So after some research and some serious problems with my motor, I'm wondering if and how a pr4a11 ecu will work properly with a 97 b18b? Because thats what it has...The pr4 at its latest is obd1 right?

 

Pretty sure that might be from an obd0 car, but if you dont have a jumper harness it won't work either way. The ecu came from a DA so it should be ok for your motor, but obd2 ecus are generally cheaper and if your not planning on building the motor save your self the cost.

 

There are P74s that are OBD1 from 92-93 integras that'll work fine.

 

HondaPartsHero is correct about the 92 93 PR4 ecu being OBD1 and it will work just fine with an OBD2A to OBD1 jumper harness in your car (as long as its a manual transmission).
