b16 head, and i have a jspec b16a1. i dont want to swap the head over to convert it. Is there an easier way to do that?
