#91556 Some one correct me if Im wrong but a 5 million stamp is obd1 and a 1 million stamp is obd0, if you look above your headers on your head twords your cam side their should be a stamp like "p30" or "pr3". also what ecu do you have?

#91661 Also most people will say a "pr3" motor and ecu is obd0 but their are the rare obd1 pr3-j51 (with a three plug ecu) witch I have. the pr3 came in the 93-94 obd0 jdm integra xsi. but a few were obd1. you can tell real easy by the ecu that came with the engine. if it only has two plugs than it's obd0, three plugs for a obd1.

again any one please correct me if Im wrong.
