What years were obd2 and obd1?

Other than injectors and the ecu is there anything different about the motors? Which are open/closed deck?

Thanks.

 

OBDI and II really dont have anything different in the motor itself.. its basically sensor related.. OBDII has two sensors instead of one(Oxygen) that is...I believe thats really the only different beside the ecu and dizzy...

 

P61 : 92-93 OBD-1 Integra GSR
P72 : 94-95 OBD-1 Integra GSR
P72 : 96-99 OBD-2a Integra GSR
P72 : 00-01 OBD-2b Integra GSR
P73 : 96-00 OBD-2 Integra Type-R (JDM & USDM)
P74/75: 92-95 OBD-1 Integra LS/GS
P75 : 96-99 OBD-2a Integra LS/GS
P75 : 00-01 OBD2b Integra LS/GS

 

Thanks. Thats what I thought.

Does anyone know about the open/closed deck?

 

I'm running H series now, I know the 92-96H is closed deck and the 97-01H is open deck, not sure about the B series, lil help?

 

Im pretty sure the OBD2 Cars come with a Crank Position Sensor on the oil pump.

 

Its actually called a Crank Angle Sensor.
