on a b16 engine will an obd1 dizzy work if the rest of the car is obd0. I will be converting to obd 1 in a month or 2 but I am getting the dizzy in a few days and I want to ops check it before it gets to far past the day I purchase it.

also when I replace the dizzy do I need to use a timing light or will I be ok if I mark the location of the rotor and line up the cam gear arrows ( so that they point to each other ).
