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.
