i have a obd0 jdm b16 bottom end and a obd2 american b16 head i wanted to know if there is a why to convert the bottom end to obd2 since the block comes stock without a crank position sensor on the crank timing gear like on the obd2 cars? the head i converted back to obd2 from obd1. i dont wanna do obd1. i would rather do obd2.
