so if i havea obd2 b16a2 in there i can use my oil pump crank sensor

also if i cant how do i do i bypass trick so it wont throw and code a cause me to fail

and will it be fine just to use for emssion problems i am getting the cams from mr.kidd
and i dont want to blow the motor or have any other problems with it when it comes time to pass emssions

also will it be better to runa chipped p28,p30 ecu witha conversion harness or is it better to run something like a vafc, msd dashawk, unit with a p2t ecu and tune it that way
