    I just got a b16a head. I am trying to figure out what it is from. It has a pr3-4 stamped on the side of the head.

    thx

    PR3 and PR4 are the ecu codes for those cars
    seems like they labeled different components with these tags as well
    my b16 came with a P30 ecu and P30 is stamped all over the engine and components.... at least a few of them

    I could be wrong on this though

    PR3 is the casting code for the B16A/ITR head. B16A are PR3-4 ITR PR3-3.
